CentraFlex V2 2.0mm Carbon Topdeck for Mugen MTC2

Building on our range of Carbon Fibre Flex Options, we are excited to introduce our next evolution in Flex Technology, our CentraFlex V2 2.0mm Topdeck for the Mugen MTC2!

Improvements made in our V2 Topdeck

  • Custom designed 3.5mm diameter topdeck motor-mount screws (RCM-TMS). This increases the material in the topdeck over 6mm cutouts for bearings, making the flex characteristics of the topdeck more consistent and efficient, also strengthening the topdeck at the same time due to more material.
  • More subtle flex options are now available thanks to the reduction in pivot screw size.
  • More bridges at the front of the topdeck which can be cut depending on desired flex characteristics to suit your high or low traction track. 
  • The topdeck has been able to be further narrowed around the pinion area without compromising strength to allow all pinion sizes and gear ratios to be catered for.


  • Centrally distributed flex with several options to move flex point
  • Easy overall flex tuning without requiring removal of topdeck to bulkhead mounting screws 
  • Easy removal of spur gear
  • Increased clearance to pinion gear enabling you to use all sizes and combinations without restriction
  • Designed and tested in several platforms with great success
  • Designed and manufactured in Australia 

A single sided topdeck design provides a brilliant option in moving our technology forward. Conventionally in Mid Motor setups, the front of the topdeck is entirely split, just like on the MTC2, in order to be able to slide the topdeck over the front belt. This provides a significant amount of flex to the front of the car only, creating quite an imbalance in the topdecks flex characteristics.

The CentraFlex has been developed to slide in from the side under the belts, and due to the single sided design, can be joined in front of the spur gear to prevent excessive front topdeck and bulkhead flex, bringing back the balance of front to rear flex provided by the topdeck. In doing this, we have significantly increased the clearance to Pinion Gear, making you now able to run any combination you can think of! This design also makes it very easy to change the spur gear.

By installing or removing the 3.5mm Topdeck Motormount Screws either side of the spur gear, we can change the flex point of the car instantly, either moving it forwards or backwards to adjust the balance of the car. 

As well as this tuning option, we also have braces which can be cut on the topdeck to even further alter the flex characteristics, by changing the flex between the bulkheads, and also moving the flex closer to the bulkheads.

This provides a lot of option in not only adjusting the flex point of the car, but also the overall flex. Combined with the options provided under the chassis by the motor-mount, it can be a very powerful tuning option in getting the absolute most out of your car. 

The best part - all of this translates on the track! All of our testing so far by ourselves and our team drivers has proven this topdeck design to be the pick of the bunch. It offers an incredibly smooth driving feeling, coupled with increased mid-exit corner and high speed steering over the original topdeck. It is very adaptable to all different kinds of tracks, with the inserting and removal of bearings, and also cutting braces making substantial differences in the feeling and balance of the car.

Initially an asymmetrical design would have been thought not to provide symmetrical flex, but in fact the flex is incredibly balanced. To test the theory we even made a "flippable" topdeck and tried brace left and brace right configurations to see if we could feel the difference. It felt 100% identical with laptime reflecting this. That's how we knew that this was going to be the way forward!

We strongly believe this layout proves an advancement in the flex technology of Mid Motor cars and hope that you will have the same experience with your CentraFlex Topdeck for your MTC2! 

Available in both 1.6mm and 2mm versions. We suggest 1.6mm for use with Aluminium Chassis, and 2mm with Carbon Chassis.
