  • 2020 R-X Rule Change Proposals - Submit 'Em Here!

    Have a rule change or clarification you would like to propose for the 2020 RallyCross rules? Submit your proposal on this thread. Be sure to include the proposed language for the change and a brief explanation of why you are proposing the change. The rule change submission period runs through August. Member comment on proposed changes will take place in September, followed by Rules Committee review in October, and final review and approval by the RallyCross Board (RXB) and the SCCA Board by year-end.

    Please note that the RXB has placed a freeze on the Constructors class rule set for 2019 and 2020. The intent of this freeze is to provide a stable, predictable build environment for the first few years of this new class.

    Last year, the RXB initiated an online survey to solicit member feedback on rule changes proposed for the 2019 rules. More than 450 participants completed the survey, which was significantly more feedback than we received using the previous “comment on the Forum” process. For 2020, we’re working on a better system for distributing the survey link to ensure universal access to the survey for all competitors. Watch for more information about the member comment survey link in early September.

      Please allow and clearly outline CrossKart vehicles inclusion in the Constructor Class (Include motorcycle based engines used in these production cars)



      Can these 600/750/1000cc CrossKarts (Actual Official European Rally KrossKart Buggies) run in the local SCCA Rally Races in Midwest?

      Current rules are a contradiction to "CrossKart" designs and confusing.

      "Summary of changes to the RallyCross Rules for 2019:

      1. Clarify that Crosskarts, Formula Cross, Legend cars, and tube-frame vehicles are eligible to compete in Constructors classes if they meet applicable preparation allowances (e.g. production-based engine). 3.1. ... The following types of vehicles are currently not eligible to compete in Stock, Prepared and Modified categories: ATVs, UTVs, side‐by‐sides, Trophy Trucks, Crosskarts, Formula Cross, Legend cars, and tube‐frame vehicles. Trophy Trucks, Crosskarts, Formula Cross, Legend cars, and tube‐frame vehicles are eligible to compete in the Constructors category subject to applicable preparation allowances."

      F. Constructors Category

      Constructors Two Wheel Drive (C2) Constructors All Wheel Drive (C4) Preparation allowances:

      1. The Constructors Category is intended for four-wheeled vehicles altered in excess of the Modified Category allowances, such as dune buggies, sand rails, tube frame/chassis vehicles, kit cars and similar types of custom-built vehicles. 2. Minimum track is 42 inches measured from the center of the wheels. Maximum height is 90% of the average track width measured at the highest point of the roll cage. Minimum wheelbase is 72 inches measured from the center of the wheels. 3. Engines must be naturally aspirated, internal combustion, passenger car or light truck-based, and with no more than four (4) cylinders or two (2) rotors. Motorcycle, ATV, UTV and similar engines are not allowed."


      Can the Euro/USA distributed production based Krosskarts listed below in links be approved? They are popular and use 600/750/1000cc type motorcyle engines? They are used in other sanctioned rally series.


      "3. Engines must be naturally aspirated, internal combustion, passenger car or light truck-based, and with no more than four (4) cylinders or two (2) rotors. Motorcycle, ATV, UTV and similar engines are not allowed."


      SCCA RallySprint/RallyTrials Rules:

      "2 RallySprint vehicles will be classified into one of four categories:
      a RallySprint Two-Wheel Drive Under 2.5 Liters (R2U) – for front- or rear-wheel drive vehicles with adjusted engine capacity of 2499 cc’s or less.
      b RallySprint Two-Wheel Drive Over 2.5 Liters (R2O) – for front- or rear-wheel drive vehicles with adjusted engine capacity of 2.5 liters or greater.
      c RallySprint Four-Wheel Drive Under 2.5 Liters (R4U) – for all- or four-wheel drive vehicles with adjusted engine capacity 2499 cc’s or less.
      d RallySprint Four-Wheel Drive Over 2.5 Liters (R4O) -- for all- or four-wheel drive vehicles with adjusted engine capacity of 2.5 liters or greater.

