and .04 deggrees of camber on the driver side wheel
. I'm thinking of trying an offset shaft on the right upper control arm to band aid the problem.)
Anyways I went to the new years race with the new 350# springs and tuned the front shocks with 2 of 24 clicks from soft on the extention and 16 of 24 clicks on the compression and the car left with a 1.39 60 foot and ran 6.36 in the eighth mile and felt really controlable for once except for the slight pull to the left I think is caused by the camber thing. We ran eighth mile because the track was very wet from rain and about 55 degrees cold. I think thats an improvment
ITUSO. Any time you have over 1500+ lbs on the front, we use the 350lb springs.
Have you had the car on a good front end alignment machine? If not, you should, another thing is rear spring rate. Both have to be the same. If you run the right rear spring up tighter thinking you are doing something, this will help in the launch, but when you hit the brakes, your car will pull to the left. Very dangerous and people do this all the time. We just preload the chassis to make the car leave straight and leave the springs alone. Good run, now just make little changes from hear and keep the basic tune up for back ups.
