I have been talking with Terry at Wheel Smith, a very knowledgable guy about my situation. All in All I have decided to go with the stock C4 front brakes!

This eliminates a lot worry about steering problems, opens up my wheel selection and I can run all 4 the same!

Chip,

Before I order any rim I want to make sure I understand what you are saying you ordered for your C4 on four corners rims?

16 X 8 rear with 4.75 backspace?
16 X 7 front with 4.75 backspace?

I have decided to go with stock C4 on all four corners considering that both vehicles weigh in at about GMC 3150LB curb / Corvett 3293 curb
close enough for horse shoes or dancing
And it open up my wheel selection wide open!!!!

Have you mounted the rims yet, checked them for fitment?

Are you an earlier or later gen C4?
Mine is an first gen 84, which stock has the exact wheel on all 4 corners.
If you are looking at the later gen, stock might have been different size front to rear with different offsets. I don't know what year your Vette suspension is from. The only reason I went to 16 x 8 with the 4.25 backspacing as my rollers are 6.5 wide with plenty of space, and the widest others have put under these trucks with these suspensions was noted as 8". I may have gone too wide, but all the wheels are identical to keep the footprint equal.
With medical issues happening, the only thing I've done is dry fitted the wheel alone on the rear with the fender hanging on the bed last fall. Talked to my tire guy today to say I'll be down in a couple of months with one wheel and a list of tire sizes to keep height required. I might have to order new narrower wheels if they are too wide.

My research shows me all C4 84-87 ALL wore the same size wheels front and rear
which is what my choice was from the oneset to go with the 84-87 suspensions.

I may just go with 16" x 7" on all four corners and run my spare!

I want to thank all for getting me back on point when it comes to steering
geometries!

If when I assemble all body parts and I'm too tight in spots, that's probably what I'll have to back size to....16 x 7.
I shoulda gotten one of those wheel offset and size measuring tool that some have been talking about lately.

I returned mine and got my $ back from Speedway!
Did not care for it!

Ordered a test wheel from Wheel Smith, should be here any day now!

I went back to stock C4 front calipers and rotors with the hopes of running all 4 wheels the same size.

Will Post up an update after I test fit the rim and if that go's well, I'll
figure out what tires to run on my 16' X 6" rims
