I want to put on different wheels. Its a 97 Z28 with the white wheels on it, and I found some nice ones made by centerline. What I need to know is what size are the wheels, and what is the back spacing on them? Thanks

 

noone knows?

 

Stock Z28 (or Firebird) wheels are 16x8, 55mm offset, approx 6-5/8" backspace. The bolt circle it 5 on 4.75" (120.65mm).

Stock SS (or WS6) wheels are 17x9, 55mm offset, approx 7-1/8" backspace. Same bolt circle as above.

Maximum wheel width in the front is about 9.5", and offset should be in the range of 45-56mm.

Maximum wheel width in the back is 11", and offset must be 50mm (7.93" backspace). This wheel/tire combo may require some hammering of the inner fenders, and cutting the corner off the jounce bumper bracket - varies extensively from car to car.

Not sure if that answers your question....
