The Midwest RallyCross
Championship is a year-end points series, in which specific events from the
participating regions are included as Series events.
The Series is open to all
drivers; however, each driver must compete in Series events in at least two
different regions, in order to score year-end points.
Drivers will be awarded
points based on their finishing position within their class, by using the following
points schedule:
1st in class 20-points
2nd in class 18-points
3rd in class 16-points
4th in class 14-points
5th in class 12-points
6th in class 10-points
7th in class 9-points
8th in class 8-points
9th in class 7-points
10th in class 6-points
11th in class 5-points
12th in class 4-points
13th in class 3-points
14th in class 2-points
15th in class 1-point
Anyone finishing below 15th
place, or those drivers who either DNF an event, or are DSQ’d from an event
will not receive points.
Year-end Championship
trophies will be awarded to roughly 1/3 of the top drivers with the most
accumulated points for the Series. In addition, there will be a trophy for the
top driver in each class.
In the event of a tie for
year-end points, the first tie-breaker will be the driver with the most 1st-place
finishes in class, second tie-breaker will be the most 2nd-place
finishes in class, third tie-breaker will be the most 3rd-place
finishes in class, and the fourth tie-breaker will be the driver with the most
Series events entered. If there is still a tie, the overall results from each
Series events will be examined, and the driver with the highest overall
finishes will win.
1.
STOCK CATAGORIES
Vehicles competing in Stock
Class must be production-based, have a fixed-roof, and must have been produced
with normal road touring equipment capable of being licensed for normal road
use. Convertible vehicles must have a hard-top installed during competition.
Except for modifications authorized below, Stock Class cars must be run as
specified by the factory with only standard
equipment as defined by these Rules. Any other modifications or equipment will
place the car in one of the higher classes, as appropriate.
Alternate components which
are normally expendable and considered replacement parts (e.g., engine and
wheel bearings, seals, gaskets, etc.) may be used provided they are the same
type and size as the standard parts and
used in the same location.
1.1
Authorized Modifications
If a modification is not
specifically authorized in this or previous sections of these Rules it is not
allowed. It is not permitted to use illegal parts even if they have been set to
stock specifications.
1.2
Bodywork
26326. Accessories,
gauges, indicators, lights and other appearance, comfort and convenience
modifications which have no effect on performance and/or handling and do not
materially reduce the weight of the car are permitted. This does not allow
driver's seat substitutions. Delayed shutdown devices such as the "Turbo
Timer", which perform no function while the car is in motion, are permitted. Short-shifters, shift knobs and other interior
trim items are included in this list.
26327. Hood straps or fasteners may be added.
26328. Any
fuel tank cap may be used.
26329. Spare
tires, tools and jacks may be removed.
26330. A
harness may be added to either or both of the front seats. Seats may not be cut
to allow for the installation of alternate seat belts or harnesses. Passive
restraint systems may not be removed. A horizontal "harness bar" may
be used as part of the installation hardware for allowed driver restraints. It
may serve no other purpose (e.g., structural enhancement).
26331. Any
item that can not be held permanently in place by factory installed fasteners
may be removed.
26332. Aftermarket
body-kits are allowed, provided they do not replace any factory body panels
with a lighter-weight alternative.
26333. Strut tower bars/braces may be
added.
26334. Underbody
and wheelwell protection devices, and associated mounts are free. These may
serve no other purpose than the safety of the vehicle and bystanders. This
provision specifically allows the addition of skidplates and mudflaps.
J. Aftermarket pedal covers are allowed.
1.3
Tires
Any tire which is O.E.M. on a car eligible for Stock Class may be
used. Non-O.E.M. tires must meet the
following requirements to be eligible for use in Stock class:
26341. Any
DOT approved street tire, and any All-Season, or Snow tires which have lateral
tread gaps(gaps which do not run the circumference of the tire)of one quarter
inch(0.25”)or less, will be acceptable for Stock Class.
26342. No
Mud, Sand, or Rally tires are allowed in Stock Class.
1.4
Wheels
Any type wheel may be used
provided it complies with the following: wheel diameter and with are free;
however, the tread of the tire may not protrude past the fender by more than
one inch.
