Can anyone please measure for me the height from the floor to the underside middle of your arch on your standard spec alloys and tyres. I am thinking of putting standard springs on my golf with my 18 inch alloys. Just want to work out how much gap would be left. Perhaps you already have a similar setup? My tyres are 225/40/18. As it stands, the car is too low for my liking as its an everyday car that I need to use on these damn speed bumps around here!
