If i was to put a 4rth gen rearend in my 91 z28 could i put on 4rth gen zr1 wheels without spacers or would I still need them? I would like to put either 17x9.5 zr1 wheels or chrome zo6 wheels but didnt want to use spacers and my friend has a spare rearend from his 94 z28 that i could use. Just wondered if it would work and what it would look like because i dont want the wheels to stick out at all.

 

ZR1 rims+4 gen rear end= no spacers in rear

not sure on the Z06 rims though

 

Since all of the 4th gens with Z06 rims I have seen run them without any spacers, I would have to say they will work without spacers as well.