Wheel spacers are permitted,
provided the resultant combination complies with the track-width requirements
of this section. Wheel studs lug nuts, and/or
bolt length may be changed. .
1.5
Shock Absorbers
26356. The
make of shock absorber may be substituted providing that the number, type,
(e.g., tube, lever, etc.) system of attachment and attachment points are not
altered. Substituted shock absorbers may provide no more than two external
damping adjustments. Remote reservoirs are permitted and holes may be drilled
for bolts with which to mount the reservoirs, but bodywork may not be
additionally cut or drilled to provide for the routing of lines or the
positioning of the reservoirs. A hole may be added
through the bodywork to route the line from the reservoir to the shock absorber
body. Such holes may serve no other purpose.
26357. The
mounting hardware shall be the original type. To
facilitate the installation of commonly available aftermarket shock absorbers,
struts, or strut inserts whose shaft is larger than the center hole of an upper
mount assembly, that hole may be enlarged by the minimum amount necessary to
accommodate the shock shaft size, provided the following restrictions are met:
(1) the enlarged hole must remain concentric with
that of the original configuration;
(2) the enlargement of the hole does not require
modification of a bearing (as opposed to a washer, plate, or sleeve);
(3) neither the hole enlargement nor the location of
the shock shaft changes any alignment parameter.
Bump stops installed externally and concentric with the shaft of a shock
absorber may be drilled out to fit larger-diameter shock shafts. Bump Stops
with similar characteristics to those of the original may be substituted for
the purpose of installing aftermarket shock absorbers.
26358. The use of any shock absorber bushing material, including
metal, is permitted. This does not permit the use of an offset shock absorber
bushing.
26359. The interchange of gas and hydraulic shock absorbers is permitted.
Electronically controlled shocks may not be used on vehicles not originally
equipped with such units. Vehicles originally equipped with electronically
controlled shocks may use non-electronically controlled alternatives subject to
all requirements of 1.5.
26360. Shock
absorbers with adjustable spring perches which have been welded in the stock
position on the shock absorber are permitted.
26361. The
dimensional characteristics of the shock and relative placement of the spring
must remain as stock. If the spring perch on an aftermarket shock/strut is a
small amount (e.g. 1/4") lower than the standard
part, but the shock/strut otherwise complies with the requirements of this
Section, a shim may be added to the spring perch to raise the spring base to
the correct height. This shim must be permanently attached to the perch.
26362. Suspension
geometry and range of travel may not be altered. A suspension bump stop is
considered to be performing the function of a spring. The distance to the
initial point of contact with a bump stop may not be reduced, though the bump
stop may be shortened for the purpose of installing aftermarket shock
absorbers.
26363. The
bushing attaching the end of the strut to the body or frame on a strut type suspension
is a suspension bushing, not a shock absorber bushing. Suspension bushings,
including but not limited to those which carry the weight of the car and
determine ride height, may not be replaced with bushings of a different
material or dimension.
26364. A hole may be added in an interior body panel to provide
access to the adjustment mechanism on an allowed shock absorber. This hole may
serve no other purpose.
26365. The
fully extended length must be within plus or minus one inch of the dimension of
the standard part.
1.6
Brakes
26371. The
make and material of brake linings may be changed.
26372. Substitution
of clutch and brake hydraulic lines with solid metal or braided metal is
allowed.
26373. Alternate brake bleeder fittings such as "Speedbleeders"
are permitted They may serve no other purpose.
1.7
Anti Roll (Sway) Bars
Front
or Rear anti-roll (sway) bars:
1. Substitution,
addition or removal of any front or rear anti-roll bars is permitted.
2. Substitution,
addition or removal of anti-roll bars may serve no other purpose than that of
an anti-roll bar.
3. The use of
any bushing material is permitted.
4. No
modification to the body, frame or other components to accommodate anti-roll
bar addition or substitution is allowed, except for the drilling of holes for
mounting bolts. Non-standard lateral members which connect between the brackets
for the bar are not permitted.
1.8
Suspension
Standard, as defined herein, suspension springs must be used.
They may not be cut, shortened or collapsed. Cars with swing axle suspension
may be lowered sufficiently to achieve no more than two degrees of negative
camber at rest, and may use a camber compensator.
