The best, period: VAC's S54 7.25" clutch kit- a tremendous piece of engineering: The best flywheel and clutch kit money can buy, bar Nothing.
Used in infamous 1000+ WHP turbo M3's, Custom Supercharged builds, full on race wining touring cars and other exotic projects where the ultimate performance without sacrificed is demanded.
Linear pedal effort similar to a OEM clutch with a more positive engagement... Gear changes so smooth it feels like a new transmission; unbelievable.
Utilizing the same technology found in Formula 1, the unique Carbon/Carbon clutch assemblies from Tilton offer an unparalleled blend of high-torque capacity, drivability and long life.
The flywheel (now only used for ring gear / engine starting) is machined from premium Billet Steel and non-load bearing, eliminating any doubts racers have about Billet Aluminum units while still offering ultra-low inertia and just enough stored energy to work well with supercharged S54s.
Tiltons Carbon-carbon friction pack has all the best characteristics a clutch can have; the smoothness of organic with strength and power holding that can easily exceed sintered iron. An excellent choice for any super high performance build. Linear engagement characteristics similar to a street clutch with extreme heat capacity of the carbon matrix plates enable this clutch to be easily modulated/slipped without overheating and failing as others can. This characteristic also helps to reduce stress placed on other driveline components. The combination of the Carbon/Carbon clutch's extremely low inertia and the lightweight billet flywheel produces amazingly improved acceleration and very smooth high-rpm shifting as the syncros can match speed in the transmission much faster. The Tilton Carbon/Carbon clutch assembly also includes two additional pressure plates that compensate for wear, extending the life of the clutch before a rebuild is needed.
Our VAC adapter kit allows the standard BMW master cylinder to operate Tiltons Hydraulic release bearing directly; offering low effort and perfectly linear engagement. There is no longer any clutch fork being used, eliminating this weakness and potential failure point.
Smooth like a street clutch-bites and holds like a pure race clutch; Carbon/Carbon 7.25" discs offer a clutch that can slip when needed and grabs harder the hotter it gets.
Extremely low mass compared to any traditional clutch design, this low-mass arrangement revs extremely quickly yet is very street-able and user friendly. Allows transmission syncros to come to speed super fast; gear changes become lightning-quick for domination on the race track.
100% carbon floating discs do not wear like typical friction materials in lesser designs. This offers quiet, long life (much higher than other materials) that will-not chatter, make odd noises like ceramic or bronze clutches, or have 1/3 the life of a Feramic clutch.
Are you in love so far, but concerned with cost? Lets show that this is actually a value if it meets your needs:
-Up to quadruple the life of other units
-Quieter than many others of similar muti-disc design
-Smoother than others
-MUCH lighter than others
-Perfect for street or full race, and everything in between
-The highest power handling available
-Adjustable & rebuildable!
In the end, its high initial purchase cost is offset by its performance, and rare need of replacement or service. Would you rather buy 3 or even 4 clutches and clutch jobs that don't perform as well, or 1 ULTIMATE performance package?
