Usual stuff to get for high speed action.
!. Foam tires (never use rubber tires cos they will bloat up during high rpm which in this case would reduce your traction alot.
2. An at least 7turn motor
3. An ESC that can handle 7 turn
4. Match cells (6, 7, 8, 9 or even 10 you choose)
5. IF i were you, i would just go towards brushless ESC n motor. Schulze and Hackerz make some wild stuff out there.
