Default Tweak

I've gotten a new chassis and it all went together fine. Im adjusting my tweak and as usual, the left side wheels of my car are always the last to come up because of the weight of the engine and muffler.

I adjusted the tweak so both wheels rise equally but now my chassis is tilted lower to the left. I no this will affect cornering and handling in general.

Any solutions? Should a put counter weights of try to lighten the left side or is it a simple shock adjustment? Thanks alot.

How are you checking your tweak? Are you using a tweak station or are you lifting the front or rear at the centerline of the chassis? Sounds like you are using the lift method. It that right?

Before you can check your tweak you need to make sure your shocks are built to the same lengths between the left and right sides. To use the lift method you need to make sure that the droop is set properly first. This means that the maximum down travel of your arms without the shocks installed needs to be the same left to right.

Do it in this order.

1 make sure the shocks are equal lengths
2 install only the front shocks
3 put 4 new tire on the car
4 lift the rear and adjust the down travel of the arms so the tires lift at the same time
5 install the rear shocks and remove the fronts
6 lift the front and adjust down travel just like the rear
7 now install the front shocks and recheck the rear and then the front.

Having more weight on one side of the car won't cause what you are describing.

The easiest way is with a tweak station and follow the instructions below.

If you really want to go crazy, put your car on this:

Well, yes, 339,- Euro's is a bit expensive, so after some internet searching:

If you order 4, it will cost you somewhere near 50,- euro's.....

A friend/fellow racer did order them, and it really works very nice....
It is really incredible to see how a small adjustment on 1 spring, affects the other 3 wheels.....

How do you adjust down travel? My right side comes up first without the shocks mounted.

You should have grub screws that go through your lower arms and hit the chassis when your arms travel downward.
