Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Actually, this is great news; I always thought the wheel wells needed to be filled a little bit more on the 996 C4S/Turbo.

Since the rear is way high for a GT2, I suspect I will not need to roll the fenders, but I'll be sure to check after install.

But the filling of the fender isnt the problem with a 12 in wheel, they may scrape the fender lip when compressed all the way.

Or used the GT2 size and offset for a 2S/4S?

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Since the fenders are the same for C4S and the GT2, I'm guessing the wheel exchange will not require any modifications, though I suspect the height of a 315/30-18 - 235/40-18 set (my C4S is 295/30-18 - 225/40-18) will cause a slight speedometer bias. Has anyone done this? Or used the GT2 size and offset for a 2S/4S? Thanks

POST 2Original post

GT2 rear fenders are rolled, but if your car hasnt been lowered, it may not require it done. If your car is lowered, it may or may not need to be done.

POST 3 / ORIGINAL POSTEROriginal post

Thanks: I have the Euro front springs and struts, and the US rear springs and shocks, for what I consider to be the best compromise between sport and comfort. Since the rear is way high for a GT2, I suspect I will not need to roll the fenders, but I'll be sure to check after install. Actually, this is great news; I always thought the wheel wells needed to be filled a little bit more on the 996 C4S/Turbo.

POST 4Original post

I have row C4S springs F&R and the rears still arent as low as the GT2 looks to be. But the filling of the fender isnt the problem with a 12 in wheel, they may scrape the fender lip when compressed all the way. They had to have a reason that they rolled the GT2 fender.

POST 5 / ORIGINAL POSTEROriginal post

Yes: I will call my body shop and arrange to have the fenders rolled prior to GT2 tire/wheel installation, just to be safe. Thanks again for the heads-up.
