Description

Rennsport Factory bespoke billet flywheel conversion

  • Bespoke billet single or dual to single mass conversion flywheel for most Mercedes models
  • Forged chromoly steel flywheel
  • Usually lightened to around 7KG. OEM and diesel weights available.
  • Dynamically balanced
  • Various diameter road and fast road clutch options
  • M102, M103, M104, M111, M112, M113, M113k, M117, M119 OEM and 60-2 timing markers available

 

Rennsport Factory’s single and dual to lightened single mass flywheel conversion kit is available for nearly any Mercedes engine and gearbox combination. The flywheel is CNC machined from a billet of chromoly steel bespoke to each order. These are dynamically balanced and as the timing and starter gear are machined into the flywheel the end product doesn’t require any bolts or ring gears pressed on to the flywheel. The unit comes all one piece for optimum high rpm safety. Our lightened units allow the engine to rev and respond faster when compared to OEM.

The single mass gearboxes were generally in cars up to around 1990, there after most will need our dual to single mass conversion. This is the unit needed to convert any older Mercedes to the later 716 6 speed gearboxes from slightly more modern cars as an example. A small example gearbox list can be found at the bottom of the page. Any doubts please send us your car details and we can confirm fitment.

The flywheel is available with M102, M103, M104, M111, M112, M113, M117 and M119 timing markers for early 2/3/4 prong and the later 60-2. All timing markers are left in the OEM position where possible. Each flywheel will weigh in at around 6.5-7kg and is machined to order, due to this, for an we can customise or make the flywheel to almost any specification required. If there is an engine not on our list, please contact us, we’d be interested to develop it.

The issue with converting from a dual mass to single mass flywheel is the OEM dual mass setup is designed to offer a vibration damping function in the flywheel rather than the friction disc like the older single mass setups. The clutches available for most dual mass gearboxes come with a solid hub friction which when combined with a single mass flywheel lose the damping function which makes for an easier drive and helps prolong the life of the gearbox.

Each of our clutch systems are made bespoke to our specification retaining the damping function of a friction disc from a single mass clutch set without any sacrifice in performance or longevity in the clutch or gearbox but carefully rated for the torque we have specified. We’ve seen many cheaper units prematurely fail due to the springs not being up to the stated specified torque, once compressed the hub rides on the rivets and the clutch acts as a solid unsprung unit which as it isn’t designed for this cannot hold the torque for long. For this reason, we only offer our dual to single mass flywheels as a kit with a properly specified clutch.

 

Clutch choice

To get the best from any clutch system, it needs to be specified correctly for its application and within the torque rating.  We have 3 categories, road, fast road, and light competition clutches. Full competition clutches are found on another listing. A smaller or lighter clutch will have a lower inertia and will therefore respond faster.

If you occasionally drive hard on the road or the car sees the odd track day we’d recommend stepping over to our fast road clutch system. This system retains a heavy duty organic or kevlar lining, both of which are less agressive on the transmission and retains a lighter engagement when compared to the cerametallic linings found in the light and full competition clutches. Our Kelvar lining will be slightly more aggressive but will hold more heat when compared to the organic.

If your vehicle is mainly a track or drift car, but you still drive it on the road occasionally, we’d recommend our light competition system. This system includes a 6 paddle clutch with cerametallic lining. 4 and 8 paddle are available on request. This lining will engage quicker and is considered better to drive hard with the main advantage being it will withstand the extra thermal input of track and competition use prolonging the life of the clutch in these situations. The downside is the quicker engagement and response can be considered more aggressive and could take some getting used to in normal road situations.

The unsprung hub options may have increased judder and is only recommended if the sprung hubs cannot withstand the torque you require.

Some of the commonly sold flywheels are in stock, but due to the large range we offer the kit is usually made bespoke to order and will be 4-8 weeks to get it through the machine shop. Please send us an email if you need an ETA before ordering.

 

Note for the cars with the M117 or M119 engines, these have a different bell housing pattern to the standard pattern found on most other earlier models, be aware there isn’t a standard combination to suit these engines and a Mercedes gearbox without adaptation. If you select these timing markers with this flywheel we assume you’ve made your adapter plate to suit the offset you chose at ordering.
