One of the suggested performance improvements for the next race is to significantly soften the suspension. I have recently learned that both the spring rates and the tire pressures I have been running are significantly greater than the competition. So out came the spring collection, and I softened the fron and rear rates by approximately 150# each. Hope it works...
The funny thing is that after changing springs I went to the trouble of unpacking and setting up the alignment platform. I was particularly concerned that because I had to go from 4" to 5" springs at front, and 5" to 4" at the rear to get the rates I wanted and therefor had to move the spring perches and reset the preload that they would be significantly off the original setup.
Looks like I needant have bothered. The corners were within a couple of pounds. But you never know until you check. This DOES bode well for any last minute at track adjustments though. I can be confident that I will not completely screw up the setup by changing spring - as long as I am fairly methodical in setting preload.
After a minor adjustment (1/8 turn or so)... Right on the money...
** Note this is the car weight without nose, engine cover or (most significantly) a driver.
So on goes the body work and in goes the driver (minus helmet)...
1106# more or less ready to race. Right about where I want to be with a little fuel in the car, and all fluids topped off.
