He goes on to say if you're driving 10, 20, 40, or 60 MPH it's going to take the same time/distance to stop your car. That's absolutely correct, but the reason people upgrade cars to make 400 WHP is not so they can go the same speed as they went in their stock car. It will DEFINITELY take bigger brakes, better tires etc. to decelerate from 150 MPH than it does with your stock car at 60 MPH.

A lot of other people have mentioned brake fade, which is a condition that you will rarely experience on the street unless you do a lot of canyon carving. However, if you do ANY track time, it's a VERY real concern that needs to be addressed. Stock brakes aren't designed to dissipate the heat generated on the race track, period. On my local track, decelerating from over 135 at the end of the main straight to go through turn 2 at 80 MPH, then accelerating up to 110 going down hill into turns 3A and 3B at 40 MPH over and over again for a half hour at a time will most definitely cause stock brakes to fade if not outright fail. So if you have a stock car that might only be able to get up to 100 MPH on the main straight it's not nearly as hard on the braking system to decelerate to 80 to go through turn 2, and if you only get up to 60 or 70 going down the hill into 3A and 3B you may be able to do that all day without your brakes fading.

Just sayin' having a lot more than stock HP can certainly mean you should upgrade your brakes if you aren't driving the speed limit...
