You wanna run all four tires made from ABS or PVC. You need 2 inch diameter piping if you want to make your own. It's pretty easy to do, but kinda labor intensive if you've just got a hacksaw and no power tools. If you're lazy like me you can order them from
http://www.sushircdrifttires.com/I think it's like 12 bucks for 4 sets, free shipping to the US.
If you slide your 240, drifting an RC car will come naturally to you.When i first started drifting an rccarthe hardest part was forgetting which way was which with the car coming towards me. But honestly within a couple minutes i was drifting just fine. Not necessarily the case when it came to my friends. They either just "got it" or they didn't.Not surprisingly it was my friends whofollow drifting and understand how it works that did just fine. My other friends who arn't so much into cars, couldn't drift for crap even after 15 minutes of trying.
By the way 12T is a pretty low turn motor. My TT01D came with a sport tune which is like 27T or something. High turn motors are usually 37T or 55T.
