I have a car set-up for drifting - and one of the best hopups that you can get for drifting is the 3Racing solid rear axle. However, YOU HAVE TO HAVE THESE Swing Shafts if you are running 3Racing (#TT01-25/LB) Alum. Solid Axle (LB) For TT-01 - the normal dogbones will not fit!
I have been very impressed with the quality of these - they are clearly well made and a good price. These swing (or sometimes called universal) drive shafts have a nice finish to them and are very durable.
They also improve the whole drivetrain efficiency of you TT01 due to their design. They give you a much smoother ride and will give you better efficiency overall.
These are highly recommended for ALL TT01 owners - I'm really happy with them!
