I'm doing a C5 brake upgrade on my 56 Nomad and I was wondering if any of you have used the Power Stop Z23 or Z26 brake pads. We figure that the car is about 1000 Lbs. heavier than a C5 so we are leaning towards the Z26. What don't want is a pad that needs to be heated up to stop the car. Not Building a race or rally car but we do want the best brakes we can get out of the system.
