stiffen up lf spring

Make sure the dampner shock isn't bottom out or maybe the drive shaft bottom is tranny. Just some ideas to look for, are you running a brake biscuit on pull bar.

If you are on a 4 bar right side, drop lower bar, and raise top bar.

Have not tryed stiffer lf. Have 100lb.split.Maybe go to 50lb. split. Top shock not bottom out. Driveshaft pulls out when off gas,right? Yes brake biscuit. Bar angles doesn's seam to help. THANKS for reply.

our driver likes a tight car on entry but not mack truck tight and we have a 700lf 650-550rf spring on a chevelle front clip 4 bar car.

if your car is tailing out after you decel because the car drops so hard you might need to stiffen up the left rear shock compression and gas pressure (if its a monotube) and learn to trailbrake (brake before you let off the gas).

Yes, I have 7-2 or 9-2 left rear shock,but aftercar settles,it feels like rear tires come unhooked and it want to tail out. 650lf 750rf 150 lr 225rr .

Do you have a liftbar with a chain to control pinion movement?
If so. Take it off. when you let up on throttle and the pinion moves down, it hits the chain, and takes weight off the rear wheels, causing a loose condition. Jsut another thought.

I would swap front springs. that will tighten entry for sure, or put an 800on the LF , and leave the 750 on the RF.

..Bar angles doesn's seam to help. THANKS for reply...

There is something other than springs. How are you/driver entering the turns? Are you throwing the car in or driving? The car may be to tight already and the driver is compensating with his driving style.

Bar angles should make a difference even if it is a one hole change.

Why such a soft LR spring and stiff front springs?

Afraid swap springs, to soft rf. Change bar angles seems to hurt forward bite. Start with 150lr 175rr change 225rr helped going in & shock travel o.k.on rr. May try stiffen lf. THANKS .

Loose in o.k. adjusted wedge & lowered rrlower bar. tight in middle car doesn't roll through corner. ar. rear temp after feature lr 160 rr200.

You could raise the rrt bar for the middle problem. Do you have any lead/trail in the rear end?

05-25-2010, 12:00 PM
Yes about 3/8in. Thanks for reply. thats lead.

05-25-2010, 12:53 PM
If its rr lead, try running it even, that should help the middle problem but it might be too loose in. Good luck.
