I have spent over a hundred hours on this game, thank you to whoever made this work of art. Literally everything is perfect, from the song to the actual driving of the game, which is remarkably well done for a flash game. As far as I know, I am the fastest person in this game by quite a large margin, and I hope that the tips can help you all be much faster! I don't know and don't desire to hack this game, I have proof of all records below through screenshots and such. As for my records, here they are:

Easy Track

PR:94.1 seconds

Best Lap:31.0 seconds

Car: AE86

Hint: I bet i could go faster than you backwards ;)

Hairpin Track

PR: 64.6 seconds

Best Lap: 21.1 seconds

Car: AE86

Hint: gas in, lift on apex, gas out, you just need lots of skill for this one

Good luck to all the racers, and thanks for making such an awesome game!
