Factory C6's?

**WS6ICK2K** · 03-21-2008, 08:36 AM

I have found a set of factory 18s and 19s that have been chromed and look brand new for $600. I was wondering if I would need a spacer for the back since they are 18x8.5 front and 19x10 rear, and what size tire I would need not to have an ABS light on. I was thinking a slightly taller tire since I will not be able to rotate them. All info would be greatly appreciated.

Thanks,

Ryan

well you need to keep the tire height as close to stock as possible...with 19x10..you would only be albe to go up to 295s(thats pushing it) ...i'm not sure on the spacers..i dont believe so

1.25" spacer will be required to run the 19x10's on the rear. I run 275/30/19 tires on my 19x10's, but I'm running them all the way around. IF you're going to stay with the 18x8.5's in the front, I'd recommend a 255/35/18.

what is the offset of the 19x10.5 ?.. is it the same as the 18x10.5 ?
If so, I'm running a 1/4" spacer in the back and I'm good. Offset on a 18x10.5 is something like +56 or +58mm (from memory)

The OEM C6 19x10 has a 79mm offset requiring a 1.25" adapter to run it on 4th Gen. F-Bodies. The C6 OEM 18x8.5 has a 56mm offset and will fit the front of the 4th Gen. F-Body without any kind of spacers...but they're a little close on the rear.

I mounted the 19x10 just to see how much of a spacer I would need and just the rim is about 1/2 inch fron touching the inside of the fenderwell. So Ill see when I get my tires how it fits, 275s in the rear probably.

BandDirector do you have any pics you can post up of your car with the 19x10s all around?

Your car looks great, low and mean. I actually decided to return those 19x10s they were from a local GM dealership. Instead I ordered a set of C6s 18x9.5 to go on all 4 corners along with 275-35-18s. I figured this would be the best way to go. I did some research and I think 18s are about the max for an f body and I didnt want to use 1.25 spacers.
Eugenio it looks like to me you have a pro kit, just wondering what shocks you decided to go with?

thx 4 the compliments.
Prokits are in some pix w/ the ZR1s... I no longer have the prokits, but have Ground-Control Coil-Overs. shocks are Koni DA on all corners.

I still haven't repainted my calipers or installed my EradiSpeed rotors, so all I've done so far is a test fit and test drive around the block. BUT, I did take a couple of test fit pics and you can take a look here:

Where can I get spacers?

**BandDirector** · 03-30-2008, 09:41 AM

I got mine off of eBay...you can get 1.25" spacers for between $55 - $65 shipped and if you buy 4, you can do just a little better.

factory wheels will go on. you will need to seriously clearance the inner fendewell on the rear, to not use spacers. looks too far tucked in though. so, a 1" spacer for the rear would do nicely.
