Looks alright, although I doubt you would win any drag races with those rear wheels. You would have no torque due to the weight of those muscle machine wheels and the extremely hard plastic provides no grip.

Here's an extended bit drag car by crazydave:

You can see by the video that the wheels are extremely critical at those speeds along with the weight of the car. He added four zipzap se batteries to achieve 4.8v to the pcb. This car looks a lot more proportional to a real drag car and performs like one also. My suggestion is to find some better wheels before you start modding the chassis. What good is having a drag car that spins out and can't even finish a race?
