5th to 6th gen fitment
 

Anyone know if the 18" 5th gen wheels will fit the 6th gen SS with the standard Brembos? I believe it's a 4 piston setup on the standard 6th gen SS? I'm curious if they will fit without a spacer, or if a spacer is needed what is the minimum size, and will there still be enough threads on the studs. Thanks

Did you ever get any answers to your question? I am looking for the same info, I am wanting a full size spare.

Never got an answer, but based on some recent events I'm thinking they won't fit.

I had the squared setup with 1LE wheels on my '14. I had 20x10 +35 on all 4's.
The wheels wouldnt work on the fronts as it hit the suspension.

Hope this helps.

Thanks for the response. I had some recent feedback that suggests these definitely won't fit

They definitely won't fit.

1st thing I tried was my 18" Weld setup on the rear where the tire circumference was the same as stock 5th Gen and it wasn't even close. (too big)

Yep that just helps to confirm it then. Thanks

I just re-read your OP and have to change my answer. :yikes:

The Wheels will work but the tires will not. I put shorter tires on my Welds and I did run them on a ZL1.

Here they are on with no spacers.
