Having participated in two race nights with my new mini - I'm hooked.

Some of the Lessons I have learnt already:
Don't turn too too tight - you can roll.
Don't turn too tight, the inside wheel lifts and the diff unloads thus slowing you down
Don't turn enough and you won't make the corner.
Don't use a One-Way diff - HELP NO BRAKES !! (only joking)
Don't take it too seriously - you'll only get disappointed
