The way I would like to do it is to go conservative on the outside clearance and space the wheels away from the springs if needed. This is why I thought +19mm would be acceptable because IMO, a 5mm - 15mm spacer is completely acceptable with longer studs. On the front, I already know the stock Boxster 17x8.5 rears with +50mm will barely fit in the front and clear aftermarket coilovers so I know a theoretical +31mm should work with the 10" wide wheels.

Thoughts?
Seems plausible . A +50 et up front with an 8.5 inch wheel will leave about 3mm's of clearance from the strut. So that's way too close IMO.
