im sure you ask this sort of question every week?
40mm will barely be a drop, youll want to go lower after you buy 40mm and see them on the car. if your spending £120 on springs then fork out another 40 and get rokkor coilovers.
there good for what you pay for mate! for the money i couldnt fault them, obviously there not going to be in a league with the top brands but there a hell of a lot better than just lowerign springs! they can go pretty damn low too :approve:
