I think we have missed a couple of important questions.....how hard does it pull to the left?? Does it drift over or pull quite hard to the left? And does it do it during off power or mild acceleration??

VONEREFLEXR

It does it at hard accelleration and it is a hard pull, I am unable to correct by steering. when i do try to correct it oversteers and slides.

hurhur

it could be your tires are warpped.
check them especially the fronts.

I think its hard to tell where the problem lies...i guess the best solution now for you is to check your chassis step by step and try driving it after you have done so...then you can move on to other area to find the problem if it is not corrected...

here's a link which will guide you throughout the process...follow the link to 'Basic Tuning Principles' -> 'Chassis Check 1-20 steps'

hope this helps...do keep us posted of the outcome...

seems like you must have something blinding on your suspension system.

Just upgraded a pair of Adjustable Fr Anti Roll Bar and mount from K-Factory Racing.

Juz wondering if i should set the 2 bars horizontally or Vertically at 45 degree? The impulse's fr anti roll bar is set at 45 degree vertically...
thnks

Since it is a new car. Fully compress your chassis til it touches the ground...with the car it this state make sure you have some free play (longitudinal) in your dogbones, if you don't then loosen the pivot balls out a bit until you do. Like Manticore says, it does sound like a slight bind somewhere and under hard acceleration could be one of your rear dogbones.....just a guess!

The angle is to adjust the hardest of the roll bar. Horizontal is the softest setting, vertical is that hardest setting. You should have both equal.

One more thing, to set the roll bar correctly. Disconnect your shocks, lift up one side of the suspension and watch when the other wheel starts to move. Repeat for the other side. The point at which the "other" wheel lifts should be the same, adjust your cam lever until you get this! Takes a little bit of practice!

One more thing. I have found that doing this setup with the roll bar at the hardest setting makes things a bit easier!! Although it is possible to do at any roll bar setting.......

so suspension would have that dramatic effect on the car by pulling in accelleration, I always thought that the differential would have more effect than suspension set up.

they both have a dramatic affect on the car going straight or pulling to the side, now if you gentlemen excuse me i got to put a new pipe on my super nitro

another cause could be uneven toe in, castor and chamber, check to see if the two wheels in the front have the same chamber, castor and toe in/out, do the same to the rear aswell
hope this help

VONEREFLEXR

what degree of toe-out/toe-in should I have as a standard setting

asd

pictures anyone?

asd

you could start with this:

Rear
toe in 2 to 2.5'
Camber 2' to 4'

front
toe out: 1 to 1.5'
camber 2'

anywhere between these degrees is great, just make sure that on the front both wheels have identical set ups as well as the rear tires
