I have recently purchased a set of Shaper rims for my 2003 996 C4 and need advice on what size spacers to purchase. The fronts are 18x9.5 65mm offset and the rears are 18x10.5 60mm offset. Tire sizes for the fronts are 225 40 18 and the rears are 285 30 18. I was told they would be bolt on and they are definitely not the calipers scrub and the fronts touch the coil springs. I would like to know if there are spacers that would work (what size I need) and would they be safe.

Currently running 10.5" x 18 / ET60 with no issues on a C2

No fitment guide that I've seen shows a 9" wheel for the front of a C2 or C4
but that doesn't mean no one has done it

Quality spacers at reasonable pricing can be found here

I suspect that the 'stepped' design of the wheel might be part of the problem

 

looks like stock suspension? 23mm front spacer should do it. I know on aftermarket coilovers, 9.5 wide 42mm offset will work.

 

thank you for the response I appreciate it sorry I've been out of town in sick so I'm just seeing the responses now . Yes I believe the suspension is completely stock I was thinking about ordering 25 mm spacers for the front as far as the rear do you think 25 mm spacers will work as well ?
