Guys I need your help again, Car is pushing BADLY, it put me into the wall lastnight. I have not been able to get it scaled yet. 3300 lbs, 3/8 mile, med to steep banking, clay track, long straights tight turns.

lf950 afco
rf1200 afco
lr225 flex-a-form composite
rr200 flex-a-form composite

2" lowering block in LR
stock mount adjustable pro shocks
stock offset wheels, 12 bolt rear thats not been changed over to 5 hole. I did just purchase a 2",3",4" offsets for the front.
Tire pressures range from 12-14lbs on the right side, and 8-12 on the left side
We can't use weight jacks, I do have adjustable spacers, that are set the same.
Thanks ahead of time.

Scoot, check your front springs(make sure they're in the pockets), your front shocks(working properly?), and get that thing scaled!! Lots of things can cause a bad push, but the first thing you should do is scale. Jeff.

If the car just started pushing this week and was fine previously, I would look for bent or damaged front end suspention and steering parts also check caster and camber for proper settings. Also check for chassis binds. If your brake bias is adjusted with to much front brake it will cause a push. also try more rear stagger, If after you have tryed these and still have bad push you need to take some cross weight out or try a lighter RF spring. Just my 2 cents.

millerlt3, It has had alittle push in the past, nothing as bad as this time. I dont use the right brake on the front. If the left front brake is locking up would it cause my problem?

Scoot, ya I guess It could If you get on the brakes hard going in and It lockes up starting the push condition the car never has a chance to roll over and start to come around. Try driving it in differently or set the car in the corner with the throttle. Did you check out your front end? Also you said you put a 2" block just on the LR can I ask you why. Because if you always have the LR planted youll never get it to turn. I dont know if the LF locking up Is the biggest part of your problem. Also put as much rear stagger In that you can and see if that helps. Let me know.

Millerlt, The reason for the 2" block is it was there when I bought the car. If I take it out wouldnt it tighten me up? I got as much stagger as I could in the rear. I put a larger left front on and kinda played with my air pressures and the car handled great. Until my brakes went out. Then I had to let off earlier than I would have liked to. When I worked on the car this week after I crashed into the wall. I noticed the shocks were binding with my spring spacers, so I changed back to my old springs and some stock shocks.

Hey Scoot,
My car sucked last night...or should I say it was me...I'll say me. It was way wetter then what im used to driving on so that was the part that I sucked on because I couldnt keep up with my steering...but coming outta the turns my car kept wanting to spin out in the feature. It started aggrivating me because I didnt want to spin out in front of anyone so i just started to drive it around like you would dryslick. My dad kinda got on to me for not throwing it in but i didnt feel comfortable throwing it in when it was that loose off. It started to dry up a bit and we had i think 3 1/2 inches of rear stagger which i think was too much. I hope it dont rain later this week where it'll be dryslick.

Scoot, No, When you put lowering blocks on a leaf spring car it lowers the rear roll center, so you will get more side bite which could cause a push. So if you take the block out it will raise the rear roll center which will take away side bite and loosen the car up. If it were me and I couldnt get rid of the push no matter what I did I'd take the block out and give it a run. I think it will help loosen you up a bit. Let me know if it helps you.

Millerlt, I'm going to leave it the way it is now. It handled too good friday night to change anything right now.

Millerlt, The best I can tell, the spring spacers and shocks were binding up, not letting the suspension move like it should. I put my old springs and some new stock shocks in it. I also put a larger left front tire on it. I put caster in the left front and set the toe alittle different, I just eye balled it. I also had some brake problems, I've replaced both front calipers. I still need to scale it but if it will handle this good I may not worry about it for awhile.

Scoot thanks for the reply, and hope you have good luck with your car. There is nothing as ILL as a car that constantly pushes.

MIller...It depends on where the lowering block is mounted as to whether it will add or subtact bite from a car. A 2 inch lowering block under the axle tube lowers that side of the car and takes bite out of the car, assuming no lowering block in the rr. THe opposite would be true if you removed the lowering block, it raises that corner of the car, therefore adding weight to the lr tire and adding bite, tightening up the car. Let me know if you disagree, or if I misunderstood your post. Dont get me wrong, not trying to start anything, just clarify this, because leafs kinda work backwards from coils.

Scoot, for your shock/spacer bind you can relocate the bottom mounting holes on your shocks to alleviate this problem. Most of the time you can twist the shock until it is clear and then just drill one new hole.
