For the people who say they don't like the hydroboost, what experience are you basing your opinion on? I run gen 3 viper calipers with 14.25 rotors and the cobra rear calipers with 11.75 rear rotors with Carbo tech pads, srf fluid and braided lines. Down the straight at 130 and braking with ease to turn one at Lime Rock. I watch others struggle to slow down. I couldn't be happier with these units. However, I'm using new Hydratech units in all my applications.
