CACC Rule Change Proposal
RCP-2026-6279

For Hill Climb events, Max class participants who take advantage of of the
preceding rule will be bumped up on class. For example, a Max 5 car
running 40TW tires would be Max 4. For Hill Climb events, Max 1 class
participants who take advantage of the preceding rule will be bumped up to
Max 1R

For Hill Climb events, Max class participants who take advantage of the preceding rule will be bumped up into the next applicable class following the SCCA Time Trials rules. At the bottom of each Max class, there is a line stating where the class in question gets bumped to. As an example: Under the rules for Max 4: 2.All Max 4 eligible cars underweight by up to 300lbs go to Max 2.

For ultimate clarity the following will apply:

Max 5:
2. All Max 5 eligible cars underweight by up to 300lbs OR using sub 200tw following 18.7.2.7.1 go to Max 4. If Max 5 eligible cars are both underweight by up to 300lb AND are using sub200tw tires following 18.7.2.7.1, move to Max 2. Lighter than that, welcome to Unlimited.

Max 4:
2. All Max 4 eligible cars underweight by up to 300lbs OR using sub 200tw following 18.7.2.7.1 go to Max 2. If Max 4 eligible cars are both underweight by up to 300lb AND are using sub200tw tires following 18.7.2.7.1, move to Max 1.

Max 3:
2. All Max 3 eligible cars underweight by up to 800lbs OR using sub 200tw following 18.7.2.7.1 go to Max 2. If Max 3 eligible cars are both underweight by up to 800lb AND are using sub200tw tires following 18.7.2.7.1, move to Max 1.

Max 2:
2. All Max 2 eligible cars underweight go to Max 1 up to the Max 1 minimum weights OR using sub 200tw following 18.7.2.7.1 go to Max 1. If Max 2 eligible cars are both underweight by up to the Max 1 minimum weights AND are using sub200tw tires following 18.7.2.7.1, move to Max 1R. Lighter than that, welcome to Unlimited!

Max was not intended to “bump up one” when something requires it (weight typically). The bumping “path”. If we are continuing to allow this bumping, it should follow the path laid out in the SCCA time trials rulebook. For clarity, it should be known that modifications (following the same path) are allowed from the class below it. For instance Max 2 does not list the engine configuration listed in max 3, however it is allowed to be used in max 2 irrelevant of whether it is below the minimum weight for max 3.
