Ford tuning specialist Roush recently revealed a new package for the 2013 V6 Mustang they have dubbed the Roush Six, or RS package. $4,000 gets you a mean-looking Mustang with a lowered suspension, Brembo brakes, a front chin splitter and 19-inch painted alloys. The aim of the modifications is to transform the V6 into a GT, however the changes are purely aesthetic in nature; the wheels may have been sourced from the V8 but there's no upgrades to the 3.7-liter V6 powerplant.
