I bought the large-by-huge brakes that were used on the 2006 AMG cars for the hot rod.
Mercedes caught wind of that and couldn't have some stinky old Plymouth playing in the same league. Now, they really went big with the 2007 S65 AMG cars.
Brakes from hell.



15" rotors anyone?
Pay no attention to the Renntech badge. They diddled with the engine (700 hp) but the brakes are stock.
How big are the factories going to go with these things? You do reach a point of diminishing return and I think they've found it.

 

Well the 2nd gen Vipers can stop 60-0 in less than 100 ft with 14" rotors but obviously the S-class is so much heavier than the Viper is so if they can get some really good pressure on those rotors than I don't think they'll get diminishing returns. More surface area is needed to slow the tire and the only way to do it is to make larger diameter rotors, but 15" is huge.

I can't imagine how much that car is, easily $250k +

 

I'll take two.

 

I made reference to the hot rod as a joke (obviously).
The S65 runs about $190,000 and weighs 4,600+ lbs. The big thing is that the car is designed to stop repeatedly from high speed. The V12 and all it's associated hardware puts a BUNCH of weight over the front tires. You can really slam the binders and rip the tires off the wheels with that much mass transferring up front. Throw in the Electronic Brakeforce Distribution (EBD) on top of those things and it'll haul itself down QUICKLY.

Even the 6,200+ lb Maybach will do 60-0 under 120 feet.