Both the front and rear
suspension may be adjusted through their designed range of adjustment by use of
factory adjustment arrangements or by taking advantage of inherent
manufacturing tolerances. However, no suspension part may be modified for the
purpose of adjustment unless such modification is specifically authorized by
the factory shop manual for non-competition purposes.
Replacement control arms for
vehicles having integral bushing/arm assemblies must be standard factory parts. This encompasses both alignment and ride height parameters, if
such adjustments are provided by the stock components and specified by the
factory as normal methods of adjustment.
If authorized by the
manufacturer, the use of shims, special bolts, removal of material to enlarge
mounting holes, and similar methods are allowed and the resulting alignment
settings are permitted even if outside the normal specification or range of
specifications recommended by the manufacturer. If enlarging mounting holes is
specifically authorized but no material removal limits are specified, material
removal is restricted to the amount necessary to achieve the maximum factory
alignment specification.
1.9
Electrical System
26401. The
make of spark plugs, points, ignition coil and high tension wires is
unrestricted including spark plug wires having an in-line capacitor .
26402. Ignition
settings may not be adjusted outside factory specifications.
26403. No changes are permitted to electronic engine management
systems or their programming.
1.10
Engine and Drive Train
26416. The
engine air filter element may be removed or replaced, open-element filters –
including Cold-Air intakes – are allowed; however, the intake system past the
Throttle Body must remain stock.
26417. Any
part of the exhaust system beyond (downstream from) the header/manifold or
catalytic converter, if so equipped, may be substituted. Stainless steel heat
exchangers are permitted only if the physical dimensions and configuration
remain unchanged. Modifications of any type, including additions to or removal
of, the catalytic converters, thermal reactors, or any other pollution control
devices in the exhaust system are not allowed and the system must be operable.
Replacement catalytic converters must be OEM
if the vehicle has not exceeded the 5-year/50,000 mile warranty period as mandated
by the EPA. Converters must be of the same type and size and used in the same
location as the original equipment converter(s). This does not allow for a high
performance unit. If the vehicle has exceeded the 5 year/50,000 mile warranty
period, replacement catalytic converters must be OEM-type.
26418. Silicone replacement coolant hoses, and vacuum lines are
permitted as alternate components. This allowance does not permit
silicone intercooler hoses.
26419. A
device for locking out reverse gear may be used.
26420. Any
oil or grease, including synthetic, is permitted.
1.11 Classing of Vehicles
A.
Vehicles
will be divided by displacement, as well as number of driven wheels.
B.
The
cutoff for displacement will be as follows: all naturally-aspirated piston
engines of 2.4 liter displacement or smaller, all forced-induction piston
engines of 1.9 liter displacement or smaller, and all naturally-aspirated
rotary engines, will be classed together by drivetrain configuration. All
engines above these displacement limits will be classed together by drivetrain.
C.
The
resulting 4-Stock Classes will be as follows:
2U
= 2-wheel drive vehicles at, or under, the displacement limits listed above.
2O = 2-wheel drive
vehicles over the displacement limits listed above.
4U = 4-wheel, and
All-wheel drive vehicles at, or under the displacement limits listed above.
4O = 4-wheel, and
All-wheel drive vehicles above the displacement limits listed above.
D.
Additionally, event organizers may choose to add one Truck/SUV Stock Class, if
the number of eligible vehicles is 3-or more.
2. PRODUCTION CATAGORIES

Rally cars with current logbooks are eligible.
Vehicles must be street-licensed,
closed-body, four-wheeled models, which are available for retail sale(in
minimum quantities of 1000 per-year)are legal. They must be standard models as
sold, except for authorized changes. A “model” is a manufacturer’s specific
designation(e.g., Dodge Shelby Charger, Dodge Omni GLH, Volkswagen Golf GTI,

Cells, not to exceed the capacity of the stock fuel tank, or
15-gallons(whichever is greater), are allowed to replace the stock fuel tank.
Fitting of such cells must conform to Article 5.8.B of the Performance Rally
Rulebook. Rerouting of fuel line is allowed. Fuel lines, which run inside the
passenger compartment, must be as prescribed in Article 5.8.B of the
Performance Rally Rulebook.
