I have a 1990 Miata, I know it is SM illegal, what about ITA...however a few things I think would throw it out. The cars specs are:

-KYB AGX shocks
-Tein springs
-Seam welded chassis * main worry
-Delrin bushings * another worry
-OPM strut bar
-Header
-Exhaust
-Intake

It has a lot of other mods I know would be IT legal, I would not be competitive, but would not want to break the rules. I do not have a new GCR, so I cant look it up. Any input greatly appreciated! Thanks!!!
