first thing you have to do is set your tweak, then adjust your diff until you can hold both rear tires until your barely able to turn the spur gear. my 3.2r was near perfect, out of the box, use the stock settings and you should be in the ballpark. if the car still unloads, then try using less tracktion wash on the front. use about 1/2 the tire with. if it sill does it try different springs on the shock.

hope that helps
