Hello all, my Mk2 16v is still a project in progress unfortunately, but would like to crack on with it. The load valve on rear axle is fubar'd, and I am replacing all brake lines (maybe running these trough the car rather than under, haven't decided yet?). Has anyone fitted an adjustable proportioning / bias valve instead and if so what did you use?. I have 288mm brakes up front and standard rear disks with mk4 calipers on rear. Cheers all.
