Hey guys, I need some help on getting my car setup. I am running a 4 link mod. My problems is car iss turning in good but from middle out it pushes strait to the wall. I am running a 1/2 mile semi banked and usually slicks off. Shocks are integra avenger base package. Springs are 600 LF 650 RF 175 on LR&RR. 20lbs Wedge. Caster RF 3 1/3+ LF 1 1/2+, Camber 3 1/2+ & 3 1/2-. My car doesnt seem to be rolling over on right front like the other cars are. What adjustments can I make to the car and also driver to fix this problem. Note: i am an inexperienced driver also. thanks for the help

How much rear steer do you have? Too much will cause this.You may also put more caster in the rt front.

Not sure on how much rear stear or how to measure it but the 4 link bars are all to the lengh the chassis reccomends. would moving the spring to the front of the axle housing on the left rear make a difference?

Is your car on the "Clamp" or on the "Hook"

Too many variables to answer that with any kind of conviction. It should be where ever it works the best but where that is depends on chassis overall design and suspension, type of track and driver preference.
Does it get better if you wait on the throttle longer after the car rotates the amount you want?

yes it has to be completely rotated before i can get back on the gas. Even coming o on the initial take off between3 and 4 it pushes up to the wall. I have zero body roll in the turns. front end stays level. I am running the reccomended springs from chassis builder. This is why i was wandering if the roll center should be moved further to the left? thanks

you could try swapping the front springs. you could try raising the LR Lower bar a hole or 2. you could lengthen the right side bars, trail 1/2" or so

What are you running for shocks and what corners? Do you have an all steel motor? Could put weight up high above the heads. Sounds like you need weight to transfer to the right front. Could be pan hard bar height? Help us out. What frame are you running?

Shaw have well designed front end designs. Could be correct and more about camber curve and bump steer. If thats where they designed it leave it alone. Check your messages.
