yer dont do it on your own even if you think you can do it incase the car falls. my bf was working on a scrap corsa in me garden and was on axel stands and he come in to a get a drink, next minute the car crushed the axel stands! if he hadnt of come in for a drink hed probly be dead now try never to work on a car underneath on your own cars looking good tho, i like those wheels black look alot better than silver!
