C6 Wheels

[HQuakers]

Ok, I searched but didn't get an answer to my question. I know it's been beat to death, but here goes:

I am looking at getting some C6 Motorsports or C6 Z06 replicas. They will be 18"x8.5" ALL AROUND. They have a +56 offset, and I have 6mm spacers, so essentially they will all have a +50 offset with spacers. My rear fenders are cut, so no lip there, and I have drag bags at 7-10psi. I will be putting my 245/40/18 Nexen's on these. Putting the bolt pattern aside, will I run into any problems in the front or back?

Cliffs:

Size: 18"x8.5"
Offset: +50
Tire Size: 245/40/18
Rear fenders cut
Drag bags at 7-10psi

Will it fit?

Gracias.

I ran a 18x8.5 front, 18x9.5 rear C6 motorsport setup for some time. I had 235 in the front, 275 in the rear (BFG KDWs). I just sold my front spacers as a matter of fact, I've actually forgotten what they were thickness wise. I had zero rubbing with that setup, the rear fit perfectly as those Corvette wheels have a deep inside offset, not a goof looking outward offset like many here run. They cleard the fender no problem and I had no modifications to anything.

Can we get a shot from the side?

[smokehouse]

Sure...

Here's another rear shot...those were 275s in the back, no clearance problems:

what all do we have to get to mount som c6 wheels on our cars. i've read alot and am in love w/ the look. i just cnt remember what all i need. and search doesnt work from here

[wickedgto8]

Dude not to be off color or anything but don't put vette wheels on a Goat!!!

[ALester38]

Don't think you will have a problem in the rear, but the front will be really close to the strut if not touching it. The stock wheels are already pretty close to scrubbing tire on the strut and putting a wheel with more possitive offset will bring it even closer.

What are you going to do about the incorrect bolt pattern?

[BLITZD247]

I was just searching ebay today and came across this gto for sale with vette wheels. pictures give nice angles and the wheels look nice.http://cgi.ebay.com/ebaymotors/Pontiac-GTO-LS2-06-GTO-LS2-6-0L-V8-Loaded-Xnice-Leather-Chromes-Fast-TX_W0QQitemZ280310554260QQihZ018QQcategoryZ7244QQs sPageNameZWDVWQQrdZ1QQcmdZViewItem

Do a search on that one...the difference in the bolt pattern is less than the thickness of two business cards...most wheels don't even have a tolerance that tight on the bolt holes.

The pattern on a GTO is 5x120mm, on a Vette it’s 5x4.75” or translated to metric, 5x120.65mm. That means it’s off by .65mm or .025 of an inch.

[wickedgto8]

meh... why not? More than half the forum (including yourself) has BMW spec wheels!

OH!!! I did not know that I had BMW wheels bro! Hey could you show me a BMW with wheels like mine and that looks as good as mine??? I seriously dought it LOL!!!!

Go for it man! Love the C6 Wheels!

If you read what he said he said bmw spec. I gotta say though your car does look sexy very very sexy. Oh and to the op go with the C6 wheels they do look good I personally wanted Z06 wheels for ever changed my mind about 60 times already. Good luck with whatever you do.

The difference is small, but it does matter. If you take a wheel with a Chevy bolt pattern and conical seated lug nuts and mount it on the GTO, you will see how the difference prevents the lug nut from seating properly on the wheel. Turns what would be a face-to-face contact in to a point-to-point contact.

Machining tolerances are an order of magnitude smaller than 0.65mm.

Wheels look great!!!!

That was my next choice!

[HQuakers]

Since I'm trying to find wheels that will bolt right on, the Vette wheels aren't going to work for me. I am getting rid of a set now that need spacers, so I'm probably going to bite my lip and order something from VQ that I know will fit and don't need obscenities thrown about when trying to mount them, heh.

Thanks for the help everyone.

Depending on your tire selection you still might have to roll/cut your fenders even with VQ wheels. If you want true bolt and go, CCW, HRE, and Foose can accommodate you.

Fenders are already cut with 7-10psi in the drag bags :-pimp:

There's no way in hell most wheels have tolerances that tight on the bolt pattern...come on, 25 thousandths of an inch? No way...possibly on serious racing wheels but on your common run of the mill wheel, not happening.

Add to that the fact that put my car into a curb going 50, managed to warp or crack all 4 wheels they didn't fail ( I shattered the front driver's side and I didn't even bend one of my ARP studs)...I can tell you from actual driving experience that running Corvette wheels is 100% safe.










*EDIT*

And yes...I know how much .025 is...I was a machinist for years and worked with tight tolerances all the time.

awesome car, and I like what you did with the GTO lettering.

[Fuelie Fan]

This is not wheel specific, but just about the sloppiest tolerance we call out on any machined part is 0.030, so 0.025 is pretty loose. Presumably these wheels are cut by a CNC machine nowadays...I would hope they are holding 0.010 true position or else they should get a new machine.

[red5.7gto]

the red goat is sick. THey don't look bad at all.

[greenday1031]

if you run 245/40/18 in the front how big with cutting can you go in the rear for a nice fat sidewall??...any abs issues?

Yes, the clearance on the through-hole is greater than .025", but unless the wheel was whittled with a carving knife, the positional tolerance on the hole had better be tighter than .025". The position of the hole (or more specifically on these wheels - the conical seat) is what is determined by the bolt pattern and what is important.

Either way...we can debate tolerances forever...

In my mind, the proof is in the pudding. I ran them for over a year no problem, they even withstood a nasty accident...no matter how you look at it, my was was working proof that GTOs can run Corvette wheels with no issues.
