I've decided to stick with my Carrera S wheels on my Cayman S. I am running 275/35 rears. I would like the fitment to be flush with the fender, without any rub. Has anyone done this with these wheels on a Cayman?

 

Chad 987 It's easy enough to figure out , take a straight edge just long enough so it will touch the tire top and bottom center and the wheel well, then measure how much space you have between the edge that's touching the tire and the metal subtract 1mm that will be your spacer. Then you need to make sure your lugs are long enough or you can opt to go with studs and nuts.

 

Install your wheels. Then decide if you need 7mm or 15mm to move your wheels out to where you want them. There may be other sizes but those are the two I'm familiar with.

 

i am running 15mm at the rear and 7mm up front with OEM 19"s 265/35-19.
they sit pretty darn flush, no rubbing.

 

most spacers for OEM wheels will be 5 or 7mm up front and 14-15mm for the rears. Dont forget the longer bolts to go with it.
