I had the BF Goodrich G-Force Sport tires installed on my car last weekend. They were put on the rear only and are size 255/50/ZR16. Also a softer compound than the last tires.

I tried them out today for traction. They still break loose in 1st and 2nd gear. The motor is still over powering the tires. Hope the Mickey Thompsons ET Street Radials grip at the track.
