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.

Chassis Braces
Front and rear chassis braces have significant influence on chassis stiffness and flex, and as such have a great impact on handling under different grip conditions. The longer rear brace is moulded from a medium-stiff composite mixture for proper flex & rigidity, and allows the mounting of optional graphite inserts to reinforce the brace to make it even stiffer (suitable for high-traction conditions).

Weight Balance Adjustment
Weight balance on the GTX8 is easy to adjust for different track conditions. Weight can be moved to the front, middle, or rear by moving the suspension arms as required to get the best handling.

XRAY Pivot Ball Suspension XPBS is a uniquely innovative concept, and smart R&D design. The ultra-robust pivot ball suspension has integrated suspension geometry adjustment, with different kingpin plates being optionally available.

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 to design properly. 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.

I.S.S. Suspension Holders
The aluminum suspension holders feature Integrated Suspension Settings (I.S.S.) which allow for quick & easy suspension geometry setting. Using eccentric suspension bushings inserted into aluminum suspension holders – as well as additional suspension shims – the GTX8 suspension geometry can be completely adjusted in mere seconds.

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.
