that car can achieve much better times, you just need to do something to keep from burning your tires/bogging. 2.2 60' is not the best an auto 3.91 330i can pull, you should be able to shave over 1/4 sec from your time by launching the car without tirespin. are cup kit shocks adjustable?... set the fronts soft, the rear stiff, this will help slightly, take some air out of your rear tires. Actually do a burnout before launching, this is a technique that I've had good results with. I know gyear f1s aint cheap, but you need to get some heat in them tires before you launch.
