Thickest wheel spacers on a 996?

Recommended Posts

Hi, I drive a 1998 996 narrow body with 285 tyres on the rear. I'm thinking about spacers merely for appearance, to widen the track. I believe Porsche officially only reccommend up to 5mm all round with this tyre size, but what's the thickest anyone has, that has not affected performance in any way???

Subtle, but still noticeable. I didn't take any pics of the rear though. Somebody over on Rennlist though posted pics of his 17mm spacer on the rear runnning with a 10x18 rim and 285 rubber. STUCK OUT! Didn't look good. My suggestions is either the factory 5's or aftermarket 7's.

I have settled on 6mm all round with GT bolts and lockers. They look great, flush with the arches now. I tried 9mm and 18 mm before but the 18s stuck out too far and the 9s didn't work because the wheels would not centralise mainly because the spacer took up all of the central hub that the wheel usually locates on. It felt like running on oval wheels.
