Try to get your setup good before you drive. Minis can be absolutely horrid and no fun if you dont have a decent setup.
Tyres and shocks are probably the most important thing. You need to build the shocks to limit the droop. You may need to put o-rings in the shock body to do that (but dont use silicone o-rings because they swell up) some of the mini shocks already have a shorter shock body to limit the travel.
Also get the mini low to the ground.
Good Luck, and dont worry minis are more than happy to jump over things (they just dont always look the most co-ordinated doing it), and if you are with friends.... over each other
