Does anyone know if a 10.5" rim backspaced for a C5 would stick out as far as a GS offset rim or a ZR1 rim?

Thanks
Jim :steering:

My feeling is that they wont because I belive the offset is in the sixty something mm range. It would be nice to know for sure so if anyone out there is running 18x10.5 let us know how they fit.

Are you speaking of a stock C5 rim on an 88 and up (not ZR 1 or GS)?

If you are, the wheels do not "stick out" They fit just like original

:seeya

Thanks Jack! :auto:

hammer,
Kevin has my C5 wheels. Give him a shout.

....I need to stop giving him free stuff:lol:

I am not too sure about the 10.5" but I have the 9.5" Y2K's and they are the opposite. Sort of "tucked in". They still look nice.

Hammer, we'll have to meet up at one of the corvette challenges at Englishtown next year. I'd like to see your car. :yesnod: :cheers:

HeyJim.....

I think the 10.5" would fit it perfectly.... I havent gotten the C5 rims on my car yet.. but everyone else says they tuck under a tiny bit... So the etra inch prolly puts it right where it should be :thumbs:

Coming down the the finish line wiht that thing... Cant wait :steering:

On a later C4, they fit perfectly! :D

I am running 18x10 in the front and 18x11 in the rear. My wheels will bolt up to a Z06 without issue and do not stick out on the 89 C4. You should be OK.

Good luck,

Ron

Thanks for all the help guys!

Jay, I went to one challenge last year, I'm going to more next year. I may even try and compete.

Kevin, It's coming close, You know it's too long when your dreaming about it. :crazy:

Lspalding, Tell me about your 383 setup!!

RonRed89, tell me about your 396!!

Here's a pic of 'zelements' car with 18's all around.

Looks sick.

chaos on wheels

The OE C5 wheels are 18x9.5" on the rear. OE Z06's are 18x10.5" on the rear (offset= 58mm). I've got rear Z06's on the front and back.



They fit fine with 295's on the front.


But they rub a *little* on the back (also with 295's). I've just never got around to bending or removing the splash shield. The tire doesn't hit anything else, just the splash shield.

There is plenty of clearance on the outside of the wheelwell so I might get a slim (~1/8") spacer. But the rub isn't bad enough.

Hammer

chaos,
Thanks for the info.

I originally wanted to go with 10" fronts and was thinking about going smaller.

After seeing your post, I'm holding out for what I want.

If there is such a thing as standard, it's your "standard" MORE Performance 396 bottom end (Callies 4340 crank, Lunati Pro Mod Rods, Custom J&E Pistons, coated bearings and pistons, Oliver Billet Splayed Mains). The cam is going to be a Crane 222/230 112LSA hyd roller, valvetrain is all Comp Cams. The heads are AFR 195s race ported, and the SR manifold is ported and matched. Other goodies include a new DeWitts C4 radiator (Thanks Tom!) and RaceTronix fuel pump. The trans was rebuilt and I added a Vigilante 2800 TC. Car is almost done, but a pesky MAF tuning problem has stalled the completion date. Since it's winter now here in Ohio, MORE has as much time as they need to complete. It's looking to be a hell of a car once it's done. Unfortunately, I'll have to wait until the Spring before I can have any real fun. Hoping to see about 520HP at the crank with these mods.

How is yours coming? I know that it's been a long time in the making for you too. I haven't had my car running reliably now for 2 seasons. This build will change all of that I'm sure.

Back to the wheels, you might want to consider going custom (CCW, Simmons, HRE, Fikse for example). You eliminate a lot of the potential issues of rubbing and fitment as you can get exactly what you want made. My Simmons were custom made as are all of the Fikse/CCW/HRE etc.. and I haven't had a lick of trouble with them.

Good luck,

Ron

RonRed89

Man, I REALLY love this car. Those Fikse's are the absolute best looking wheels on a C4 bar none. (IMHO) Too bad it takes about 4k to get a set.

It's been down for over a year, finally coming to an end now... I was planning on using a custom wheel when the time came, but a set of Fikse FM5's from a C5 are available. I'm going to pass and wait until I have the money to purchase exactly what I want.
