As usual, day one competition on Friday was all about getting familiar with the surface and adjusting launch rpm for best 60 foot and reaction time. I was unable to get some practice launches, so testing the new clutch would happen during competition. Eventually, 4000 rpm clutch dumps proved to offer the best 60 ft. times in the high 2.2 second range. Leaving on the third yellow, my reaction times sucked as usual mostly between 600 - 700.
The courses were very demanding with back to back decreasing radius sweepers heading into the finish. With the extra grip from the concrete and nature of the courses, I raised the rear ride height 1/4" to help get some more rotation. As the surface rubbered in and got faster it all came down to Saturday morning (day two) where yesterday's OPR slowed me down on the first left side run and a very brief rain spat took the edge off my first right side run. My final two runs were quickest, about four tenths per side from the top spot. I did not make the challenge.

I have been using the rear ride height adjustment (rake) with good success to get the car set up for different conditions or surfaces. Although quick and easy, the positive rake adjustment can cause too much lift-off oversteer and the car can be too twitchy transitionally. For my next suspension tuning experiment I plan to stiffen the rear springs by 30-50 lbs. and keep the rear ride height low, or reverse rake. This should give me the best of both worlds; good rotation without sacrificing as much transitional stability. Or that is the idea anyway. The Racing Beat 1.125" front sway bar is already adjusted full stiff and I don't want to try the monster 1.250" bar yet.
