Aluminum Backbone.

The most significant change to the latest RX8 platform is the all-new aluminum backbone. The main frame and backbone of the car consist of high-precision aluminum bulkheads and aluminum suspension holders that are mounted to the aluminum chassis.

All bulkhead parts are CNC-machined from premium Swiss 7075 T6 aluminum and have been designed to provide the lightest and strongest possible support framework for the car with maximum flex characteristics for increased traction.

The bulkheads are anodized in a distinctive orange color. XRAY’s legendary attention to detail is noticeable in all the precisely chamfered edges. (Color may vary slightly between products.)


The RX8 chassis has been re-designed to accommodate the new aluminum bulkheads and suspension holders. The chassis has enhanced performance in the corners and provides great stability.

Overall, the chassis is very narrow to increase chassis flex and generate more traction and steering. The narrow chassis also prevents chassis contact in corners and helps to eliminate the feel of the car ‘stopping‘ in mid-corner.

The lightweight chassis is CNC-machined from 5mm premium Swiss 7075 T6 aluminum and is strategically machined in low-stress areas to make it as light as possible without affecting strength or rigidity.


The chassis has strategic cut outs for optimized flex characteristics. The holes for the engine mounts are now centric and closer together for improved flex.

The chassis features cut outs for all bulkheads, front lower arm mounts, radio plate mounts, and front shaft holder as well as rear layshaft bulkheads for perfect fitment and to ensure that all parts will always mount into the same position.

The outer edges of the chassis have been beveled and screw holes have been countersunk to provide a smooth lower surface.


One of the most significant changes to the latest RX8 platform is the all-new aluminum bulkheads. With changing rules moving to larger, harder tires, the traditional composite bulkheads were changed for aluminum. The new aluminum bulkheads provide improved stiffness & flex characteristics for better steering characteristics, even with hard spec tires.

The super-lightweight Swiss 7075 T6 aluminum bulkheads have a very clean and lightweight design to give the lowest weight and CG, making the RX8 easy to service while still giving easy access to all parts.

2-Speed Bulkheads.

All-new aluminum rear 2-speed shaft bulkheads are separated from the rear bulkheads to give proper flex which translates into maximum traction. All ball-bearings are installed in composite bushings to eliminate transfer of vibrations from the engine.

The bulkheads are CNC-machined from premium Swiss 7075 T6 aluminum to ensure the lightest & strongest support framework.

Rear Upper Clamps.

The all-new rear upper clamps were re-designed to fit the new aluminum bulkheads. The rear Swiss 7075 T6 aluminum upper clamps hold the rear shock tower and the graphite upper arm holders.

Front Upper Clamps.

The all-new front upper clamps were re-designed to fit the new aluminum bulkheads. The front Swiss 7075 T6 aluminum super-lightweight upper clamps hold the front shock tower and the front upper arm mount and make the access to the front one-way super easy.

Front Upper Arm Holders.

The all-new front upper arm holders were designed to work with the new aluminum bulkheads. Each upper front arm holder is mounted to the front upper clamp via a single screw and to the radio plate with two screws. This way, the front suspension has optimized flex for improved in-corner steering and better steering response. One of the 2 mounting screws of the radio plate may be removed for even more flex – as part of the Multi-Flex™ system.

The Swiss 7075 T6 aluminum front upper arm holders were designed to allow the upper arms to be moved more rearward for increased caster angle and improved cornering speed.

Front Middle Shaft Holder.

The aluminum front middle shaft holder was re-designed to work with the new aluminum bulkheads. The holder works now as a belt tensioner for the front & side belts. CNC machined from premium Swiss 7075 T6 aluminum, the smart design also allows for quick & easy front belt changes.

Radio Plate.

The new radio plate was re-designed to work with the new aluminum bulkheads, new fuel tank, and new steering servo mounting system.

The radio plate is CNC-machined from 2.5mm graphite material and the design allows for easy removal of the entire radio plate (with all electronics) for quick & easy servicing and cleaning.

Radio Plate Multi-Flex™.

The flex of the radio plate can be now adjusted independently from the chassis flex, giving more fine tuning options. Using the bushings in the rear, the radio plate can be mounted to the mounts with either fixed position or with flex. The fixed setting is recommended for high-traction conditions, while the flex setting is recommended for low-traction tracks

A brand new and very useful new feature is the front Multi-Flex™ adjustment via radio plate bushing in the servo saver area. When the bushing is used, the setting has a fixed position; when the bushing is removed, the screw is directly mounted on the servo saver post and the whole front suspension has increased flex. The fixed setting is recommended when there is sufficient in-corner steering, while the flex setting is recommended for increased in-corner steering.

Radio Plate Mounts.

All-new radio plate mounts were re-designed to fit into the new aluminum frame. Made from Swiss 7075 T6 aluminum, these lightweight mounts give improved flex characteristics and durability.

Muffler Mounting.

The muffler mounting system was re-designed and moved from the alu front middle shaft holderto the front left bulkhead to allow alu front middle shaft holder to adjust the belt tension of the front and side belts.

Fuel Tank.

All new narrower fuel tank allows for improved fuel movement for more stable & consistent engine operation mainly at lower fuel levels.

The 125cc fuel tank with hypertonic tank lid and internal stone-type filter is positioned in the center of the car and sits as low as possible. The internal baffles inside the fuel tank ensure that the fuel will always be in the area around the fuel line intake so even in long, fast corners the fuel will be constantly supplied to the engine.

Fuel Tank Mounting.

The new fuel tank mounting has been re-designed with the fuel tank being mounted atop the radio plate for easier insertion & removal from the car. Cleaning and maintenance around the fuel tank and radio plate is now much easier. The fuel tank is mounted on aluminum fuel tank posts with rubber grommets and secured by micro clips.

The receiver battery pack is located beneath the fuel tank help create the lowest CG possible.

The front arms were extended to work with the new front suspension geometry, and the position of the front wire anti-roll bar was re-designed as well.

Suspension arms are one of the most important parts of any RC model car, as they directly influence the handling and racing characteristics of the car. The RX8 suspension arms are the result of long-term testing of different designs and layouts. Length, thickness, flexibility, geometry of suspension points and materials used… these are all the concepts and details that had to be thoroughly reviewed to create optimal suspension arms.

The exclusive composite mixture used for suspension arms is a perfect balance between reliability and performance. The suspension arm itself is rigid enough to provide a responsive feel, yet soft enough to provide extreme durability.

Steering Blocks Extensions.

The steering block extensions were re-designed for new Ackermann geometry and improved steering characteristics. The extension is mounted to the steering block, and features 3 different Ackermann positions. The kit includes 2mm bump steer shims for improved bump steer characteristics; bump steer can be easily changed by adding or removing shims.
