The bigger brakes and better calipers are nice but I hate the sealed hub wheel bearings. I have gone through three in the last six years on my Blazer. They are more than ten times the cost of a set of standard wheel bearings. Even used they are $50 each around here.
I considered building a bolt on hub that uses standard Timken wheel bearings but just don't have the time to build and engineer it right now.
A bolt on flange with a spindle shaft that matched the early GM drum brake hubs would be the best. The drum brake hubs are easy to find, are very strong and you can get 65 to 82 Corvette 11.75"x1.25" rotors that will slip right onto them unmodified. They are what the 68-69 Z/28 trans am race cars used in the JL-8 brake package to dominate the series. The rotors are only $35 each at NAPA for American made parts too.
Use these rotors with an LS1 F-body front caliper assembly and you are good to go with common off the shelf parts and no more lousy sealed hubs.
Almost forgot. The best thing about using the C3 rotors is that they were designed to work with 15" rally wheels so you do not have to run 16" or larger wheels or rims with special FWD offsets. The stock 15" wheels on you truck or Blazer will work as well as the 15" drag wheels you may have too.
