I am looking to use these 5th gen Z28 wheels on my 91 Z28 show car.



My car will also be painted white. Not GM white as shown, but an Audi white that is much brighter.

I would run 20"x11" in the back and 20"x9" in the front. Brushed finish.

What do you think a good tire size would be for 20" rims? In terms of width I think I will go with something like a 315.

My last build up of this car was running 17x11 C4 GS rims in the back. No mini tub. Now I am minitubed with a Moser 12 bolt.

 

Based on the link they only come in 10" wide for the rear. A 305 width would be perfect on a 10" wide wheel. The main problem you'll have is the bolt pattern. 3rd gens are hub centric on a 120.65 mm bolt circle, not 120mm (5th gen and 6th gen but ironically not vette). If your Moser rear has 1/2" wheel studs they won't bolt up at all.

I also think the hub diameter is smaller than the 70.3mm on our cars.

 

Z28 wheels are 19", not 20". They are meant to fit a 305 width tire.

 

Here is a link for the 11" wide rears:

I had no idea about the bolt circle shiftycapone, I will have to figure out a solution. Maybe 5th gen axles for the moser rear. My studs are not the 1/2" size.

As for the front I will be using Bear Pro+ billet hubs, maybe they can adjust the bolt circle. Not sure.

Or I just find another wheel to use I guess.

Paul_huryk: Not sure what you are pointing out. The rims I posted are Z28 knock offs, not legit Z28 wheels.

 

Just found these when confirming the info posted above about the bolt pattern.

I figure I will need to use spacers, so this might be another route to take.
