A one-of-a-kind signature-edition Raybestos Roush Stage 3 made its debut on Speed Tv this past Monday, July 16th. Not only is it one sweet ‘Stang, it will soon be given away in Raybestos promotion to anyone who submitted an entry on Raybestosgarage.com. However, if you haven’t submitted one yet, you still have until September 15th 2012 when the promotion ends.

The episode that showed off this beastly RS3 Mustang gave us an inside look at the build from the Roush experts themselves. Stopping power for this Roush Stage 3 is provided by the Raybestos brake package used on the Roush Fenway Cars during the Nascar Sprint races. This top of the line RS3 has been dubbed the “Monster Mustang” with an impressive 650 horses and 550 ft. lb. of torque. All of that power is stemming from the intercooled 5.0-L V8 complete with a ROUSHcharger.

Although those aren’t the only goodies this thing is equipped with. The suspension is completely Roush-tuned while Raybestos added their own chassis components. Let’s not forget about the high-performance tires helping this thing get a grip on the tarmac. The Raybestos RS3 tore up the track at the Gingerman Speedway in South Haven, Michigan for this sweet photo op among a few other sweet ‘Stangs.

Promotional Kits are still available for technicians looking to give customers a little freebie when they order any qualifying Raybestos brand brakes and chassis parts. When they do, you can give them a t-shirt featuring the sweet Raybestos Roush Stage 3. Who doesn’t like a free shirt? It’s one sweet ‘Stang so make sure you hit up the website and enter for your chance to win it.
