Hey everyone, I can't win a gold medal in SAND CLIFF track. Help! I've tried this track like 2k times already and my best time is still 0.9s off the golden medal. I've already completed this track withouth slowing below 112km/h the full track - including the very tricky last checkpoint. I've tried to jump before the tricky curves everywhere where this is possible and nothing. And I see no solution for this as my time is still around a full second OFF the golden medal time. Likely impossible or there must be a hidden trick or cheat to bypass this circuit. I was able to score a gold medal on all track but on SAND CLIFF. If someone knows how to do it, please post here. Thanks a million!!!! P.S. I have a Nokia 6250 cell phone and this is the game "RALLY 3D".
