21lbs Dual Mass change kit for a 28 Spline 6 Speed
Steel FlywheeL/ Kevlar disc
JMTC’s MINI Cooper S Solid Flywheel Conversion Clutch Kit is a direct replacement for the OEM dual mass flywheel and clutch kit. Our clutch and solid single mass flywheel replaces the entire OEM Dual-Mass Flywheel and clutch set. All of our flywheels are interchangeable with the OEM clutch sets and all other OEM components. The steel surface can be refinished on the steel flywheel and the friction area can be replaced on the aluminum flywheel.
Why upgrade/convert to a single mass clutch?
Dual mass flywheels are designed to transmit less engine vibration to the drive-line so they do reduce some of the jerking engagements. But they have to be tuned to the power and torque output of the motor so they usually work reasonably well until they are abused, improperly engaged, or engine power is increased. However this is not the rule and sometimes they do fail prematurely, they are also a consumable and can not be re-used.
DMFs are also a two-piece flywheel so the friction thickness is substantially reduced which can cause the friction area to superheat and glaze due to inadequate heat absorption. Also since the friction area is designed to absorb the engagement they are made of two separate pieces with a long spring. This internal spring has been known to break and/or the two halves of the flywheel apart. This can leave you stranded and it is an all too common occurrence. The DMF clutch system is designed to last the 100k miles however they do not and even under normal driving fail around 60k and sometimes they fail in a way that leaves the car instantly in-operable. Leaving you stranded and unable to limp to the repair shop like you can with a strong traditional clutch even after it has failed.
Unlike the OEM Dual Mass Flywheel the JMTC flywheel can withstand any driving condition without the worry of a catastrophic failure. Our flywheel has a performance proven traditional single mass friction surface that is 4 times the thickness of a dual mass flywheel. This is good for a number of reasons, there is no way for the flywheel to separate, due to the thicker friction surface area the flywheel will absorb and distribute excess heat better, the flywheel can be resurfaced, and it is lighter. All of these translate to a longer life and better performance as well as you only need to buy the flywheel once. The JMTC flywheel will save you money since you only have to buy one, last longer, reduce the chance of glazing the clutch and wont catastrophically fail. This flywheel is street, track, and strip ready so there is no reason you cant get one today, the real question is are you ready for the piece of mind it will bring!
