Anyone on here sliding 318 bmw's?

Is it possible?! i just bought one and i was thinking of turning it into a cheap slider just to get the learn the basics of drifting! Car will only be used on track and i dont want to pump much money into it so i was just thinking of stripping interior, welding the diff and hopefully source a cheap set of coilovers for it! Failing to source cheap coils, would it be any use cutting the springs?!

Also is there any fuse or relay for airbags, or what is the best way of disabling them?

Any advice would be greatly appreciated!!
