Yes! That 6.2L AMG engine sounds SO GOOD at 7200 RPM and WOT, plus it's normally aspirated. No turbos to muffle the exhaust.

507 HP sounds wimpy these days, but it hauls the mail pretty well.

Just install rear discs and leave the C-clips in place. The caliper does an excellent job of retaining the axle/disc combination.
