Hi,
I bought a set of wheels for my 2005 987 boxster
I have 7mm spacers in the back

what is the correct bolt sizes that i need? I can't seem to find cone based nuts for 987 anywhere, does aftermarket wheels for 987 uses those 2peice ball base nuts too? Thanks in advance

 

If you add 7mm spacers then your bolts need to be 7mm longer.
The spacer kits Porsche sells come with all the hardware to safely attach them.

 

I actually bought the H&R 7mm spacers (for 987) through another dealer and I specifically told them that I need extended bolts for aftermarket wheels. Then it came with the ball seat bolts, they then told me those are the bolts H&R recommend for aftermarket wheels. Just wanted to make sure that aftermarket wheels for 987 uses ball seats. Thanks
