Hi Terry, have you ever adjusted the ride height on your 575M?
After last weeks trackday and with next weeks trip to the Nurburgring in mind, I've decided to lower mine 15mm all round. Usually I keep her wound up to the max to cope with the ever increasing numbers of speed bumps here, plus don't really push it on public roads anyway. However it will be interesting to see how this effects the ride quality on the 1800 mile plus round trip and if there is a discernible difference on the track.
I'll try to remember to take a photo or two of the lowering process next week.
