Hydroboost braking systems
I ran one on my built 454 with Baer serious street 4 wheel disc brakes. Before with the standard vacuum booster it felt like the brakes really weren't coming on the way they should, with the hydroboost the brakes start working the second you touch the pedal, stopping action is right there, no pedal drop like a vacuum system. Installation is simple and straight forward. The only downside is they feel more like non power brakes from a pedal feel but stopping power is 10x better. The front/rear bias needs to be spot on or you'll lock up the wheels in a panic stop although they have great modulation once you get the feel for them.
