Suggestions on tire fitting....

I have a 2000 WS6 that I had bought a rear rim size of 17x11 with 17x35x315 tires to fit on the back end and never had a problem stock. I have recently dropped the the car with Koni street shocks and Eibach Pro-Kit springs which brought the car down roughly 1.5 to 2 inches. Now I have the inside of the wheel well with an edge that is cutting into the tires and I'm rubbing if I hit a bump. I went to a shop and they ground the lip (which was sharp like a razor blade) down as far as they could go without there being a split where the metal comes together (his words not mine). But I am still having the hitting issue when I hit bumps, just not shredding the tire wall like it used to.

Any ideas on what to do without having to do major body work to the fenders to widen them or shorten the rear end? Would putting 305's instead of the 315's on there make a difference? Also I wanted to put Nitto's on the back and have heard they are a smaller fit (any truth to that or would that help).

Just trying to find a cheaper route for now after putting over 10K into the engine and other work done. Thanks in advance.

first off, no such thing as a 310mm tire width, the next size down would be a 305. what you need to do is what is called the BFH (big f*ckn hammer) mod around these parts, do a search and you will find a bunch of threads of people doing it. i had to do it to fit 295/35's on an 18x10.5 wheel so I'm not sure you will have much luck unless you go down smaller than a 295 (which would be stretching the tire quite a bit).

Yeah BFH, and also make sure your rear end is perfectly centered, on the chassis / inside side, not the fenders so much. I had major rub on my inside left tire but not the right one, I know exactly the spot you mean that cuts into the tire. Also if you have stock rear LCA they have an upturned lip that can catch really wide tires on hard cornering. So I adjusted the centering, its not so bad now. I have a watts link so centering is easier... you'd need an adjustable panhard I think to center it if you don't have watts. Without a watts you might get rub when cornering b/c the body moves asymmetrically with a panhard.
