That is a great price on a set of Q3's. I really like those tires for stickability, but the rear only gave me approx. 2700 miles, so don't expect them to last too long unless you are really easy on the throttle and don't run too many twisties.
Just put on my 3rd set of Q3's. Yeah they don't last long but the grip makes it all worth it!
I was running some twisties in A mode this weekend and would launch out of the tight corners in 2nd gear. Kept waiting for the rear end to break loose but it never did! Feels awesome to have full confidence in your tires (when warm). Now for the dreaded suspension..
