Since I now have a tuned V6 engine. I improved the brakes by fitting Wilwood 4-pot calipers on the front with greenstuff pads, vented disc and improved linings for the rear std drum brakes. I don't like the standard 'plumbing' system ie rear brakes plumbed in series. Has anybody improved this setup eg by fitting twin master cylinders or plumbing in a different way with a bias valve? I don't yet want to go to the expense of fitting rear disc brakes.
