If you're to make your TL-01 just a bit faster, why not spend some money on a racing bearing set. You can consider upgrading motor or esc, but they will be much more expensive than simply get a set of these and give you an instant performance boost.
This is the first upgrade for the tl01 chassis.
Before you'll take a stronger motor than the stock I raccomend to install in your car the full set of ball bearing.
You'll have less friction and more top speed.
You will take more run time.
