Very specific Porsche wheel sizing question

[Acast94]

Alright I have come up with a final set up for the rears.
275/30R19 with a 20mm spacer

in the fronts I want to run 235/35R19 but the biggest spacer I can run is a 10mm
a 10mm spacer will put me flush against the fender for the face of the wheels but I will have an inset of 19mm

In other words these new wheels will stick into the suspension parts 19mm more than stock

Is that too much? Can I get away with this setup and not damage anything

Only way to know that is to get behind the wheel and measure back to the struts.

From my understanding, you can get away with a 17mm inset to the suspension on the front. So 12mm spacers would fix the inner issue. That would leave you with 21.1mm poke to the fender. Also remember that the 235/35/19 tire will be 10mm closer to your wheel opening then your 225/40/18 tires. If you can't get that to work, then you can't use those wheels.

Caveat: 17mm inset to the suspension was with 18" wheels.
