TTP-Engineering has paired up with QuarterMaster USA to bring you the very best in twin disc cerametallic clutches.

Made in the USA, these lightweight push style clutches use NO WEDGE COLLAR like the stock pull type and Exedy twin discs. This will ensure that the throwout bearing will not pop out of place at high RPM and torque levels. Victims of this ourselves when using the EXEDY twin, the TOB retaining clip would pop out, rendering our clutch unable to shift about every 2 passes or so at 700+whp.

That is NOT the only reason to invest in this awesome clutch. The Quartermaster twin cerametallic clutch is ONLY 18.6LBS! That is about half the weight of the stock clutch and flywheel unit and also about half the weight as the EXEDY twin and triples!

What does this mean? It means not only is there less weight the engine has to use up whp trying to spin, but also that its smaller circumference clutch pack has a lower moment of inertia which equates to a super fast revving engine with an ability to shift lightening quick!

The Quartermaster twin from TTP-Engineering is a vented clutch with twin cerametallic discs which allows for fast cooling and light weight discs. Quartermaster's patented hydrailic release bearing is fed by a stainless steel line to improve clutch pedal feel and more directly transmit the brake fluid to the HRB piston, when disengaging the clutch.

We are currently R&Ding for Quartermaster and have managed a 1.57 60' launch on a heavyweight street car complete with A/C and power steering. We will be transferring over this clutch to our 2010 season drag car with some upgrades we are testing in the hydraulic system. Currently the street car has run 10.1 @ 144mph at 3165lbs on a stock displacement 2.0L and stock 5sp Evo VIII transmission.

We have added the Quartermaster line to our site with limited time pricing so if anyone is interested in picking one up, let us know!
