So I have always been curious how fast one can actually stop if you are going 60mph and just slam on the breaks.

I am considering taking my benz to a huge parking lot and accelerating to 60mph.... and then just slamming on the breaks and holding them until i stop.

I have a few questions.

1. You think this will totally ruin my tires?
2. You think this can damage my car somehow, like the breaks?
3. Anything I should know before doing this?
4. Has anyone done this before?

Anyone have any thoughts?
 
You probley will put a flat spot on your tires. I don't think you will break your brakes but it probley isn't the best for them.

Not if he has ABS. Depending on how long it has been since you have had your rotors changed, you risk, warping your rotors, and alot of wear on your brake pads and fluid.

Do it, and learn the car control aspect of it, but I wouldn't do it more than 3-4 times. Let the car cool between each hard brake, and realize in advance your braking capabilities will degrade on each succesive stop.

Depends on the type of car you have. You could always look up the 0-60 and the 60-0 specs for your car. It shouldn't do too much damage. If you don't lock your breaks, you won't place a single flat spot on your tire. Your car doesn't stop very well if the tires skid on the pavement. Your car stops much sooner if it continues to rotate (e.g., pumping your disc brakes, using ABS). If your car has break assist, your face will hurt (it stops that quickly).

When I installed my Stoptech rotors, they included details on how to "bed in" the rotors and new pads. For that procedure, you drive up to 60-70mph, then brake to 10mph (NOT stopped) as fast as you can. You do this 10 times, and then let the rotors cool, and then do this 10 more times. In this case, the point is to heat the rotors, and then evenly spread brake dust onto the surface (this would happen naturally as you drive, but not necessarily evenly, especially if you come to a full stop).

As long as your rotor thickness is within spec, they can handle the heat, especially if you're only doing it once. As someone mentioned, if the tires do not lock up (i.e. your ABS works), you won't do anything to the tires themselves. I didn't actually rely on ABS, I stopped just slow enough that ABS didn't kick in.

I did this at my local mall parking lot after the mall was closed on a Sunday evening. If you try that, be sure to circle the entire mall once to see if anyone happens to be hanging out in the lot. It's not legal to drive that fast at the mall. :)
