Most that do the swap, swap front and rear. Dont think he'll swap just the rear to keep 4 lug front. Rotor surface area is where better brakes come in not pad suface area. Look at any aftermarket brakes and they all use tiny pads and larger surface area rotors. When your car get going....I wanna see how long it takes you to upgrade to rear disc.

Also with rear disk you wont keep the 90/10 ratio for the brakes. Add a adjustable prop valve and lean on the rears more. Aerospace and Strange has dual rear calipers for looks? Why didnt they do dual front calipers? I mean 90% is the front brakes right? Dont buy stock in EVERYTHING you read on the intraweb
