Hey guys,

I recently purchased a new set of wheels for my Cayman S. They came of a C4S and I looked at the CEC website before purchasing the wheels and they said that 11in. in the rear will fit. However, what I didnt realize till now was that 11 in. cayman offset would fit not 11 in. C4S offset. I purchased the wheels with 315/25/19 tires (it came with them) hoping that it would fit. Without spacers, the tires sticks out of the fender by about an inch. I was wondering if there is anything I can do. If I went with 295/30/19 tires, do you think it will sit flush with the fender? Here are some pics. I really appreciate your input.

Sorry for the crappy quality.

 

If it's sticking out that much, then your issue is with the wheels, not the tires. You either need to machine the hub or get spacers.
Switching to a more narrow tire is only going to "rubber band" the tire around the wheel. It may reduce the appearance, but ultimately the wheel will still stick out the same amount.

 

Thanks for the response If i put spacers on, wouldnt it just make the wheel stick out even more?

 

Yes, I think you have an offset problem. I thought those wheels would work with the correct spacers, though. Do you have any more pics? What is the offset on the C4S wheels?

 

i have no idea what the offsets are on the C4S wheels.

I can surely take more pictures. What type of view would you like to see? On top of the wheel? side view?

 

WOW that sucks

 

C4S is widebody but Cayman is narrow, so the offset is wrong. There is nothing you can do except to sell it.

 

However, you can use the C2S one on a Cayman. Just need spacers

 

Wrong offset, spacers extend the hub out from the car, they will only make it look more jankey.

Some of you guys need to think before you post.

 

the difference between a 315 and a 295 is 20mm. But given the same wheel, the 295 will be 10mm further in on the outside and 10mm further out on the inside. It looks like it will be close to fitting. But you still may get some rubbing around corners on the outside fender liner. But here's a question - do you have spacers? If so remove the spacer and see if the 315 fits then. In general, our cars are happy with a 285 on stock rims even with a 5mm spacer. You should be able to shoehorn a 295, but a 315 is extreme. Also a 315/25 rides like crap and you are asking for pothole damage to your wheels. A 295 or a 285 will be a lot more sane.

 

Pull one of the rear wheels. If its a genuine Porsche wheel the height width and offset should be engraved on it. Knowing the width and offset should give us a better idea if there is a chance that it will fit.

 

I think that can work, if you really lowered the car so you have more camber, and running smaller tires for streched setup and that should clear..

 

Good call. I thought he was already running spacers...

 

I am not running spacers.. its sticks out that much without them, imagine how far it would be with spacers.

 

If they stick out that much without spacer best to find the correct wheels that will fit within your wheel well. Trying to get these to fit will only result infurther frustration. Believe me I've been there noy good, my two cents.
