The RX8 platform shares the majority of its parts between the nitro and electric versions.

The new chassis and narrowed front suspension holders help to increase stability & traction. The chassis features more cutouts for improved flex characteristics and additional cutouts that increase airflow for better motor cooling. The extra-large cutout under the servo and radio box allows super low mounting to reduce the CG.

All-new chassis and the narrowed front suspension holders help to increase stability & traction. The chassis features more cutouts for improved flex characteristics and additional cutouts that increase airflow for better motor cooling. The extra-large cutout under servo and radio box allows for very low placement of those components to reduce the CG.

The chassis has cut-outs for the bulkheads, arm mounts, radio plate mounts, and front layshaft holder for perfect fitment to ensure these parts will always mount into the same precise position.

The outer edges of the chassis are beveled and screw holes are countersunk to provide a smooth lower surface with maximum clearance during cornering.

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

The lowered bulkheads create clearance to lower the radio tray and the new design integrates the upper shock mount position to eliminate the need for a separate shock tower. The bulkheads also incorporate a flex adjustment for the front suspension using the included cross brace. The rear aluminum bulkheads have a 2mm wheelbase adjustment for the lower and upper arms for easy traction tuning.

The bulkheads also incorporate a flex adjustment for the front suspension using the included cross brace. The rear aluminum bulkheads have a 2mm wheelbase adjustment for the lower and upper arms for easy traction tuning.

The aluminum bulkheads provide optimal stiffness & flex characteristics for better steering characteristics, even when using hard spec tires.

All bulkheads are CNC-machined from premium Swiss 7075 T6 aluminum to provide the lightest & strongest framework for the car.

The lower profile of the front bulkheads allows the radio tray to sit lower for improved CG. The upper shock mount position is also integrated into the bulkhead eliminating the need for a separate shock tower and creates an additional flex adjustment for the front suspension using included cross brace. The innovative front upper shock mounting system installs the front shocks directly to the upper clamps using shims for setup adjustments.

The chassis flex on the RX8 is adjusted in front to control traction and responsiveness, while the center and rear of the car have optimized fixed flex settings for the best overall balance. The front chassis flex is adjusted in 4 different areas:

• Front upper brace
• Front Multi-Flex plate
• Front upper arm holders
• Front lower chassis brace

The new front upper bulkhead brace is used for easy flex adjustments. The car has more stability with the brace installed and it will create more traction and steering when the brace is removed.

The redesigned lightweight front upper arm holder features an additional flex setting by connecting the holder to the front bulkhead from the side to reinforce the assembly. The upper arm holders use the smaller eccentric bushings and spacing shims from the NT1 for a more compact design to create the space to lower the radio tray height and reduce the overall CG.

Redesigned graphite rear upper arm holders provide more clearance above the rear belt. The rear upper arm holders are machined from strong 3.5mm graphite material for optimal flex of the rear suspension. Both front & rear plates are mounted on the rear upper clamps to capture the upper pivot pins.

The receiver box was completely redesigned. The new lightweight shape is ultra-compact and can be positioned as low as possible and closer to the chassis centerline for better weight distribution.

The redesigned servo saver has a shorter stand to match the lowered radio tray position and a key-lock system that ensures the servo saver will stay secured even during chassis flex in extreme conditions.

The centralized servo saver is ball-raced for super-precise and smooth operation, with an adjustable spring collar for fine tuning of the preload. The servo saver also features easily adjustable Ackermann positions that greatly influence the steering characteristics, allowing the RX8 to be tuned for all driving styles and track conditions.

The updated rear transmission features simplified aluminum holders that eliminate unnecessary braces to increase chassis flexibility in key areas while their wider positioning provides improved support for the speed shaft. To increase transmission reliability, the speed shaft adapter for the rear belt pulley now uses longer pins. The one-way carrier has a new lightweight design for reduced rotating mass. The transmission parts are installed on a precision-manufactured, super-smooth hollow middle layshaft made from tough HUDY shaft steel that is additionally heat treated for extra strength and long life.

Thanks to the new compact receiver box, the radio tray layout has space to move the servo lower with the receiver box located in the middle. The steering servo holders are also redesigned
The rear tray holders are super lightweight and reinforced in critical areas to eliminate breakage. The new compact receiver box allowed the reconfiguration of the radio tray layout moving the electronics closer to chassis centerline.
