Camera settings for racing

Ive got one of those mini pap cameras its a lumix 12mega pixal and 18 opitcal zoom. Theres lots to play about with and id like to know some tips for when im at the gp please

fast shutter speed is what you need.
If it was me, I’d reduce the amount of megapixels used too. smaller image = less time to save to memeory card = faster reloading to take another shot
