Rednck21 I don't like that feel either. I try to dial in as much steering as I can without drifting the back end around. It's not always the easiest thing to do especially with the amount of power these e-buggies have. I do agree though your sway bar combo seems wrong. Instead of swapping them I would go silver front and rear first. Then if you can drop to the softer front because the hardest rear one is going to free the back of the car up and feel loose like you said you don't like. Also lowering you current limiter or epa might help. I know it has for me.
I'm trying the upper hole in the rear hub and the softer black springs on mine. I started with the black springs on the rear but felt like I had to use too much preload and the rear was still squating too much so I went back to silver before going to the track. With the rear hub change I didn't need as much preload and I'm not as concerned with it squating because I really want it to plant the back end on corner exit anyway. Problem is I'm running this as a second class and that hasnt given me a chance to try any setup changes at the track and I'm not gonna be able to race the next few weeks because of family stuff so I won't know for weeks if I am making the right changes or not. I can only go by my 3 years racing the RC8 nitro.
