Running a 3 link with spring on top rr on a dry slick track. Have a J bar in it now, thinking about changing to a short straight bar. Would this be a better setup for dry slick?

Works much better. I use the 19" straight bar to bottom of pinion to left on frame mounted to begin with about 3-4 inches above left underslung.

Have you tried putting the RR spring behind? It really helped with side bite on my car. Everytime I put the short bar on my car it gets a radical push right in the center and if the track is rough it's tough to tame down. I've tried short bar lengths from 12-19" and the results have been the same.

psycho47, I haven't tried the spring behind yet. But I was thinking about it. Just wasn't sure how it would affect exit. In other words, wouldn't it tighten it on entry but want to loosen when you pick up the throttle?

I am no expert, I just try something and see how it reacts but it tightened my car all the way around. I believe that with axle rotation it unloads the right rear under acceleration and you end up with a lot of left rear drive. I changed the bar angles to get more roll steer through the center of the corner to get it to turn better. I am going to try a tie down on the right rear this weekend to try to keep the car rolled over a little longer to keep the roll steer through the apex. I will probably put the rr spring on top for tacky tracks because of how much tighter it made the car and switch to the coil-over behind on dry.

RR behind should actually tighten all the way around. When you get back in the throttle, the RR spring will decompress. It helped tighten my 3link a ton.

oops, posted the same time as psycho. Definitely have the right idea. We run a 50/30 shock on the RR and 30/50 on the LR for the dry.

What type of panhard bar are you using ? Shorty or j bar with spring behind?

j-bar, 19" long

second to bottom hole on pinion, w/ almost 7" of rake. When tacky, less rake helps free up the car. For some reason, my jbar runs REALLY close to the driveshaft if I run it in the bottom hole on the pinion. Otherwise, I'd run the bottom hole with less rake.

if rules allowed, I'd have the short bar on though. Hooks up a lot better on a smooth dryslick track than the J-BAR. If your running a rough track, I'd stick with the J-BAR.

Thanks for the help. I'll try something this weekend and let you know how it worked.
