Chassis.

The new chassis is updated for the narrowed rear suspension configuration. The rear bulkheads are mounted 8.4mm closer together. The rear arm mounts move the inner pivot pins 2.5mm closer together, which combined with the bulkhead placement generates more rear traction and improves the stability of the car.

The chassis also features a unique, innovative front flex adjustment using a removable aluminum brace.

The chassis is narrower to increase chassis flex and generate more traction and steering. The narrower chassis also prevents chassis rub during cornering to help eliminate the feel of the car ‘stopping‘ in mid-corner.

Adjustable weight positions on both sides of the chassis offer quick & easy weight balance adjustment.

Chassis.

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

The outer edges of the chassis have been beveled and screw holes have been 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.

Bulkheads.

The aluminum bulkheads provide optimal 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, and still allow quick access to the driveline components for reduced maintenance downtime.

Rear Bulkheads.

All-new rear bulkheads have been redesigned to fit the new composite anti roll bar bearing bushings that eliminate the wear of the bulkhead. The rear bulkheads are an integral part of the rear suspension Multi-Flex™ system that offers the choice of different flex adjustments.

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

Front Bulkheads.

All-new front bulkheads have been redesigned to fit the new composite anti roll bar bearing bushings that eliminate the wear of the bulkhead.

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

Suspension Mounts.

The all-new redesigned rear lower suspension mounts move the rear lower arms 2.5mm closer together for improved traction and stability.

The front & rear lower suspension holders are fully independent from the bulkheads, mounting directly to the chassis to increase traction and make the car easier to drive.

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

Suspension Extensions.

All-new rear suspension extensions update the shock mounting positions to match the new rear suspension pivot pin and arm locations. Both front & rear extensions are made from laser-cut steel and additionally black coated for improved durability, and they also features optimized shock mounting positions.

Rear Upper Arm Holders.

All-new graphite upper arm holders feature new positions for the eccentric bushings that position the upper pins 2.5mm narrower to work with the new rear lower arm mount position.

The rear upper arm holders are machined from strong 3.5mm graphite material for optimal flex of the rear suspension. Both front & rear mounts are mounted on the rear upper clamps.

Shock Towers.

The rear shock tower was redesigned to work with the new rear narrower bulkheads mounting and updated suspension geometry.

Both front & rear shock towers have optimized shock mounting positions.The towers are made from thick 3mm graphite material for maximum durability.

Front Wire Anti-roll Bars.

All-new front wire anti-roll bar was redesigned to work with the new adjustable system that allows easier adjustment of the bar as well as remove any excess play from the system.

The RX8 includes both wire & blade-style front anti-roll bars for freedom of choice based on track conditions.

The wire anti-roll bar is used to increase steering response on small, technical tracks. The wire anti-roll bar is mounted to the bulkheads from the outside to allow quick & easy changes and adjustment. The wire roll bar turns in ball-bearings for maximum precision and freedom of movement. Anti-roll bar height can be quickly & easily adjusted.

Rear Anti-roll Bars.

All-new rear wire anti-roll bar was redesigned to work with the new adjustable system which allows easier adjustment of the bar and reduce play.

The rear 2.8mm anti-roll bar helps to reduce rear chassis roll. The roll bar turns in ball-bearings for maximum precision and freedom of movement. For fine precision tuning, optional wires of different thickness are available. Anti-roll bar height is adjustable via a screw… quick & easy.

Axles & Outdrives.

The all new rear solid axle shaft and lightweight composite pulley were redesigned to fit the new narrow positions of the rear bulkheads. All outdrives are manufactured from HUDY Spring Steel™ and are specially ground for maximum precision. All pulleys have self-cleaning holes to reduce buildup.

The front 1-way and rear solid axle are small and light, ensuring super-low rotating mass and lowest CG. The super-lightweight front 1-way bearing is inserted directly in the axle, and the axle body is machined from Swiss 7075 T6 aluminum.

Pivot Balls.

The all-new rear pivot balls were lengthened to work with the new lower rear arm mounts to still achieve the desired vehicle width.

The RX8 pivot ball suspension contains precision pivot balls that are specially hardened to better withstand harsh crashes and extend their lifespan. A total of eight (8) pivot balls are included and are captured by strong M10 composite nuts to minimize weight and give smooth suspension movement.

Standard pivot balls are made from steel for maximum durability and lifespan. For those who are focused on minimizing unsprung weight, optional lightweight aluminum and titanium pivot balls are available.
