Hey guys, I have done some research, both here and on other sites but I am not coming up with the exact answer I need.

So I do track days with my 2002 SS. In all my previous track days I have used a 255/45/18 on all 4 corners.

I bought a set of 17 inch ss wheels to use just for track days. I am getting ready to get a set of Toyo Proxes r888 (I found a really good deal). I am definitely going with 275/40/17 on the back. My question is, should I go with 255 or 275 on the front?

I know that with the 275 up front, it will feel heavier in the curves and might get a little swimming feeling over bumps/rough spots. With 255 on the front, I have had some under-steer and over-steer. I drive pretty aggressive, but I pretty much have to to keep up with all the millionaires with their Ferrari's and Porsche's.

My car is lowered but from what I have read, I still shouldn't have any clearance problems.

If anyone actually has track experience with a 275 on the front, please share your opinion. Thanks!!

Search the threads on the first couple pages, I know where was a guy running 285 square who posted in his thread recently. Maybe they will see this or maybe not.

Those 255s will be holding you back quite a bit. These cars came stock with 275/40/17s all around, and guys who are serious into auto-x run 11" wide wheels with 315s on all 4 corners, and the front actually has more clearance than the rear. You have absolutely no reason to run narrower than 275s for a car setup for handling.

I track at Road America and run a 275/40/17 & 315/35/17 stagger on Nitto NT05s. A little bit of understeer, but nothing unmanageable. I wouldn't run anything narrower than a 275 on the track if your looking to run hard w/ higher cornering speeds.
