Well we took our FD to the track a couple nights back for some shake down runs. We had a set of Hoosier Quick Time Pro's 26x9.5x16 slicks and the air psi starting at 12.5. The car left with an easy 1.59 60ft but when I went to second gear the car took a hard right turn towards the wall. I get it back straight but every time the car started to make power it was all over the track. It has a Kaaz dif and we were running space savers up front.



My question is what toe-in and camber setup should I run on this thing. I am still very new to RX7's and their chassis.



Here is a link to the video of that run. http://www.sks.lv/video/rx7.rm

My guess is suspension bushings need replacing?

They have been replaced. It has to be in the camber and toe of the car. With the street tires on the car goes straight down the track. It ran a 11.8@132mph with a 2.2 60ft with 275x40x17 V700's out back.



I am pretty sure that if we can get the car to go straight down the track it should run some mid 10's.

have you made any rear suspension Mods? if its running right with the street tires but crappy with the others the suspension geometry it correct, I would check the operation of the diffand tire pressure settings. I came to that conclusion because it only happens under power. If one side squats then the pressure on the footprint changes which in turn changes the overall circumference of the tire making it pull to the side.



Hope it helps.
