The XRAY 352289 C-hub uses a 6-degree caster angle optimised for GT on-road performance. After evaluating several caster settings, this angle proved best for steady handling and reduced tyre wear in race conditions. It is compatible with GTX and GTXE chassis, offering a straightforward upgrade for drivers wanting more consistent steering through a full race distance.
The 6-degree geometry sharpens steering compared to the older 16-degree layout, giving drivers crisper turn-in and better mid-corner control. That clarity is useful when running aggressive lines at speed.
Reduced lateral scrub from this caster setting helps tyres keep more of their working surface during long runs. The result is more consistent lap times as tyre performance drops off less rapidly.
