It is 10.5 inches like the GTA and like every other model... there were no rear disc brake options, they're all the same.

Re: Rotor diameter in the recaro?

Because it's just as commonly referred to as a 10" rotor since nobody needs to care what the exact size is since there are no other sizes available to distinguish it from.

So you are in the ballpark 10"+/- .5" . Sounds reasonable, however I would not let you do any measuring for me.

Also the first time I heard someone say "commonly referred to as as a 10" rotor". What about 11.655 dia rotors???

Re: Rotor diameter in the recaro?

the 11.65 rotor is for the 1le optioned cars, it requires a different spindle and caliper. It will not replace yours.

Re: Rotor diameter in the recaro?

Since it wasn't available in 1982, it doesn't matter. In any given year there was only one rear disc brake package used, so you don't need to care what size they are.
