Well we have been doing some research on the car to make it fast.
This mostly comes from Knowledge Performance and my ass.

new Intercooler piping will get you 15hp
C16(race gas) plus a tuned Utech 35-55hp
The brakes overheat like a bitch(I left foot brake though) so maybe Carbotechs are needed
Stock tyres get greasy at 135-150 degrees
The DCCD works best in auto for racing/autocross
A bigger rear bar would help the car on slower and sweeping corners(it understeers bad there)
This car Kicks Ass!!!

Ill add more later as I remember/hear stuff
