Running the 325/30/19 Porsche spec Cup 2's on rear R rims

Who do yall have install tires on these wheels ?? I think i'd lose it if someone damaged them.

Locally I use these guys (they should be national). They have the right Hunter machine and they do an awesome job at my house. https://on-sitetires.com

If you don’t track, stick w ps4s. If you do use mostly for track, give a supercar 3R tire a try. Its one developed for zl1 1le, and just as fast as cup2s at much lower cost. They both seem to last about the same as well..

Here in SoCal the 3R has been proven to be almost/about as fast and lasting a similar amount on track as the bespoke GT350R PSC2 but with worse steering feel and needing more camber. That's on R-width wheels.

They are cheaper but have downsides and are not a slam dunk. FWIW, Nitto NT01s are in a similar boat.

I'd recommend 295/305 PS4S on R-width wheels over 305/325 PSC2s for street driving.

Thanks Billy, though I will be tracking the car once I get the roll bar and a tow hook installed. Even though I drive mostly on the street, since I will be tracking the car I was going to try the N spec Cup 2's in the hopes that I may get more than just a couple weekends out of them. I'd prefer not to drop down in performance to the PS4 levels.
