I have an 89 Firebird Formula. I picked up a set of 245/50/r16 bfgoodrich kdws tas and now that i have them I have decided to get new wheels. I know that the wheel size is 16x8 but about the backspacing and bolt pattern no frickin clue lo. Is the bolt pattern something like 5 4.75? Is the backspace 4.45? I hear different backspace on front and rear is this true? Please help, this sh t has been bothering me, Im almost about to slit my wrists. THASNKS ALOT!

 

This is what it says in the FAQ section.

Q: What are the offsets for the front and rear 16 inch wheels?

A: 0 mm on the front and 16 mm (negative - outward) on the rear.
