[Cobra Pack]

CSX2136 (which is pictured above), CSX2137, and CSX2138 all raced originally with Kidney Bean wheels. As they moved into later '63 and the '64 seasons, they were all raced at various times with FIA wheels because they were more readily available and were wider. Once they started putting alloy "comp" girling brakes on cars (fia and cutback door team USRRC cars) the Kidney Beans could no longer be fit on the car because there were clearance issues. Kidney Beans have a lot of structure on the inside and were balanced by screwing washers to the backs of the wheels. Since I am running alloy comp girling brakes on my repro comp car, I needed to have PS adjust the backspacing to accomodate the big brakes.
