I used these Carrera IV wheels on my 928 and did have to roll the rear wheel wells, and was hoping to avoid that on the 911 C4.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

I wonder if we used the 35 or 30 series that geetee suggests if the rubbing would be mitigated?

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.

POST 1 / ORIGINAL POSTEROriginal post

I own a 1999 996 Carrera 4 Cabriolet fitted with 17" stock wheels. I have a set of 18" Carrera IV wheels from a 997.2 of the following sizes: Front: 8 x 18 et57 235 40 r18 Rear: 10.5 x 18 et60 265 40 r18 Can someone tell me if these wheels/tires will fit on my 1999 Carrera 4 without modification? Thanks, Gil

POST 2Original post

The wheels will fit no problems with width and offset you provided. Your front's may look a little sunk in and spacers will provide better looks. The only problem I see is tires. 997's have taller rear tires. The 996's have 265/35/18 rear tires. Being a C4, your F/R ratio is a little over 3.5% different which would be my concern. Buy them and get new rears with 265 35 18 or even go 295 30 18 which would be better on a 10.5 inch rim

POST 3Original post

I ran 235/40-18 on 8x18 50et and 265/40-18 on 10x18 65et for several years. But with the 60et and 10.5 rears you could have a rubbing problem.

Doug, I wonder if we used the 35 or 30 series that geetee suggests if the rubbing would be mitigated? I used these Carrera IV wheels on my 928 and did have to roll the rear wheel wells, and was hoping to avoid that on the 911 C4. By the way, I have seen conflicting answers on Rennlist about whether my 1999 C4 Cabriolet is a narrow or wide body. Comments? Gil

POST 6Original post

Trust me it's a narrowbody... widebody did not appear on the 996 C4 until the 996 C4S which is themed on the widebody 996 TT. There's not even a stranger things have happened possibility that it can be a 996 C4 widebody unless it is a C4S- which was NOT made in 1999.

GEETEE, You were right-on. I took the Carrera IV wheels off of my 928S and put them on my 996 C4. In bought new tires while I was at it. Front: 8 x 18 et57 225 40 ZR18 Rear: 10.5 x 18 et60 285 30 ZR18 On the 928S I had to roll the rear fenders; on the 996 all fit perfectly. The offsets with the tire sizes I used left perfect proportions front and rear. Nice aggressive look with the wide tires. Thanks for the input, Gil

POST 8Original post

Hi I was wondering if the original tires were actually ok? I am thinking about getting these exact wheels for my 996 c2, they will have winter tyres on them but the rears are 265/40/18 thanks for any advice

POST 9Original post

Does anyone see any issues with OEM sport design 10J x18 ET65 996.362.140.5 rears on A 4S Coupe using 25mm spacers ? Thanks Brendan