      Adjusted engine capacity is the actual displacement for normally-aspirated engines or 1.4 times the actual displacement for vehicles with forced induction (turbochargers, superchargers).

      C Other classification systems will be considered and should be listed on the sanction application.

      D Vehicles that meet the safety requirements and are currently log-booked to compete in other non-SCCA racing or rally series, such as SCCA, Rally America, GRC, NASA, SCORE, FIA, and USAC, are eligible to compete at the discretion and approval of SCCA or Event Chairman."


      These are here in the USA and being raced (They are also the baseline for European CrossKart Rally Racing and are/have been added to rally series)

        Greetings, I have a few rules suggestions.

        Modified/Constructors Classes. An allowance for running Nitrous Oxide. I grabbed the rules set from Formula Drift since they see crazier car action then us I think there rules set would be sufficient for our sport. (The reasoning for this is the newer delivery controllers are able to slowly ramp up the spray so it is a boost not a solid shot. non-boost cars could use this to even the field without a forced induction upgrade and make it very manageable.
        NITROUS OXIDE
        A. Nitrous Oxide bottles must be securely mounted inside the body line and protected within the confines of the factory frame rails and factory bumper or tubular bumper structure.
        B. All Nitrous bottles must be recertified every 5 years and stamped to indicate the last inspection date.
        C. All Nitrous bottle must be stamped with minimum DOT -1800 pound rating.
        D. The use of commercially available thermostatically controlled bottle warmers is accepted. The use of any other method of externally heating nitrous bottles is prohibited.
        E. The use of plastic bottle brackets is prohibited.
        F. Nitrous bottles located in the driver compartment must have a “BLOW DOWN TUBE” which consists of a pressure relief valve (Example from NOS- Part number NOS 16169) and be vented to the outside of the driver compartment (Example from NOS- Part number NOS 16160).

        Stock Classes - Move the Aftermarket Radiator rule set from Prepared classes and allow it in Stock class. Unlike Solo we spend a lot of time a WOT going sideways at under 20 mph. The factory cooling systems especially on Forced induction cars is not designed to operate effectively in these conditions. Trying to protect peoples cars from damage is a common rule set in stock class. Skid plates, mud flaps, roll cages etc. Aftermarket radiators usually have more volume which adds weight in the coolant department. We need to help peoples cars stay together. Please also be considerate of geography. In the North East this might not seem like a big deal. But at 105 Degrees in the high altitude dry Desert areas this is a big deal for all cars. But forced induction cars always struggle. Z.B. was always having cooling problems with his Stock class STI.

        Modified classes - The currnet exhaust rule is.
        10. Exhaust systems may be replaced with any material with the following requirements:
        a. The exhaust must exit to the rear of the driver.
        b. The exhaust must comply with local noise restrictions.
        c. No catalytic converter is required
        My proposal is to allow more options for the modified class.

        E. 10. Exhaust systems may be replaced with any material with the following requirements:
        a. The exhaust must exit to the rear of the driver or to the side of the car
        1. If the car uses a side exit exhaust in front of the driver that side of the car must have proper windows on that side to prevent CO inhalation.
        2. If the car uses a side exit exhaust in front of the driver on the drivers side of the car there must be sufficient labeling informing the stater of its location so that they may know relocate themselves prior to starting the car.
        b. The exhaust must comply with local noise restrictions.
        c. No catalytic converter is required.

        (Solo allows side exit exhausts anywhere on the car; it has been a long time rule in their book and they see all the same staging and racing situations that we do. So I could use their long standing with the rule as proof of it being safe. As long as we comply with noise I think it would be a fun option for the mod classes."

        Constructors class - Place the class on hold and pull the rules from the rule book. Form a new committee for the rule using a majority of the most extreme building RallyCross members across the country. The current rules are obviously not working for anyone. The people most likely to build a constructors class car are not doing so... It is currently a class for overweight fully caged stage cars. Just being real. Let's fix this now before one person builds a car and ends up being alone for years in the class.


        I think that is about it for me....
