GTO rims as DR

[gojo83]

Will the 17 in GTO rims fit as drag radial rims. I have a set on my gto parts car and if I could make a dedicated DR/slick and gto spare setup that I can cross use between platforms it would be awesome.

GTO's are 5X120 and F-Bodys are 5X120.65...GTO wheels do fit but be careful when torquing them down, I have heard people say they can crack or the lug nuts don't seat right. That was awhile ago since I read that so dont hold me to it but my friend did run a set on his Z before he got his ZR1's...They looked good and he had no issues.

As small as the difference may be (.65mm in offset), when you torque that first lug nut down, you're centering the wheel to that lug and stud. So your furthest away lug nuts are approaching being 1.3mm off center at that point. A lot? No. But, wheel studs weren't designed to have a lateral pulling force put on them, which is what you'll be doing to a degree because the stud won't be in the center of the bore on the wheel. This HAS caused failures in the past. Proceed with prejudice and caution.

I've seen people report on another site, over the course of the 15 years I've been there, that they have experienced broken studs and loosened lug nuts when running the 120mm bolt circle wheels. I always advise against it, as a licensed professional (mechanical) engineer. But for everyone that says they have had a problem, someone else will chime in and claim they have been "running the 120mm BC for years with no problem".

Fastbird hit the nail on the head from an engineering point of view. First conical nut centers, and every other nut has to either bend the stud slightly, putting it in bending rather than the pure shear it is designed for, or gouging a new surface in the wheel, perpetuating the off-center location.

Using them for drag radials, where they will be subjected to extreme stress, beyond what they would normally see with a street tire/street driving, would seem to be inviting a problem.

For as cheap as salad shooters are these days, it would be silly to be to run something not quite right on the rear of a drag car. Or, hell, old 5 spokes on pontiac cars would be just as cheap.

Kind of a off shoot for this but I was talking to a C6 vette owner and he said he hated the rims that are on it but I love them and I know the c5s bolt up no issue but I guess according to him the offset on the C6s are way off and you need spacers. Can anyone on here confirm or deny this fact? They are the skinny 5 spokes in chrome and I think with a lowered TA and the right spacer/ offset they could look killer.

This is the best pics/site I could find quickly of just the rim but I am sure if he just wanted to off load them 500 bucks and a trip to the state of many lakes could net be some slick show rims

Yeah, rears need like a 2" spacer, or at least 1.5" to look decent and run a c6 wheel. I almost got some from a friend but dont want spacers on the rear

Making you silky smooth...

C6 wheels on a 4th Gen:

What are called "spacers" aren't really just spacers. There are typically billet aluminum adapters, bolting to your stock studs and carrying a new set of studs to bolt the wheel on. These can be made extremely strong, and do not cause the bending stresses that would result from using long studs and a spacer plate. They are often used on rock-climbing 4WD's.

I've been running aftermarket wheels with the 120mm pattern for a few years without much issue. Like mentioned, you do have to torque the wheels in a slow progression. If you torque one lug before at least drawing the lugs against the wheel, it will be off center. With a correct fitting hub centric wheel, the lugs are not nearly as much of an issue as a wheel that is lug centric.

I guess this is a perfect opportunity to say YMMV.
