wedge adjustment
the previous post is 100 percent correct on how to adjust wedge,EQUAL turns in and out on opposite corners.it does not matter at all what the spring rates are in the front and rear as long as you adjust them equally all you are doing is shifting the weight on the springs that is why the ride height will not change.this is why a bubble level tweak gauge doesnt work properly ,it will help but it doesnt take into account that weight shifts diagonally in the car also.as for the post saying the integy unit isnt reading properly i often find weights close to his in other peoples cars(tc3 especially)after setting wedge properly they cant believe the difference it their car.the other huge benefit if the weights are the same and nothing else was changed you know the car will be exactly the same as the last time you used the setup.this is how all real race cars are setup consistantly.
