my Saff has 25m lowered PI springs on it and Konis adjustable shocks set in the middle setting all round and doesn't scrap at all it's NORNALLY 5 up most of the time as well, I MUST admit it did take me 3 different types of makers of springs ie Spax and Eibach were too low @ 25m to get where I am now,and have been on the car now for 8 years and still going strong
THATS THE RIDE HIEGHT IN MY SIG below if that helps 17" wheels and they are just under the arches
