2024-1-30-Tubular rear subframe


There is a current rule for Tubular Front subframe/K-member being 10pts (bolt on only).

Would this also apply to a rear tubular subframe? For example, a Pontiac Fiero has the engine mounted in the rear and uses a subframe that is essentially the same as a FWD front subframe except it wouldn’t have a steering rack. Would this also be considered 10 points? If not, how many?

Bolt in subframe 10 points each Front or Rear
