I'm curious about prep tips for these cars - suspension setup, brakes, diff.
Is there anyone on here who used to race these?

1985 Mazda RX7 Spec7 converted to ITA. Don't remember Spec7 if suspension was adjustable. In same RX7, ITA trim adjustable suspension including shocks, 4:88 L/S diff, Paul Yaw carburetor, FPR/gauge, special coils (don't remember brand), header/exhaust system (don't remember brand) brake ducts, adjustable brake proportion valve and more I'm not remembering. Car had way more talent than driver. After a BIG situation where the rear end wanted to lead, it's parts were sold all over east of the mighty Mississippi.
Old brain also, thanks Steve. Suspension, Panhard rod and tri-link. Did similar front toe and a guy heated/welded solid rear axle housing to gain a tad of toe in.
I'll admit to being old. And I raced an IT7 before switching to SM. I'm probably not much of a source for useful info about setup. Setup was "1/8" toe out" and as much camber as I could manage in the front. I didn't have adjustable swaybars, so never had to worry about that. I think the rest of the suspension was the basic ground control RX7 IT setup of the day. Tokico shocks. 4:88 was the diff to have, but mine didn't have one. Mine had MSD ignition, adjustable brake proportioning valve, Mike Van Steenberg's (ISC) brake ducts (I toasted countless rotors before I put in the brake cooling). I ran hawk blue pads - loved them in the RX7; hate them on the miata. ISC's stainless header (a SS copy of the racing beat header). Simple panhard rod - not watts or tri-link which I understand to work better.
