What's the aim/benefit of the Willspeed RF2 conversion?

The Willspeed RF2 conversion platform was designed and manufactured by engineers and racers alike for the true ultimate in performance on medium to high traction surfaces. 

The RF2 design focus's on moving the weight bias forwards by utilising a 5 gear transmission - this allows the motor position to be moved further forwards creating a smaller located area of main mass which aids to control weight transfer. 

The billet aluminium tub chassis is the ultimate in chassis design, the centre of gravity is super low, the chassis has no additional guards or stiffeners removing unwanted tweak and is self integrally stiff. The aluminium selected for its natural dampening properties this not only allows for an incredibly agile platform its also super predictable.  

The end result, a platform that not only loves corner speed but it is also dependable and predictable lap after lap making going fast, easy. 

What about all that Aluminium, must be so heavy right?

Not at all, we build race cars and race cars must be kept light! All our products are carefully processed through the CAD and CAM stages, ensuring they are designed in a manor to maintain low weight but retain high strength. 

The RF2 conversion as a ready to race complete car typically weighs in at 1500g with a full size shorty lipo and Schumacher tyres - comparable and more often lighter than the standard car.
