Rear brake options
 

Alright guys, I am in the market for some good rear brakes for a 9.75 axle. My first question would be, are there any upgrades f-series owners do to improve their rear brakes? My next question revolves around the progression of rear brakes being offered from factory. Did the early 9.75 axles have solid rotors? The e-150 I drive at work (2009?) has vented rotors. Any help would be great in finding the available brake/rotor options to look for at the local scrap yard. This is for an upcoming project. Thanks!
