This is my TT02s, will be using it in our Tamiya Cup next year. The best upgrade I've done is the alu steering, the stock steering has a lot of slop, now there is almost non.

Tamiya hopups so far on the car;
- Alu Sterring
- TRF Shocks
- Alu shaft
- Alu motor mount
- Speed gear set
- Front drive shafts from a 416 (original shafts tend to come out if you hit something hard)
