Spacers and Springs

[Boca996]

First, congratulations Loren on your new website! :cheers:

I have a 2002 C2 Coupe and am considering installing H&R springs. Can this be done if I want to also install a set of spacers and if so, what size? Is anyone aware of any negative feedback on spacer installation?

Thanks!

Spring spacers or wheel spacers?

If I may, there is a greart article on Porsche tuned suspension in PCA Panorama. IMHO I think it is kind of a required reading before making any major decisions on suspension changes. You can find the article at: 996 Standard and Sport Suspensions Analyzed

Sorry for the confusion and this is an opportunity to give you some more detail I think you might need. I have Carerra 18" 5 spoke wheels running 285/30s on the rears. I was planning to lower the car with H&R springs and was also considering wheel spacers (not spring spacers).

I am not a big fan of changing one suspension componnet without change the other affected parts (i.e shocks, bumpstops, etc.). So, perhaps you want someone elses opinion? ;)

If you want to lower the car that can be done with just spring changes but anything lower than 3/4 to 1 inch will make the engine block more vunerable to damage (high curbs, rocks, etc.) and you may have some problems with fairly normal driveways.

Porsche sells and recommends two wheel spacer combinations. The first combo is four 5 mm spacers on all four wheels. This is sold as a kit that includes longer wheel bolts and longer wheels locks. All GT3's use these spacers. The second option is 5 mm spacers on the front and 17 mm spacers on the rear. If you ever have to run the spare tire the 17 mm spacer must be removed to mount the spare (the 5 mm are ok).
