Sport Mod rear suspension

Never been a big fan of dropping panhard bar to add side bite. We didn't ever change ours last year and our car was fast in the slick. I believe that other things are much better for helping the car get over (go to a tie down on RR, soften RF spring, soften RR spring, lower right side bar on the chassis).

Extending the LR bracket would be a great benefit, so u can get the bar angle up to atleast 20*. When the track slicks up u wanna add more side bite to the car and more LR drive. Side bite (move panhard bar down on rearend) which will put more angle in the bar which plants the RR in the track harder, lowering the bar at the rearend lowers the rear roll center which helps transfer more weight to the rr which also plants the tire more. Adding more bite gives the LR more weight which drives the LR tire more, More angle in the LR bar will give the LR more drive (forward bite) Springs, bite and shocks pm me. I live in the area if u need anything[D

Doesn't lowering the rear roll center give you more body roll but less weight transfer to the rr

Isn't body roll chassis roll? Chassis rolls over on the rr spring harder. In my experience raising the panhard on the chassis puts more side bite in the car but tightens the car from the center off. By lowering it on the rearend it seems to give u more side bite from entry to the center and keeps center through exit the same

I think what dirtrunner35 is trying to say when you lower the pan-hard bar the car will roll more but the weight will stay on the lr tightening the car not the right rear . Just like when you soften the rr spring the car will roll more but tighten the car off the corner loading the lr when you raise the pan-hard bar that will loosen the car because it loads the right rear more just like stiffening the right rear spring.Just because the car rolls more does not mean you loading the right rear. Is this right I have no ideal I have heard it both ways I am not claiming I know this of anyway.anissa5

The panhard bar only affects entry to the middle. So with more angle in bar it makes the car tighter on entry to the middle cause it's digging the rr into the track harder. With less angle in the bar it makes entry to the middle looser cause it's not digging the rr in the track as hard. My theory with lowering the panhard bar at the rearend is that the roll center is lower so the car rolls the weight over to the rr more causing the car to drive the rr harder than it was with the roll center higher. Yes a softer spring makes less drive because the weight of the car on the rr is compressing the spring more instead of pushing the weight down on the tire. A stiffer spring does not have as much of a compressed rate as a softer spring which makes it push more weight to the tire.

You are correct
