they probably would be an good replacement. but its not an upgrade. with larger tires it increases the rotating mass which is a lot harder on your brakes...it makes your truck seem like it weighs twice as much so twice the force on the brake pedal is needed to stop those monster tires.

My JDM GEN II has single piston front brakes (stupid), so that is on my "to do" list along with stainless lines. I didn't know powerslot made rotors for our trucks. that is an excellent way to go to reduce brake fade if your brakes get hot!

Stay away from the cross-drilled/slotted rotors I see all over ebay for our rigs. cross drilled rotors is the worst thing you could put on your truck if your brakes are going to be taking any kind of heat. they crack and can fall apart in extreme conditions...and they don't offer any more cooling than regular slotted rotors.
