first off if you're trying to drift a nitro, don't bother...too much of a PITA.....the TC3 is THE car to drift...cheap....tough.....and easy to setup.....
shaft drive is the way to go for drifting, belt is better for racing and keeping smooth lines......
setting up is easy....
1st....SLAM IT TO THE GROUND...lower that beotch....you do need a smooth surface to drift well, so lower it as low as it goes......set the droop, change shock positions, and set your spring tensions so the car sits low
2nd get the ABS plastic drift tires...I forget the pipe size but you can buy 2 sets on e-bay for 10 bucks usually....you'll need a set of rims to mount em......
3rd....rear sway bar as stiff as possible...loose the front bar altogether so it won't break loose as easy......I think it's the stock blue springs all around, maybe use stiffer in the rear to break it loose easier.....I use 30wt oil in fron shocks and 40 in the rears.....
4th...loose any "bad ass" modified motor you put in and get a good stock motor (more torque)...and I run a 25t pinion and a 76t spur.......
5th....get a solid axle in the front.....CVDs and steel outdrives......
I never centered my pack but I did balance the car on a station (not necessary but does make drifting a lil easier)
you can cheat and put foams on teh front and drift tires on the rear to get teh hang of letting the rear swing around and use throttle control to keep it in check, but it's not really the same effect...the car still hooks up and moves fast but you can loose control real quick like a drift car can.......
when you drift you are not going to be hauling ass....you want the wheels to spin and the game is to keep it going where you want while it's slipping and sliding....fun stuff but don't expect to just set it up and be a drift king......I highly recommend anyone who races 1/8 scale offroad to setup a toy to drift for fun....you will look at your lines on the track in a new light.......
