Introducing our latest evolution of topdeck for the Xray T4'21! Based off our extremely popular CentraFlex XRAY T4'20 Topdeck which is used by hundreds of racers globally, it builds on our foundations of believing in centrally located flex on touring cars.
Several of the latest Mid Motor cars (Including the T4'21) have entirely split front topdecks. The reason for this is so that they can wrap around the front belt and still be symmetrical. Our testing has shown that this "split" design can cause an imbalance in flex characteristics which was never before an issue on rear motor cars, however on today's Mid Motor cars can cause the car to be inconsistent and nervous, whilst having reduced on power and high speed steering.
Our CentraFlex is joined in-front of the spur gear, providing a much more centralised flex point. We have proven the "single side" design over the spur gear to be a consistent, tweak free solution and in testing found both physically and handling wise, the car was very balanced on left and right corners.
In the '21 design, we have moved the bearing hole to align with the new '21 Motor mount. Also, after an incredible amount of valuable feedback from our team drivers and various racers around the world, we have added an additional flex option in front of the spur gear. This slightly increases the rigidity of the topdeck giving more corner speed and consistency in high traction conditions. If you're driving on low traction conditions and are looking for more steering, then cutting through this brace will give you exactly that.
As well as handling benefits, our CentraFlex brings several fitment benefits:
- Increased clearance between the front face of the motor and the topdeck for when the car is under high flex load
- Increased clearance between the edge of the motor and the topdeck to fit all brands of motors, and all classes and sizes of pinion/spur combinations without any grinding of topdeck or motor
- Easier installation and removal
- More durable design around the motor (a weak point of the standard chassis)
- Adjustable Front Flex characteristics being able to cut through the braced section
The CentraFlex topdeck is available in 2mm and 1.6mm thicknesses. Refer to the reference guide in the photos to see what most suits your conditions!
We also recommend using this topdeck with our SlimFlex 2.2mm Carbon Chassis for XRAY T4'21 here! The flex characteristics of the chassis are designed to compliment the chassis.
