To summarize:

- The 12A-equipped RX-7 is allowed in STU in ITA trim (no porting) at 2280# (since the chassis was built through 1985).
- The 12A engine is allowed in STU with "street porting" at 2350#
- The 12A engine is allowed in STL with no porting at 2535# (changed Dec Fastrack).

If anyone thinks these should be lower, please do submit a request for the weight you think it should be to the CRB at http://www.crbscca.com.

Not directed at you specifically Greg , although I applaud you taking the role of publicly furthering these discussions. The original posters question was why the 12a was so heavy in STL. In that class I have not found any allowances for porting of a carb change. As far as I know there are no allowances that would let the car make any more power that it does in ITA/IT7. Given that like the original poster I am not sure why the cars was speced in STL at 255 pounds more than the IT car. Hence my question, what am I missing.
