I didn't try to look for a weight savings on my brakes. The front rotors alone are 27 lbs each.

When I picked this stuff up 7 years ago there were no big brake kits for old Mopars so I built my own.



They do fill out an 18" wheel nicely.




The stopping power is impressive. There is no fade unless you ride the brakes for a mile or two. The stops are smooth and short.
After driving with modern brakes on an old car you won't ever want to go back.
