Has anyone installed a proportioning valve on their ABS e30? I need to install my wilwood one this month and am wondering what other people have done as far as line routing, valve location and mounting..etc. I would especially love to see some pictures. My first idea is hand bending double-walled hard line and mounting the valve to the driver's side to the engine bay with 3M or a rubber bushed L-bracket. I intend to mount the valve between the MC and ABS pump, on the rear circuit of course.
