John, the Willwood pads were a shitshow to begin with, needed to be bedded in and the first corner out of the garage the car 'slid forward with full brakes, frightening. Anyway, after they were 'conditioned they stopped ok, well better than the twin pot calipers. The hydroboost finishes it off for me , very similar to a passenger car performance, not a bit heavy truck. I purchased a Proflow vac pump to run as a spare before I went Hydroboost, cant find it, so bought another smaller vac pump as the spear, but I only have cruise control and clutch booster under vac, so can live with the chev vac pump going out.
