I'm thinking about setting up my Parts car (85 GT) for the SCCA ITA class

In the rule book they specify that SOCK / OEM Brake rotors & calipers MUST be used or equivalent replacement parts

also the SCCA specifically requires that a Fiero in the ITA class must run ((Front) 260mm or 247mm Disc & (Rear) 260mm or 247mm Disk

247mm = 9.7"
260mm = 10.2"

So my question in what "Stock/OEM" brakes are 10.2"?

------------------
1986 SE 3800SC/4t65eHD (12.871@104.96)
HX-40, FrozenBoost I/C, 80lb injectors & E85 Coming soon.....

The stock 88 brake rotors are 265mm in diameter.

Thats what I was afraid of, in a very direct but round about way they are saying you can run '88 brakes on a 84-88 Fiero and Vice-Versa

To road race with '88 brake parts would be cost prohibitive, think 84-87 OEM brakes are up to the task ?

The rules don't say anything about the booster though.

The rules do however say if it's not in the rules than it needs to be Stock/ OEM

I was hoping the grand am brake upgrade might be legal. (it should be..... Stock appearing single piston caliper & stock diameter 9.7" rotors)

I Gaurentee I would never be busted on if I ran GranAm brakes, but I don't want to be a "Cheater" I just want my Comp license and have some fun.

It seems like NASA PT and SCCA IT are just about the same thing, and it seems like if your legal in NASA PT they let you run in SCCA IT and vice versa other than that we can go full chassis car and run in GT1 or GT2 but that's a bit much, since me and a few friends just want our comp license.

I'll just put the highest quality pads and rotors on her and see how it does. I'm not worried about the performance of the stock brakes, I was just concerned about warping, rotors rarely warp while driving.... as long as I take care of them a cool them down before parking I'm sure they will do alright. After all other cars in the same class have to run 7" rotors in the front and drum brakes in the rear
