1997 Boxster 18 inch Rim fitment Question.

[RandallNeighbour]

My 18's require 5mm spacers, but this may have as much to do with the fact I've lowered my car all the way around via my coilovers.

I say this because my 17's also require the spacers.

As far as offsets go, the front is an exact match.

The rear should be 47, so according to the 1010tire offset calculator, a 55 offset will move the wheel IN 8mm.
