I have "only" 275 width rear tires, had to get on the brakes hard and the rear wheels skidded for about 20' (actually left marks on the road!), so I made a pretty big adjustment. Now I get some front end dive. It's probably okay now. At the beginning they didn't really have a lot of output but since they have a couple thousand miles on them now the output is up. You don't really use a ton of brake driving on mostly 45 mph roads and having a stick shift, especially this one because it compression brakes well. On my other manual cars I get a wear rate where my brake pads would wear out in about 110,000 miles, of course the winters kill the rotors before you can get there usually.
