[Pyrat 2]

I am currently running 235/40-18 MPSS on 8.5-18-45 Forgestar CF5. No rubbing - zero. Very cozy fit though on the strut side to be sure. I have BMWP springs which lower the car by about 0.5 inches. I also have Dinan camber plates which raise the car by about 0.25. So net lower is about 0.25. Negative 1.5 camber is dialed in. I'd feel confident that with your setup you can make it work.

I have 245/35 on the back with the same wheels. I tried them on the front for fun and they will need a 3 mm spacer to work with no rub on the strut side.

Hope this helps.
