I think you meant to say 160 lbs dropped from car....
Our Porsches , Mercedes , Jags and The Acura NSX can be ordered with Ceramic Composite Brakes for around 10k.
I always thought it was a waste of money for the street because no one brakes hard enough to require them on the street.
Then I picked up one of the rotors to an NSX ! WOW! they are light !
