Silver c6 z-51

Hey forum members, I noticed that my 05 driver's side rear tire is about 5 mm inside the rear quarter panel lip while the passenger side is flush. Is there an easy way to adjust the rear cradle for this or should I not concern myself, tire wear seems to be even on both sides

I don't believe it is possible to adjust this?? Possibly CV is out of the Diff??

There is a pin to align the rear cradle so that can't be adjusted. My car is off by that same amount as well. I believe that is just the way they are.

I would not worry about it, but it is more likely that the fender is slightly out of place then the rear cradle anyway. Body panels have lots of positional adjustment.

Remember also that 5mm on one side could mean that one fender is 2.5mm too far in and the other is 2.5mm too far out. There's no reason to think that one is perfect and the other is off by 5mm.

This has been discussed before and most seem to have the same problem.

Mustangs apparently worse, or so I have been told by a local speed shop.

I went back to stock tire size due to this offset. 305 rears stuck out to much on the passenger side while the driver side was flush.

Look around at any C6 you come across and I think you will find this discrepancy frequently.

I think the problem is called "stacking tolerances".

Think about parts manufacturing tolerances of + or - 0.05". Get them all to line up + and there will be a misfit even though all parts are within the tolerance limits. If one side is all + and the other side is all - then you'll have a real obvious problem.

Get a 5mm shim for the wheel that's short, you won't even have to change lugs for that small of a difference.

Don't sweat it. Mine looks like that too; don't know if it's 5mm but there is a tiny amount of difference.

With mine it was only noticeable when I ran the 305 widths. Stock 285 is not easily detected.

Mine was the width of the tire bulge on the sidewall from the tread outward.

What mm who knows.

Not quite as small as it sounds. The universally accepted safe thread engagement being equal to the thread diameter, a 12mm x 1.5 stud requires 8 full rotations of the lugnut. So assuming stock wheels and lugnuts that already require 8 turns of engagement, any spacer whatsoever puts safety in question. Since stock lugnuts are not full threaded, purchasing aftermarket ones would be advised. Unfortunately, the additional thread engagement for full threaded lugnuts only is capable of compensating up to 3mm, which means a 1/8" spacer is the maximum.

I think this is correct from what I can recall when I researched my issue. I eventually went back to the stock tire width. Now the discrepancy is not noticed as readily.

I have never liked the idea of shims in regards to wheels.

Any additional/new suggestions on moving my 12' Grand Sport REAR CRADLE 3mm to the Left
(toward the drivers side) or NO it wont move ?????

Not going to move.
