vodo321- clarification point: I actually meant that if you use the Associated front springs the plastic front suspension delrin balls that go into the upper and lower arms must have the lower ball turned upside down so that the "lip" on it is facing up towards the top arm to give the extra clearance for the slightly longer Associated front spring. Also if your kit didn't come with the Associated VSC shock that is in the 12L3 kit then you might want to get one and use it ($15). Start off with 30wght in the shock and for extra rear bite use the Associated silver spring with medium pre-load or the blue spring with light to medium pre-load. For bumpy tracks try the Associated off green spring with medium to heavy pre-load.-Dave
