Your car is awesome! Love the set up and hopefully I will see you at one of the SoCal track events. I've always wanted to do CalSpeedway and it looks like a really fun course. I'm going to Big Willow this Saturday (1-12) with SpeedVentures. I'm a newb and just beginning tracking.

By the way regarding your speed...I was just looking at my P-box data from my latest track event and couldn't believe how optimistic the stock speedometer is at that speed. On the back straight of Big Willow at the Dec 29 Shift-S3ctor event, temps were very cool and my speed-o needle was passing 160 just before the braking point on the back straight after turn 9. But my looking at my P-Box data I was only going 145. Comparatively, the speed-o is off only a few mph at 80 mph...but almost 15 mph at 160. Very strange. I'm running larger rear tires as well (275 Mich PSS).