2.2 PRODUCTION GT
The Production GT Class is
open to all vehicles that fall within the rules of the Production Class, other
than an adjusted displacement of 2651cc or greater. All Production GT Rally
cars with current logbooks are also eligible. All allowances listed in Section
2.1 apply.
2.3 RALLY TRUCK
Performance Rally Trucks,
which have a current logbook, will be allowed to compete in the Production
Class as defined in the Performance Rally Rulebook. If there are enough Rally
Trucks to warrant a separate class at a given event, organizers are free to do
so. Any street Truck or SUV which are prepared beyond Stock Class limits, yet
fall within the allowances of Production or Production GT Class, will follow
the same displacement multiplier formula for determining class.
3. OPEN CATAGORIES
3.1 Open Class
Vehicles competing in the
Open Class must be based on production vehicles; Non-production based vehicles,
built from the ground up, are specifically prohibited. Innovation and
modifications within the rules is encouraged. In addition to the allowances for
the Stock and Production Classes, freedom is given to modify any component of
the vehicle, providing that it is not otherwise restricted below.
A.
The
engine is unrestricted, but must be derived(at least the engine block)from a
product line offered by the manufacturer of the vehicle.
B.
Except
for doors, bolt-on body pieces may be constructed of an alternate material.
Roof vents may be added.

No
electronic control, other than what was original equipment on the vehicle, are
allowed for the following components: suspension, steering, breaking, gear
change/clutch, front and rear differentials. Simple engine-cut during a
mechanical gear change is allowed.
G.
The
use of sequential gearchange mechanisms is not permitted. This rule is waived
for vehicles with automatic transmissions.
3.2 Group 5 Class

3-valves per cylinder = 1.1x
2-valves per cylinder = 1.0x
Pushrod = 0.8x
Diesel = 0.8x
4. CLASSING AND PROTEST PROCEDURES
4.1 Classing
Every effort will be made by
the Tech inspector to class vehicles correctly; however, it is the responsibility
of the competitor to disclose any and all vehicle modifications to the Tech
inspector. After the initial technical inspection, the responsibility for
policing incorrect classing is transferred to all competitors.
4.2 Protests
If a competitor has a complaint
about another competitor whom they believe to be classed incorrectly, that
competitor should contact the Event Chair.
The Event Chair may then discuss the matter with both competitors, the
Tech inspector, Safety Steward, and/or anyone else the Event Chair deems
relevant to the protest. If the protest
is upheld and timed runs have not begun, then the at fault competitor will be
placed in the proper class. If timed
runs have begun, then the at-fault competitor will be re-scored in the correct
class for the final event results
The decision of the Event
chair will be final; however, if the competitor chooses not to compete in the
correct class, that competitor will still be allowed his/her runs, but will not
receive any official time or points for the event.
In addition, any competitor
deemed to have displayed un-sportsmanship-like conduct, may be disqualified and
asked to leave by the Event chair, if seen fit. In such case, that competitor
will forfeit any and all recorded time, points and paid entry fee.
5. TIMING AND SCORING
Each competitor’s runs shall
be timed in a fair and reasonable manner. Each pylon that is either knocked
over, or displaced from their marked position during a run, will count as a
2-second penalty added to the total time for that run. Additionally, the Event
chair may specify certain pylons(ie: near the start and/or finish)which result
in a DNF for that run.
Before the start of
competition, the Event chair shall announce a DNF Bogey-time. This Bogey-time
will count as a competitor’s time for any runs that are either not completed,
or which the competitor does not follow the course completely – including missing
a gate, not completing a slalom, skipping one or more cones in a slalom, or
passing through a gate in the wrong direction. Competitors are allowed
to pass through a gate more than once.
The cumulative time for all
of a competitors runs, minus that competitors slowest/worst run, will be used
to determine finishing position in class.
A.
Confirm
that vehicle has a fixed-roof in place.(T-Tops are allowed, but must be
installed).
B.
Ensure all loose items, including driver’s-side floor mat, are removed
from the interior and/or trunk.
