rim/wheel question
 

does anyoe know if 18x8 wheels will fit all around the 986? thanks.

Don't suppose the Boxster design engineers
 

put different sized wheels on the car from the factory for a reason? Maybe handling, clearance, etc.

I believe they will but, I'm not sure why you'd want to.

i saw some aftermarket cayman wheels on ebay and the fitment was 18x8 all around and didn't seem to be staggered that's why i'm asking..

Well, they could have their info wrong, because the Cayman has a stagard fitment also. On the bright side, you could rotate the tires front to back with that setup, which would make them(tire treds) last longer. So if they really are 18x8 all the way around, you could just ad some wheel spacers to the rear to give back the cars clearance and turning radious. It has the wider stance in the back for a reason. Better tracktion and handling. :cheers:

Cayman / 987 wheels have the wrong offsets for a 986. Got to make sure you have the proper offset or you'll make an expensive mistake. The factory wheel size and offsets for 18" 986 wheels are:

Front 18x7.5 50mm
Rear 18x9 52mm

If you go 18x10 rear, the offset should be 47mm.

987 factory numbers:

Front 18x8 57mm
Rear 18x9 43mm

You could use a 7mm spacer on the front, but the 987 rears just won't work.
