Roll on rr

[CHRISTINE]

Whats the normal amount of roll on rr on a spring behind car?
Im getting 4-1/4 inches on my slider mounted in front of rr is this to much?
200 LB RR SPRING WITH 93-5 OIL SHOCK

sounds like to much but wheres the panhard bar if it has a lot of rake in it that could be the reason also a 93-5 is an easy down shoch might try a straight up 95. how's the car handling lf on the ground or 3 wheelin

[CHRISTINE]

J bar is center pinion 5 inch up on frame 18 degree ru bar 1.0 rl bar it is carrying lf about 12 inches through center and off

could go to a 225 rr and put a 25lbs lead weight as far forward inside the left door and up about half way in height.The 25 lbs would be about where your feet are at .

[CHRISTINE]

I think im gona try the 225 first what is a good amount of roll?

[hammond]

3-3 1/2'' but all depends on where your spring is mounted at . If the car still picks up the Lf more then 1-2'' then try that weight

[CHRISTINE]

Ok.
My lower mounting point is 12 inches from inside of tire with 2" off on the rr and the spring lays in 15* and forward 9* is that to far away from tire?

[hammond]

Thats about 3" inboard more then what I run . That will work just need more spring and maybe a little stiffer shock . I would not move the coil over just work on the spring rate at this time .

[CHRISTINE]

Thanks im not on a coilover on the rr i have spring in front and shock behind all on b/c does that matter

If your running spring in front the shock should also be in the front.
