I have owned my XR8 for a couple of years now, but it is not a parking lot basher.
Pick up a Pico 9, with pipe, dump the stock clutch and use the Mugen clutch.
Pick up a set of Serpent 35 or 37 shore tires, get some decent servos and receiver. Trash the stock body and use either the Kyosho dome body, or the Central body.
There are a lot of options that make this car a very competitive car when set up right. I have changed just about every part on the car to either Mugen,Serpent, of Kyosho, and it will hang with my Evolvas, and my Mugen
