The Stage 1 and Stage 2 cars are essentially bolt-on upgrade packages, with Stage 1 starting out with the basics: a full body kit upgrade, 18in wheels and sticky tires, new headlights, custom badges and a stripe kit. A wide range of interior kit can also be fitted at Stage 1, including short shifters sill plates and more. Also available optionally are exhaust, lowering kit and a big brake upgrade. Pricing starts at $5,952.
Stage 2 steps up the Stage 1 package with the addition of a Roush custom suspension and wheel-hop kit. Better launches and twisty-road handling are the result. The same optional upgrades for Stage 1 cars are also available for Stage 2. The Stage 2 kit starts at $7,326.
Roush revealed last month that its range-topping 427R Mustang will be the first to feature the company’s new ROUSHcharger supercharger. This boosts power of the Mustang’s 4.6L V8 engine to a healthy 435hp (325kW) and 400 lb-ft (542Nm) of torque. This is also the first time Roush has been able to offer a supercharged vehicle at the launch of a new body style.
Under the hood customers will see many differences in the 2010 427R Mustang compared to previous years. One of the biggest changes is that the long air induction tube that wrapped around the engine was eliminated making a much cleaner overall appearance.
The intercooler reservoir has more than twice the volume of previous generations, and the intercooler itself is a single core cross-flow radiator which means more efficient cooling. It’s also substantially larger than on prior model years, and is now raised higher off the ground which should offer much less potential for road debris damage.
Although much of the car’s V8 powertrain components are a carryover from that used on the 2005-2009 Roush Mustangs, the appearance and the quality of the modifications are claimed to be greatly superior.
Changes to the regular Mustang’s exterior include a new front fascia and front splitter, rear fascia, side splitters, and a three-piece rear wing. The vehicle rides on 18in chrome wheels with high-performance Cooper Zeon tires. Bigger 20in wheels are an option. Finally, the 427R also gets the Roush-engineered suspension kit and wheel hop reduction package. Pricing for the 427R upgrades starts at $14,156.
