This isn't so much for track setups but a good conversation for us to have since this car is new and many of us will be adding different wheels and tires:
Another 600lt owner (see PUR wheels website) has PSC2's on 235/35/19 and 305/30/20 and the fronts RUB on the front plastic duct liner (specific to the 600lt). Not bad but enough to see and hear it. No offset helped this either, so I don't think we can get a 245 to fit and not rub on this car....?
I'm curious why Finspeed for example doesn't do a wider rear either? OEM is 11" wide with a 285, so going to a 325 really would necessitate a wider rim. I would assume the car can fit another .5-1.0" wider in the back?
I have a set of PUR forged wheels I'm considering in 19x8.5 and 20x11 with PSC2 235/35 and 305/30, per the customer above, but I'm still trying to decipher what the best size/setup is... and I think adding .5" to the rear is a good option. When you examine the section width below, you'll see what I mean.
Front Trofeo 225/35/19 9.1"
Front PSC2 235/35/19 9.5"
Rear Trofeo 285/35/20 11.4"
Rear PSC2 305/30/20 12.3"
The OEM Trofeo's fit pretty well on the OEM wheels. The front tires are pretty flush with the wheel lip. The rear has a little more rubber on it. So, adding a larger tire to the rear +20mm probably should necessitate a wider rim. Same for the front. Using a 235 should take a 8.5" width wheel. However, both PUR and Finspeed are still using 11's in the rear.
The other problem is some molds (one manufacturer to anther) are different in tread and/or section width so a PSC2 could be larger or smaller than say a Trofeo in the same exact size. I really wanted a 245/305 setup on the car so the front and rear are a +20mm but I think that 245 up front will work?
