Clearance?

I'm not sure about 9.5's up front...I run 9's on the front and they rub evvvverrrr so slightly at full lock, but not otherwise. The 315's on my 10.5's out back don't rub. I'm running a small spacer, and my tips are slightly adjusted accordingly but no rubbing at all. I'm also running pro-kit springs so it's also not as low as yours may be. I also run Nitto Drag Radials which run slightly narrower than some other brands.

i also run 17x9, 17x10.5... the fronts are 275 and rear 315. I used to have an issue with rubbing at full lock in the front but that was fixed when I installed 03 cobra arms. In the rear I removed the quad shocks and massaged the inner fender well.

I would advise against going more than 9 inches in the front. 275's are MORE than enough tire to be holding your front end to the pavement, and going any wider will most certainly cause you rubbing issues, especially at full lock.

Most guys on here run 245 to 275's up front, and 315's out back. Nitto's Extreme Drags run narrower than BFG's and Mickey Thompson's DR's so that's possibly why some have experienced no issues with rub out back. If you do intend on going with one of the latter 2, expect to do some small adjustments with quad shocks and inner fender "negotiation" A hammer is a wonderful negotiator, as Chythar pointed out

I'll add that the narrower Nittos appear in the 17" wheel size it seems. It seems like recently i've read a lot about that not holding true in sizes other than 17s. Now i do realize the wheels in question in this thread are 17s....so....im just throwing it out there.

I run ARE torq thrust II's for street rims with 17x9.5 in front and 17x11 in rear. I had some 275x40 yokohama tires in front and they did stick out ever so slightly past the fender (maybe a 1/8in) and 315x35 in rear. I just had to flip the quads and slightly roll a corner of the inner lower rear fender. On the front it would rub at full lock.

When I installed the 03 cobra A-arms this summer the rub stopped. I did just get some 265x40 mich pilot tires for the front (not on yet still have the pro-stars on). I hope to remove the 1/8 part that was sticking out slightly.

I actually have more of a rubbing issue with my 15x8 weld pro-stars. My drivers side drag radial is SHOT from getting cut up by the fender lip on the outer edge. I plan on rolling the edge up/in a little to not tear up any further/more and get some new MT DR or streets.

How tall are your rear tires?

I measured them and they are around 26in tall they are 235/60. It may also be that I have bullitt springs/shocks in the rear with no iso's and no bump stop on the rear from when I removed the dog bone weight on the diff. I may be getting a tad more flex/movement in the rear. I am thinking of getting an air bag for the drivers side as the passenger side is a non-issue.

If it's on launch that it happens, I would look into an airbag.

Otherwise, if it's on uneven surfaces or turning up hills, the best you could do is roll the lip.

My driver's side does the same thing when turning up hills, and so I'll be rolling the lip once the car is on the go again.

I'm very surprised that my 315 Nitto's don't stick out much further than my 275 F1's did, but i'll be taking precautions this time around.

On launch however, my F1's broke traction before it would make contact with the lip.
