Default This is for you Z06 REPLICA wheel owners!!

Just got my Z06 motorsports and I don't like the backspacing and offset, the wheel/tire is too sunk up inside the fender. My other 17x9.5s fit almost flush with the fenders but not these. Anyone using any type of wheel spacers to solve this issue? I am thinking 1/4" or 3/8" wheel spacer would help a lot and could still use the stock studs.. What you guys think? THis is on a lowered TA so it looks REALLY phucked.

I've used a 5/16" spacer before with stock wheel studs. But I would not recommend it for very long.

For a 5/16 spacer I'd put longer studs in. I've got 1/8" Iroc spacers on the rear of mine and they fit fine b/c they're not very wide at all.

This car is not a daily driver and never really gets pushed hard around corners(DRs) it pretty much just gets cruised around, car shows etc and maybe a little street racing. I am gonna pull a wheel and see how much stud length I have.. I really want to space those wheels out...Looks kinda cheesy right now. My other wheels were also 17x9.5s but they fit PERFECT:

ya I stuck the 5/16" spacers on and it made a tad bit of difference but not enough to risk the safety. These wheels really need 7/16-1/2" less backspace to make them fit right. I could do a 1/2" spacer w/ some long studs I suppose..What a pain in the *** though.guess I am gonna take these 5/16" spacers back.

ALSO I could only get 1-2 turns at best on the stock studs with the 5/16" spacers in. I will get a pick for display only but..Not leaving it like this.

Here is the pics of the side with NO spacer:







Notice how far the wheel is buried up in there.
Here is the pics with the 5/16" spacer installed:







YES it is better but it still needs more..In reality, these wheels need 1/2" spacers and 1/2" longer studs to fit and look correct. I am thinking that is what I am going to do. I found a place with 7/16" spacers but no 1/2". Gonna keep looking.

This is just something for ALL of you guys wanting to run Z06 Replica wheels. The wheels do look awesome and are of very high quality..just wrong spacing for F-bodys

I see that wheel spacer on the ground. I think those are the cheapo crappy kind. You need hubcentric ones or else you will have vibration problems, unless those ones you have center up nicely, do they?

Ferocity, they were the cheap Os... They didn't line up worth a damn. I didn't drive it because I only had about 2 turns on the lugs but..I wouldn't use em. I guess I am going to do what everyone else does and live with it but...it really annoys me. Every F-body I look at with Z06s or ZR1s I will now be watching for the sunkin wheel problem. These things fit/look like the factory 16x8s from the outside.

Those spacers you are talking about? where can you get em? $$?

Ferocity, I am not sure what the offset is, I thought it was 54mm also. Mine are definetly tucked in more then yours. I am thinking of getting the 7/16" spacers and longer studs and trying it. Do you think I would get vibration problems even since the wheels are lug eccentric and not hub eccentric? meaning since they are aligned/center by the acorn lugs? I think the main safety issues with the spacers are the fact that people use the short studs and not near as much threading holding the wheels on.

He's talking about hub-centric adapters. They bolt to the hub, and the wheel bolts to them. They are more expensive, but much safer. You can get them much wider then spacers, 25-30mm.

Ya I have seen those...thats WAY more then I need. I only need a total of about 10-12mm or around 1/2". Those adapters are pretty trick but I think I will try my cheapies, 7/16" and 1/2" longer studs. Not to mention you would see those big adapters behind the wheel since you can see right through a Z06 wheel.

Thanks for the link though!

are you pounding the studs in/out with a hammer,or do you have an impact gun---- also are you doing it with them still on the car???

WEll I haven't done them yet but I am planning on leaving them on the car and knocking them out with a hammer, then using an open end lug nut and an impact to suck the new studs in. This is the plan anyway. I know its gonna be a pain in the *** but...I gotta get this fixed. I will not be satisfied with this wheel purchase until I got it right.

You will not get vibrations because of the wheels. If the spacers arent hubcentric then they may not be properly centered when installed, which will cause some nasty vibrations.

He's talking about hub-centric adapters. They bolt to the hub, and the wheel bolts to them. They are more expensive, but much safer. You can get them much wider then spacers, 25-30mm.
There are hubcentric spacers out there, not adapters. I dont know where to find them. You are right though, the adapters are very safe to use, but also very thick and expensive.

are you pounding the studs in/out with a hammer,or do you have an impact gun---- also are you doing it with them still on the car???
I belive to install the studs you just put the stud through the hole and put on a nut with a washer and tighten away. You should have some moly lube on the threads so you don't start ripping threads off the studs. If you use a hammer then the studs might not be installed straight. You could certainly install the studs with the axle on the car, but taking them off is a whole different story. If I were to do it, I would take the axles out of the rear and take them to a machine shop to be pressed out. They should also be able to press the new ones in, all for around $20-$30. I would do a search to find the proper way of installing longer studs.

yeah,I really don't think banging them out with a hammer is a good idea...if you have an air chisel it would be better to remove them that way...by forcing them back out,not cutting them...good luck..

ya its gonna be a major pain in the ***. No doubt about that. Definetly knock the studs out with a hammer(hopefully) and then use a nut and an impact(after its started by hand) to pull the studs through. I don't want to fool with pulling axles. I just changed my rear end fluid about 1k miles ago. I was hoping I could do them on the car without pulling the axles. Maybe the longer studs won't be able to start through the back of the axle. no room.. Not sure.
