I saw the car for the first time today. It looks great. However even with the 5mm spacers fitted it seems like the front and rear wheels don't fill out the arches the way I would like them to. I think as much as another 10mm could be used front and rear which would mean a 15mm spacer. RSS makes spacers for the 997 in this size which are available in black with black bolts and it seems there should be no issues fitting these to a 991? Has anyone installed after market spacers yet on a 991 C4S? If so would size did you use front and rear? My car has PDCC + PASM. I'm not looking for nor suggesting there is a performance advantage in fitting the spacers, this is purely driven by aesthetics.

 

out of context question: will the new turbo have the same exact dimensions (width) as the c4/c4s?

 

I have 14's on all four corners of my 996 and that is about perfect. They also helped get rid of the under steer common to The 996 TT.

From your pictures, I'd say 10's would be just about right. 15s might take you into ricer territory.

 

I just installed 7mm H&R with extended lug bolts. Really helps clean up the well area.
Where do I get Black lug bolts ?

 

991 and 997 use the same spacer and bolt pattern. So you can use it on the two cars.
I bought a set of 7mm and a set of 14mm on Ebay with the extended wheel bolts for $155. they work fine.

 

Thanks. I'll shop around knowing that I can order lugs that fit the 997
