Good info. Have you done any suspension mods yet or are you still running a stock setup?I just raced with Bridgestone BT-003RS street/track tires and they are great! They come in the correct size too.
Here's what I mean by great... great grip, great wear. The track I raced at (Nelson Ledges) is a 2-mile track with 13 turns. My lap times were 1:29s, which translates to an average speed of 81mph. Those Bridgestones stuck to the asphalt like glue.
I might check out a set of Continental Road Attack 2's using the 150/70 on the rear.
