Hydroboost braking systems
As a person who has installed about 4 or 5 of these, .....THEY ROCK! I have installed them on cars with big aftermarket brakes and on cars with stock front brakes(stock disc for now). Either way the amount of pedal effort dramamtically decreases while the amount of stopping power dramatically increases. For a pro touring car, it's perfect. I have done a couple of pro touring style cars with hydroboost and it just complimented the package.
