mate, you're asking for trouble with that question on this forum...
It's totally frowned upon, and not at all condoned by rollaclub.com
It's not a hard thing to do, if it's beyond your capabilities, chances are you don't understand how it'll f@$k up your car's handling too.

Best of luck with your ride.
