Why would brakes have any effect on your HP? Your car will fractionally weigh a triffle more so your speed will suffer but the moter will still be making the same hp as it did before.

i'm pretty sure you will lose some rear wheel horsepower, your creating more drag which should effect horsepower numbers.

You will loose a few horsepower. I watched an episode of dream car garage where they put a bige brake kit on a RSX type S that lost I think 8 hp. Becasue your moving the weight further out of the center. I cant think of the name for it... But its the same principle with the flywheel and rotating assembly. But anyways its to bad, but its not very much and having better brakes is sooo much better. You will cut down your stopping distance.
