Some information shown below may include details from previous kits, and it may vary slightly from current kit specifications.
Front C-hubs were specially developed for the GT on-road platform. After extensive tests of various caster angles, the final 6° caster block was selected as the best choice to work in the wide range of racing conditions found at GT events.
The C-hub geometry significantly improves steering characteristics over the previous 16° hubs. The reduced caster angle also helps to reduce tire wear, creating more consistent handling during longer main events.
The steering blocks feature steering Ackermann plates that improve corner entry steering by increasing the outside wheel angle. Machined from graphite, the plates are easy to mount to the steering blocks for replacement or adjustment.
The shorter front and rear upper camber links match the rear hub graphite camber extensions and front and rear inner camber link positions to make the car more reactive in front and provide more rotation from the rear suspension.
The servo saver features conical spring that is longer and stronger. The spring ensures more precise steering and improved reliability.
The servo saver posts feature locking system that keys into the chassis plate to ensure the servo saver setting will not change while running.
To improve servo saver reliability (especially in dusty conditions), it is moulded from a graphite material that is more resistant and efficient in dusty conditions. The dual-arm steering system is simple yet effective, featuring an integrated easily adjustable servo saver, and a Swiss 7075 T6 aluminum steering plate.
Ackermann is easily adjusted by changing steering link mounting positions on the steering plate. Bump steer is adjusted by inserting shims between the steering plate and steering linkage.
Both front and rear suspension arms are now softer than the previous GTX kits. In comparison to the extra-hard suspension arms included in previous GTX kits, the latest GTX features Medium front and Hard rear suspension arms. This combination of arms helps to increase traction in every track conditions.
The braking cams have an updated profile to improve the braking efficiency. The cams apply pressure to the brake backing plates more evenly in the center, improving braking feel and extending the service life of the brake pads.
To further improve the braking efficiency and to ensure consistent braking characteristics, the ultra-efficient pre-glued brake pads are included in each GTX kit.
The laser-cut, precision flat-ground steel brake disk provide fade-free braking in conjunction with the include brake pads. The brake disk is small, slim, and very lightweight. The precision hand-grinding allows true, wobble-free rotation. Both brake disk and brake pads are specially heat-treated for maximum lifespan.
