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
As long as you have some that is over center, you should be fine. The slight pull, is that on the hit also? If it goes straight on the hit then starts to pull a little to the left, that is most likely alignment, if it goes to the left on the hit and you have to steer it back to the right, you have to much preload on the right rear tire! Take a of a flat off the adjustment and that should bring you right in. Either way, both shocks extend on the hit and both shocks compress as it goes down the track for the front and rear. The rate of the extension and compression is where tuning comes in. you can slow the rate of extension on the front down and it will carry more weight from left front to right rear and vice versa. Same with the rear. Slow the extension rate down on the left rear and the car will go to the left easier because the rate of extension on the right rear will allow more bite to the right tire. With the front your just playing with weight applied to either left or right rear tire from the transfer, which will also cure some chassis handling issues.
