Very popular with showroom, stock racing or touring cars where the engine output is within 40% of the OE offering.
The Quest
Our company originally opened its doors in 1930. In 2001, we put all our knowledge and experience into branding our performance division, Bully Performance Clutch.
Bully was researched and designed for the racing and street car enthusiast by other enthusiasts who happen to be friction specialists. We knew what it felt like to floor the throttle in your high-powered car and only receive a moderate reaction. We also recognized the maintenance costs that occurred with repeated harsh engagements. Our main research path followed as closely as possible to O.E. pressure plate engagement characteristics to help maintain longevity of surrounding components such as slave and master cylinders, forks, thrust bearings, cables, etc On the other hand, we also wanted to considerably increase the applied clamping force to help hold the load of todays high horsepower vehicles.
So on we went with our R&D to find the perfect friction materials along with the best relationship between performance and reliability. Each of our selected components were rigorously tested to insure the highest quality for production.
Our Bully Performance Clutch kits are put to the test by many drifters in the Castrol DMCC Series, notably by the 2007 and 2008 Champion Frederic Girard. We also have many participants from the Castrol Canadian Touring Car Championship, Mobile 1 GT Sprints, CASC-OR Vintage Series, GranAm Cup Series, World Challenge Series and various Canadian Rally series that chose our products over the competition.
Friction Materials
Organic woven metal-fiber delivers smooth engagement and is the choice of original-equipment when it comes to clutch disc friction material. It requires minimal-to-no break in period. This material can overheat with repeated abuse.
Kevlar is a highly durable material that has similar engagement characteristics as organic. When segmented, Kevlar provides better heat dissipation. This material requires a 500 to 800 miles (800-1280Km) break in period.
Ceramic is a very high temperature resistant material. Its generally utilized in puck style disc for high horsepower and race applications. This material will wear flywheel surfaces faster than organic and Kevlar, especially in stop and go traffic situations.
Ferramic is an extremely high temperature resistant material. It has the best friction coefficient at high temperature. The engagement is more aggressive than ceramic and is harsher on the flywheel surface. When contaminated with oil or grease, this material can fuse to the flywheel or pressure plates riding surface. This material is only available on custom orders.
