i'm planning to swap my 3rd gen rear out for a 4th gen rear because my 3rd gen rear is crapping out, so my question is can i just put my 3rd gen wheels on the 4th gen rear without a problem or would i need wheel spacers?

 

yes, but their gonna stick out about 1 1/2 inches outside the fender wall.

 

You only need spacers when going with 4th gen wheels on a 3rd gen rear. 3rd gen wheels on a 4th gen rear stick out like pasky described.

 

check the classifieds. there's a guy selling the rears and wheels, too.

 

if your panhard bar is centered on your car, the tires come right TO the lip.. not beyond, but to it.

if the bar is off at all, you may have to roll a lip on one side or the other...

 

he's right, except that when i put my my wheels on, the tires never really came close to scrubbing. they just stick out. it's an appearance thing, not fitment. although, i would say it's a good time to think about some custom wheels. get em cut for a 3rd gen front offset, and a 4th gen rear offset. you'll wind up with like a 0mm offset rear, and like a -37mm in the front, but I'm not positive on those measurements. (no pun intended) the cool thing is, you can go significantly wider with your rears.... 305's, anyone??

 

305s? HA!


you can fit 315s back there.

a friend of mine just put 17x11 rims on his 99 camaro... next time he pulls one off, im going to test fit it on mine... :lala:

 

I thought you could... but I KNEW you could put 305's on. I'd like to see if it's possible to stuff 345's on the back.... damn that'd be huge, though.

 

nope.

at that point, even with a flared and rolled fender, you would have to SERIOUSLY modify the inner fenderwell.

 

so if i do a swap like htis, whats the biggest tire i can put on the 4th gen rear on a third gen chasis, 315 maybe....on a 17 inch by 10 rims..or 11.....

 

same size as the biggest you can fit with a 3rdgen wheel.

the size of the wheel well isnt changing.. only the offeset needed to keep the tire centered.



largest that can be wedged in there with only minor tweeking is a 315 series tire.... that would be on a 11" wide rim.

 

sorta. if you don't care about centering, I honestly think you could go bigger, provided you're using low profile tires. a 17x11 or 17x12 would be the answer.

 

I wyould say a 315/40/17 would be the biggest you need anyway. much bigger, and you're talking drag slick territory.

 

that fits in the wheel well with minor work.. mostly you just tap one bump on the inner fenderwall, and/or possibly roll the lip. depending on your exact offset.

 

so it's not much of a problem.... good to know. I'm going with some WS6 wheels, or a custom set (haven't found what i like yet). who makes the best adapters for the front? transdapt seems to be cheap quality, but skulte looks like he has good stuff. what about f-body motorsports?

 

so 11 inch rim, i can do the wheelwell easy, tahts not a problem, i work at a body shop, but what rim comes in 11 inhes wide that fits a 4th gen rear, Zr1's or what...

 

factory? i only know of ZR1s... other then that, you're looking at aftermarket rims. and ofcourse aftermarket means any offset you need.

theres a bunch of used 4thgen aftermarket rims out there if you look too..

 

do they have ZR1's or even good kockoffs that fit 3rd gens?

 

sure. you can use bolt on spacers to make up for any diffs. so you can run real ZR1s, or knockoffs... they make some in 3rdgen offset, but they're really narrow... kinda stupid really, the whole point of ZR1s was that they are wide.....
