Hello, anyone here have experiences good or bad from Jamex lowering springs on their A4? Have seen a set cheap. Is it right standard Sport set-up is 20mm lower than standard? Also anyone know who's springs they are. I figure that they must be pretty tired now after 112k but I don't want to maker the car too hard as I may be going up to 17 or 18 inch wheels and I dont want my teeth falling out over every bump! Also the car has probably sagged to more than 20mm lower so fitting -40mm (over standard, -20mm over Sport) probably isn't going to go that low? Aswell as the ride I have speed bumps up my road and a dip into the car park at work to worry about.
