The TT02 is a reliable, consistent, drivable car. It is a platform you can learn on. But it's not good for racing in "open" classes. There are $100 cars that have all the features, caster, camber, easily swapped gearing, metal body shocks, oil filled shocks, anti-dive, adjustable toe, adjustable camber gain, adjustable roll centers... which are things that are essentially out of the question for TT cars.

So what you want to hear. Buy a good steering servo. Something with less than 0.1 second 60deg rating. Spend $30 on some yeah racing or 3 racing oil filled shocks. Spend $25 on a bearing set. Buy a heavy duty servo saver (Tamiya's is good) which is $10 or so. Spending more money is shoveling good money after bad. This is entirely about making the car controllable and long lasting, so you can learn to drive. The pogo sticks it comes with make the car less consistent. the stock servo saver is to soft to drive straight really. And bearings remove a lot of slop from the wheels so the car goes where you want it to go.

If you want to get actually competitive, you really need to buy a different car. "the parts to get those features" are available for the TT02, but you do not want a $1000 tt02. And buying carbon shock towers, TRF416 arms, adjustable roll center parts, gearing parts, oil filled diff, spool adapter, universal joints, metal drive cups, swaybars, and more quickly ends up the cost of just buying something capable to start with.
