I have got to tell ya this car is great, I have been paying around with setups and overall am happy with the Chad Bradley setup as a baseline. The lighter oil I go the better the car feels on our rutted up track. A lighter rear sway bar is the first thing I can suggest to help out the car and I am running 25 in front with 20 in the rear (losi oil). Good job mugen on this car , glad I did not get the K Car. I have over 2 gallons on the car with no breakage!
