I have a metric car and it seems to be rolling over too much causing the rear end right tube to hit the frame. Car has a 3 link and I'm thinking that maybe I need to change the angle of the panhard bar. It is 3 degrees down angle to the left now( left side mounted) and fairly low on the mount. I was going to try moving it up one hole on the left and down one hole on the right to get a 3 degree up to the left. Should I be looking some where else for the fix? Here is the set up on the car. 1/5 mile paperclip dirt track that is pretty rought in 3 and 4( pot holes) where most of the problem happens. Friend told me car is rolling over more than the other cars.
53% cross
54% left
52.25% rear
total weigth 3432 with me (190)
lf 832 rf 804
lr 1020 rr 776
no sway bar
springs
970lb lf 1150 rf
250lb lr 195 rr
Also rr shock started leeking sometime after the heat race and its a pro 95, maybe needs to be a 96?

I would say that your rearend is walking underneath the car during braking and upsetting things. Causing the shock to bust and binding things up until you settle the thing under acceleration. I'd try to slow down the shock travel on the rebound of that left rear. Are you running out of travel on left rear like its trying to pick it up? I'd definitely try lower the thing down some in the rear ride height wise.

How much travel do you have before it bottoms? I am thinking maybe it bottoms first then the left rear has to lift? And are you sure the left rear shock isn't extending to easily? Also seems soft for the right rear spring given your conditions. Just some thoughts, been wrong before though, lol.

I'm thinking the cars a little heavy, with a lot of rear weight for those springs & track and no sway bar. For grins (and no $$$) try the 250 spring in the right and 195 in the left for warmups. The springs are what determines how far the car will roll, the shocks just change how quickly it moves. So going with a harder shock might slow it down some, but it will still move just as far.

I had though maybe to light on springs but I am not sure. I bought all four springs used untill I figure what I need. I would moving think panhard bar would help some. There is about 3 inches of travel on the rigth side tell the axle hits frame.I dont think lowering ride height any more would help. It only botoms out on rr when you hit a large bump on the corner. Raz900 do you think all spring are to soft. Also those scale numbers are from toll box scales(scale are very cheep so dont know how total weight is) Also left rear shock extends just tell spring is about to fall out and right is not bottoming out or binding up. Rear suspension moves very freely. I will try reversing rear spring. Been thinking about trying that every time I read on here where some one else has tried it.
