I used to have an on road model very very similar to that, just a different company... when I used to run mine every day a few years back I was on a negative work to run ratio. I was literally putting in two hours of work for every hour of run time. I don't even know why your bothering to do this! you really should just salvage what you can off the car, the engine, servos, receiver, shocks and wheels, tally your losses, and put that chassis in the grave yard! where ever that may be... trash for some, CL and the bay for others, bottom cabinet in the corner of my workshop for me. My engine is used from time to time in various different models (and is a great little engine at that!), my servos are split, one in my jato, the other in my DBX. I dont even know where that receiver went and the wheels are long gone. And the chassis is occasionally picked over for parts for anything that might fit before I spend money on parts for my other models. It has been put to rest and now sits in a cabinet! invest in an HPI a traxxas or a associated or even a Kyosho (if you havent already done so) and do the same to yours! I do not regret it!
