i run the 10's on both sides of mine my driver claims the car was way easier to drive then when i ran the short rf. My car is currently setup with a 7 3/4 mounted to the slider running a 19" lower seems to work pretty good also but driver complains car is darty at high speed tracks like WVMS and PPMS -
That is the same thing my driver says, do you think the car is faster now? I think were slower with the short rf upper, thats why iam trying to find out the change to roll center and handleing.Comment

We changed from a 10" outside with the 17 5/8" lower to the 7 3/4" upper and 19" lower...The car seems to turn in better, but he said it does seem a little more darty....Comment

I tried the long arm on the right also but am back to 7 3/4 with a 19 1/4 lower plus I am running more negative camber than specs. Car seems to turn better on dry slick for me. I have the uppers on Lazer type sliders and set the roll center at 3" off the ground. One thing that I really think makes a difference is to keep the front ride height at specs with driver in and recheck at least once a night between heats.Comment
