RCM-X4-SFCH
Introducing our SlimFlex HARD Carbon Chassis for the new XRAY X4 22/'23!
The XRAY X4 sports a unique chassis design which is already very low profile. In this case we decided to work on the flex point of the chassis, ensuring we could optimise the flex, and also the rigidity of the chassis.
This particular HARD version chassis features a significantly stiffer weave of carbon, which reduces the flex greatly. The flex of this carbon chassis fills a large void between a standard carbon chassis and an aluminium chassis, making it the optimum choice for med-high traction asphalt, and low-med traction carpet! Often track conditions can cause the need for an "in between" option, where an aluminium chassis is too stiff and makes the car too easy to drive and slower, and a carbon chassis is too aggressive or difficult to drive to be consistent. The stiff carbon chassis is the perfect middle ground!
One major change on the SlimFlex chassis is the removal of the "through" spool and diff cutouts. We have pocketed these only 1mm deep, which provides a more rigid front and rear. This directs the flex back the the centre of the chassis for more consistent handling. The X4 has no shock towers to brace the bulkheads on the front, leading to excessive bulkhead flex, giving more steering but also making the car inconsistent. Thanks to the pocketed cutouts, there is now significant less horizontal flex between the bulkheads, so you can run without braces, or with thinner braces such as our Bulkhead/Topdeck Flex Dampeners and not get as much flex in the bulkheads on the horizontal axis, but maintain the "caster flex" to increase steering. As well as this, the pocketed cutouts also improve aerodynamics by not allowing as much air up into the chassis, which ultimately improves the downforce.
Finally, the chassis profile has been modified to move the overall flex point of the chassis forward. With the XRAY front profile being fairly balanced front and rear, we have narrowed the front as much as possible. This shifts the flex point forward, stiffening the rear of the chassis ultimately resulting in more steering which is almost always required on asphalt!
All of these features combined bring you a chassis which we believe provides more steering and corner speed, whilst keeping the car easy to drive and stable.
Our chassis are precision cut and countersunk on our CNC machine, in house in Australia from high quality 3K 2.2mm carbon.
