I have ordered the following,

engine heat sink
alloy main shaft
teflon bearings
oil shocks (which springs do I run?)
front and rear sway bars (will I need the carbon upper deck?)
HPI wheels and drift slicks

I have also just impulse purchased a tamiya Super Stock TZ motor. The guy said it would work with the current ESC/transmitter I have that came with the car as part of the EB series. I hope he's right yeah? I'm also hoping it is faster than the stock 540!?

I really don't want to change the ESC if I dont have to.

I'm also wondering about what the pinion is and what size I should get if it will help.

Will I or should I muck around with the gearing?

Thanks again guys!
