OK, so maybe Roush can’t design an entire car. I have to give the Ford engineers some credit. The Roush team, though, has created a gorgeous front fascia and grille that extend the front end and sharpen the soft curves of the stock model. Roush has also added new hood vents and an optional hood scoop.
RS kits are for Mustang V-6 models; RS1 kits focus on the turbocharged Mustang EcoBoost; RS2 uses the naturally aspirated 5.0-liter V-8; and we can assume that, like with previous Roush Mustangs, RS3 adds a supercharger to the V-8 with various stages of power available.
