I'm using a Porsche G50-01 transaxle, inverted so that the car goes forward. The adapter, flywheel, and clutch are Kennedy Engineered Products. The shifter is a rod type with Thompson ball- bushings and Apex u-joints.
Rear uprights are Porsche 996 and the rear calipers and rotors are from the front of a Porsche 928 S4. I had the rear hubs re-drilled to convert the original 130mm bolt circle metric threaded holes to a 5 stud on a 5" bolt circle ("5 on 5") pattern so that I could use Bassett circle track racing wheels. The new studs are coarse thread 5/8" -- a standard in circle track racing but using a different taper lug nut.
