Following is a post from the production car site for the 2013 Ronoffs post qualifying tech.
How about the Line Chief ??? for Spec Miata post a heads up for the Spec Miata cars.
Some of the obvious are already on my list such as spoiler, reverse gear & kill switch.
Post race is fairly well set, bore, stroke, cam lift if limited, compression ratio if limited, carb/intake, porting if limited and valve size. I'm considering checking rods and cranks this year for those restricted. I will do this in advance if you are into the motor and I'll mark and seal.
