I love those same tires on the street on my car.

I can tell at the limit that they are not as grippy as the OEM Trofeo RS, but that is kind of a "duh" observation, and I should not be at the limit on public streets, anyway. I have been happy with their performance.

Tire damage from rubbing

Ahhh I think I now know why you are rubbing. You are still on 35 series rubber vs 30 series rubber. ChatGPT says the overall diameter on your 295/35 is an additional .8” - so if it’s just BARELY rubbing for you I should be fine.

I added the wheels / tires but went down to 305/30 and 315/30 and I have a SHIT ton of room lol.

even after I add the 1” drop I’ll still have so much room with the 30 series tires that I don’t believe we will rub.

look at the wheel gap

Your tires wont rub, but you'll be dragging the nose and underside of your car on curbs, speedbumps, and driveways. Trust me, I know from experience. My front splash shield was almost completely destroyed after a year.

That was the reason I went to 35 profile tires. Taking the fender lips off eliminated any tire rub. 285s up front will get the tires flush with the fender.

Yeah maybe so- not that worried about it too much tho because it’s not a daily driver. I’ve only put 6000 miles on it in a year. I’m also extremely careful about how / where I drive. Hopefully I don’t have to replace these bits every year lol
