the car will get really loose in a hurry if you pull the lf and lr. i have pulled both, and also pulled both fronts. when you pull both fronts the car is impossible to drive, and when you pull both lefts the car is imposible to drive. best bet keep it on 3 wheels.
my car can get teh lf about 15 inches before the lr picks up, so maybe you should look at your frame, is been hitting hard, also maybe you should lower the underslung some, make a curve in it so it goes down.

Assuming a 2400 lb car, a 108 inch wheel base, and a 1200 front weight, you pulled 20 G's.

Drove a HASSY car last season that would pull both front wheels when tacky. I think the "g force" figure is wrong, maybe because it doesn't take what the bars do into account. If the rear end was mounted solid it might take that many g's, but a human passes out after about 10 .... shrugs

We had a brand new big name chassis that would lift the left rear in the corners with a 2 link. Of course the reason was the factory mounted the left upper shock and spring mounts too high! We jacked the car up from the frame and we only had 4 inches of travel. Combined with a low roll center it would pick the tire, then head for the wall.

You are correct Dirtmod (i must have been in a diabetic stuper), the correct number is 3 G's. WT = G's * car weight * CG height/Wheel base, so G's = 1200*108/18*2400 = 3. Thats still a lotta G's for a mod, sure it diddn't hit a bump? I'm glad i don't have to race aganst that torque monster.
