The XRAY 352289 Composite C-Hub sets a 6-degree caster specifically for GT on-road competition. After comparative testing of several caster angles, this version provided the best compromise between steering precision and tyre longevity. It fits GTX and GTXE models, making it a direct upgrade for drivers seeking dependable handling over a race distance.
The 6-degree layout improves steering feel versus the prior 16-degree arrangement, giving drivers clearer response at the wheel. That helps when negotiating successive corners at race pace.
With reduced lateral aggression on the tyre shoulder, the 6-degree caster slows wear progression so your tyres retain grip longer into an event. This helps maintain more uniform lap times as the race continues.
