RallyCross Member Advisories


Hand held devices, including cell phones, cameras and video recorders, are considered “loose items” under Section 6.3.A of the RallyCross rules. Competitors and passengers are not allowed to use hand held devices during runs. Video recording devices may be used during competition but must be mounted to the vehicle, not hand held. 
6.3 VEHICLE/DRIVER SAFETY (Mandatory for all SCCA sanctioned RallyCross events. See Article 4.1)
All vehicles must pass safety inspection on the following points prior to competing. This applies at each event entered. Entry fees, if already paid, will be refunded if a car fails to pass the safety inspection. A safety inspection is not concerned with class compliance. 32
A.  All loose items, inside and outside the car (including the trunk and storage areas), must be removed. Hand held items, such as but not limited to, cameras and cell phones are considered loose items.



1) The use of and alternate or replacement (no airbag) steering wheel is not permitted in Stock or Prepared categories.

4-17-2013: The use of Methanol is not approved at any SCCA RallyCross events


12-5-2012: Currently 6.2.C.2 reads:

Tires must be DOT approved. Tires marked “For competition only”, “Not for street use” or similar, are not allowed. No part of the tire may be modified or altered from its original form, either through addition or subtraction, other than normal wear. No studded tires are permitted unless ice or snow is present. Studded tires may not be homemade using bolts or screws. Only street-legal studs are allowed. Tires may not interfere with any parts of the car (fenders, fender liners, suspension, etc).

This has lead to some discussion that tires must be the stock by the letter of the rule, but that was not the intent.  To clarify, any size tire is legal as long as the tire does not rub on car.


3-8-2012The RallyCross Board (RXB) announces the creation of a new class. For 2012 and beyond, The Two-Wheel drive Modified class will be divided into Modified Rear (MR) and Modified Front (MF). There are no changes to the existing rules of preparation.

This change allows B-Spec classed cars to be class eligible for MF with the deviation of the B-Spec tires. B-Spec cars can run any tire and wheel within the RallyCross Modified rules. The RXB will be reviewing the B-Spec participation numbers to see if a separate class and championship is warranted.
