If you haven't been to Horsham Developments before I'd highly recommend them for any work.
Jez and the guys there did a whole plethora of work on my Zed earlier this year including brake fluid change, new discs, new pads, clutch fluid change, gearbox/diff oil change, fitted plenum spacer, UpRev... etc.
Did a fantastic job and I felt it was well worth the drive from South Wales to use them. Very happy customer of theirs.
