could you tell me what angles you are running on your links and j-bar I am having a terible time getting my car to work on dryslick ......Its a three wheeling rocket on tacky ( a little to much side bite )but if I drive it hard its fast.....I thought if I left the setup the same for the main the dry track would come to my set up ,but the car is no better than a top 5 .....and just cant get a consistant lap on the dry.....anyway it sounds like your car is working good with a similar set up as mine ,I was hoping you could give me some numbers.......I may be gaining to much cross when the car is hiking up....geees I dont know I feel like I am chasing my tail with this thing ...Any help is appreciated.

Lr-16 deg.
Rr-12 deg.
J bar-22 inches at 20 deg. bottom hole on pinion

I have to tell you though that my car is very old, pushing 14 years and doesn't have but 53.5% rear in it. I've also put a 1/2 inch of static roll oversteer in the car.

As far as the car being tight on exit, mine is. Its probably not as bad as yours though, with only 53.5% rear. It's just a little tight. The car hikes up in the center of the corner and I can feel it bite and I start to lose the front end. If I get back in the gas when the car hikes up, it steers the rear and goes around the corner. It felt really weird at first and I backed down when it bit, and it just pushed horribly. I got mad one night and stood on it and it went around the corner like it was on a rail.

If you're overdriving the car on turn entry, then it's not going to be fast on a slick track. You need the car to roll freely into the corner. I always ran the rear end square, but it was too tight on entry this year so I put the 1/2 of oversteer in it, and it really seemed to help the entry. If you can ease into the corner then you can get back into the gas quicker and make the staights longer.

Let me know if you need anything else, and tell me if anything helped.

also, I'm running the Lr spring on a slider in front, with the right rear in a spring bucket on top.

Thanks,I am running 20 degrees in my left arm and I think that may be part of the problem the other part is the car just wont roll into the corner ....it sounds like 1/2 inch trail on the right rear might help....I have been keeping my rear square because I have been told leading or trailing the rear is a crutch ...but I guess if its a crutch that will get me through the turns I am game....is the angle on your J-bar measured from heim to heim ?,If you could take the time would you measure the height differance between both ends.....thanks again ! we have a big 2 day show this weekend Ill let you know how things go.

I can't really get down to where I can measure them properly, but I can tell you that it is in the bottom hole on the pinion mount and 20" from the ground to the center of the heim on the chassis mount.
