Remember, he is going to larger brakes. The 11 inch Mopar drums stop better than the 10 inch. Some say about equal to disc. So he is going to have better stopping no matter what drum is picked. He mentioned that the heavier (finned) drums are twice the price of the lighter drums, so that is an issue. As Mike pointed out, the contemporary brake shoe material is more effective too. As a police or taxi use -- with all day heat buildup -- I'd lean toward the finned, but as a weekend driver the non-finned should work okay. My 2c anyway. :) Gary H. > -------Original Message------- > > All I remember is what my grandfather told me. He told me that Buick > put large fins on all front drums of the 1966 (I think) cars.
