Master the IA-5 Corkscrew on Tokyo R246 in Gran Turismo 3: A-Spec using the Dodge Viper GTS. Achieve Gold with times of 0:23:900 (G), 0:23:300 (S), and 0:25:000 (B).

  • Car: Dodge Viper GTS
  • Track: Tokyo R246
Walkthrough
  1. 1
    Drive up the hill towards the tyre marks.
  2. 2
    Brake just as you start to descend the hill. The downhill stretch before the corner makes the brakes less effective, so early braking is crucial.
  3. 3
    Move slightly to the left in preparation for the upcoming turn.
  4. 4
    Take the kerb route through the corkscrew.
  5. 5
    Take the final turn out wide.
  6. 6
    The left corner after the corkscrew lies after a steep downhill and has a shallow bank, so watch for unusual car movement.
  7. 7
    Finding the best line is difficult; check the demo for assistance.
Tips
  • Early braking is essential due to the downhill section reducing brake effectiveness.
  • Observe the demo to learn the optimal racing line.
  • Be cautious of unexpected car behavior on the shallow bank after the steep downhill section leading into the final corner.
  • Gold: 0:23:900
  • Silver: 0:23:300
  • Bronze: 0:25:000
