Chassis.
The chassis is CNC-machined from 3mm high-quality Swiss 7075 T6 aluminum, strategically machined in low-stress areas, and then anodized to make it as light as possible without affecting strength or rigidity. 

Non-essential material below the engine, fuel tank, and differential was removed to allow for the lowest possible center of gravity and appropriate chassis flex.

Side Guards.
The strong side guards incorporate a large bottom radius to have maximum best flex performance. The side guards are moulded from a specific composite mixture for increased flex that helps to generate more traction.

The tough composite side guards protect the car, muffler, and fuel tank from side impacts. The side guards perfectly fit the chassis and seal against dust.

Chassis Braces.
Front and rear chassis braces have significant influence on chassis stiffness and flex, and as such have great impact on handling under different grip conditions. 

The front chassis brace have two options, short for more traction and longer for more stability. 

The longer rear is moulded from a medium-stiff composite mixture for proper flex & rigidity, and allows the mounting of optional graphite inserts to reinforce the chassis brace to make it even stiffer (suitable for high-traction conditions).

Suspension.
Correct suspension geometry is one of the most important features of any RC model car, while at the same time being one of the most difficult & challenging features for a designer.

Suspension is always a mixture of:
• Design and shape of individual suspension parts
• Flex and hardness
• Materials used
• Mounting system
• Geometry and position of mounting points of connecting parts

From the suspension arms, through the suspension blocks, to the robust steering blocks, every suspension part has been carefully designed for the 1/8 racing platform to provide responsive racing characteristics in all conditions.

Suspension Arms.
GTX8 suspension arms are the result of long-term testing of different designs and layouts. Length, thickness, flexibility, geometry, and materials used… these are all part of the concepts and details that are thoroughly reviewed to create optimum suspension arms.

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

Steering Blocks.
XPBS™ steering blocks are unique, innovative, smart... an authentic XRAY innovation. 


The steering blocks feature the following integrated geometry adjustments:

• camber
• caster
• bump steer
• track-width
• kingpin


The steering block consists of a super-lightweight composite steering block and stiff Swiss 7075 T6 kingpin plate. The steering block is mounted via massive pivot balls into the upper & lower arms. 

The upper pivot ball is mounted into an adjustable upper ball joint and via roll center shims to the kingpin plate; this assembly allows camber and upper roll center adjustment. Using shims of various thicknesses, the upper roll center can be adjusted quickly & easily. 

The lower pivot ball is mounted into the steering block via an adjustable alu nut and composite bushing. By adjusting the pivot ball, both track-width and camber can be adjusted. 

A higher roll center (more shims) is recommended for grippy, high-traction tracks as well as for bumpy tracks. 

A lower roll center (fewer shims) is recommended for slippery and smooth tracks.

The included kingpin plate has two different mount possibilities to choose from 0° or 7 degrees°.
