The best Dragster is the Ford Shelby GT500. Put on all the best performance parts you can afford. Remember, you need a lot of speed and traction. After you start setting new track records you will be invited to race Karol Monroe the Drag King. Here's a following parts that you will need.

Power: LVL 3
Traction: LVL 4
Aero: LVL 4

Try at least put your car on Aero: LVL 4 because it will make the car go more faster and easier to make the car do a wheelie with LVL 4 Traction. Any kind of Stratospeed body kit style will work and use the Gentra Style 403 spoiler for better Aero in any size.
