What tires are you running? I can tell you now they suck. If you are running 2.1 60' then you need better tires. Get you some of the widest tires you can for the back ones. Also launch higher. Launch at 3,000rpms and slip the clutch alot. Will get you in the 2.0 or better 60' then after that shift where you should and you will get the time that you should. Also racing at this time of the year isn't going to be nice to you at all. The ground is cold and your hopes for traction are pointless. Wait until next year. When the ground is 70 degrees and up and you are still running slower than you should THEN you should get worried. But running 2.1 60' in 50 degree weather is usual. (all this applies unless you are running DRs or slicks)
