If I put a 4th gen rear in I can run any rims I like with no spacers? sorry if this has been asked but I have a 2002 SS in my yard that is a theft recovery. I can bull the rear before I scrap it

 

You can run vette and 4th gen wheels without adapters. But the rear end is stronger and depending on your gear it will probably be a step up there too. Keep the rear for sure.

 

gearing, maybe, but his 91 will have 28 spline axles too, so no difference in strength.

 

Thanks I will pull it, there nothing left but the basic shell

 

As mentioned, it's still just a 7.5 10-bolt. No stronger than anything else.

HOWEVER - it may hve the Zexel Torsen posi carrier which is super rad. I'd love to have a 10-bolt with a zexel torsen! So if you junk it at least pull the axles and pull the carrier out of it.

 

Well it looks like the only only real difference is that the rotors on this 4th gen have a built in spacer, the rear ends are identical. Is this what allows you to run 4th gen wheels on a third gen car, just checking.

 

I'm unsure of what spacer you're referring to. Have a pic? The fourthgen rears are, of course, a bit wider.

The unit its self looks to be the exact same size, i need to measure it, when I lay the two rotars sisde by side the fourth gen is taller

 

Any pics? Your rotor description sounds like a rotor with the adapter still on it.

 

I will need to snap ome tomorrow, but the rotor is factory or aftermarket, no adaptor that I can see

 

Okay maybe it is just a heavier duty rotar, question is I can run the 4th gen wheels on the rear and front with no spacers correct?

 

with both rears side by side, axle flange to axle flange measurement on the 82-92 car is 61.72” and the axle flange to axle flange measurement on the 93-02 car is 64.72”.

Yes it was, I was also looking at your pic's, I will be running 4th gen wheels so I will not stick out (though I do like the look) Lots of good info. I measured mine just because I heard so many differant sizes at every way I turned
