I can't confirm that it will work as long as your fenders are rolled. The maximum width for wheels in STR is 9" and the max tire width is 255. So obviously that what most of the autocross guys are running.

I haven't done anything with mine yet so I can't confirm that rolling is all that is it needed or if it'll fit if you're lowered or what camber adjustments need to be made.

My front fenders are rolled with a slight pull. My rear fenders are rolled, bumper trimmed, and rear bolts relocated. I fit 255/35/18 tires on rota d2's. I believe the offset is 48 or 50. I too want to switch to squared rpf1's for the track but am worried ab out the 255 fitting up front. I don't mind pulling the fenders to the max if needed. I also have some 1.6 degrees up front, and 2.5 in the rear. Can u guys help me out? that pic with the guy running the 17x9 +45 on 245's looks like he's barely clearing and would rub at the track?

Non RPF1 info...sorry...

If you're looking for an STR compatible auto-x setup and 17x9 wheels, you'll want more offset than 45mm. The 949Racing wheels were made for this application and the 63mm offset works very well. With a minor drop (~5/8") and -1.8 degrees of front camber, my 255/40/17 RS-3s barely rub the liner in the front. I have not rolled my fender lips at all. A 45mm offset is going to require you to change the outer contour of the fender, which is not class legal. If you don't pull it slightly, a 255 will do it for you. The 63mm offset, on the other hand, will only require slight rolling to avoid rubbing.

In the rear, 63mm offset and 255 doesn't rub at all.

Yeah, this is my problem... I could probably score a set of used RPF1s for cheaper only because they've been out longer and non racers really like them even though they don't care about weight.

The RPF1s also like a pound lighter unnofficially (meaning I don't trust the internet "scales")

Some used 6URLs would be perfect also, but I doubt anyone is getting rid of them yet with STR growing so quickly.

EDIT: I'm just poor...

Just ordered Black Enkie RPF1's 17x9+45 from America's Tire Company today. They do price match so I got mine for under 1k. I just wanted a good reliable set that's new. I get my 255 RS-3's by fri and I will try to post some pics by the weekend.

Sweet!! Let us know if they rub and if you rolled the fenders, also if you are lowered.
