Thanks for the great advice!Press the button right before UPGRADE... the one that says SELL. I haven't seen one competitive at any level or distance.
It's a game, I play it for fun and I'm gonna use the cars I like, I don't care about getting to the top of the leaderboard.
....My friend is running a fully upgraded lambo (Lvl 6 I believe) and he's only hitting 8.6's right now. Is this possible? or is this some kind of hack?

, or tuning advice
