From the start to the finish:
1. Get a Nissan 350Z or Silvia
2.Get stage 3 parts (The suspension is the key. With stage 3 suspension you willdo wheelie, so in normal drag race just remove the stage 3 suspension otherwise your car will go wheelie and fly and crash)
3. Soften the suspension and lower the ride as much as possible (Just pull all the bars above"ride height" to the left, and "ride height" of course, in the suspension page of tuning)
4. Shorten the gear ratios to 1/4
5. Max out the power of the engine (2nd and 3rd bars in the engine page, somethingcalled "start boost" and "end boost", forgot)
6. Then you will make 400m of wheelie everytime, easily.
