Cutting springs is a big no-no. You'll probably get blokes arguing the point, saying there's no reason it can't be done, but realistically if you prang your car and the insurance company finds out you cut your springs then you ain't gettin' a payout.

I find a lot of people forget about the importance of legality and insurance when contemplating such mods, yet it's easily the most importat area (unless your car isn't road registered).
