Fellows, If you cannot stop and kill yourself(selves), you will not be able to enjoy your 300. I purchased a 57 C from Kent Hurt in 1989 and he had put disk brakes on from an 1971( I believe) Imperial. I can lock up the front tires at over 140 miles an hour. This car will not only stop, but it will not fade. I have other 300's and they cannot stop more than once from a hard run. Then the brake fade will kill you. George Riehl indicated to me that he ran regular brake linings in combo with heavy duty metallic linings, split one regular, one metallic per drum. He said he could make a stop with his J at over 140, hard to the wall and not experience any brake fade. I am going to try this on my Ram K. If it does not work, the disk package goes on! I love to drive fast and stopping is a prerequisite. The life you save may be your own! Quentin Smith [Non-text portions of this message have been removed]
