Yeah no probs Matt - As I said in the pm to ya just before. TT01 seems cheap to begin with but you pretty much have to upgrade every single bit on it to get it up to par with the better belt-driven cars. My car has only just finally come good, I have done the following to it.
- Full alloy conversion kit of driveshafts, propellor shaft, upper and lower arms, diff mounts, battery posts, steering posts.
- Camber adjustable arms
- Removed the drive shafts and replaced them with locked steel alternatives (stops them bending when hitting stuff)
- Replaced the 2 Diff Gears, rear is a fully locked diff, front is a one way LSD.
- Replaced the receiver with a 2.4ghz System
- Replaced the motor and ESC with a Brushless setup and LIPO Battery compatible system.
- Replaced all the plastic bushings with ball bearings.
- Replaced the steering servo with a high-speed metal geared one.
- Replaced the steering arms/system with a racing steering system.
- Added weights to the front end.
- Replaced the shocks with Oil Filled dampers with Soft springs.

Have spent about 800 bucks now I rekon. A fully kitted belt drive would have cost maybe 500-600 all up?
