Hobbyists focused on consistent lap times can use the XRAY 302312 Aluminium Caster Bushing pack for the XRAY X4 to fine tune caster geometry and improve handling predictability.
The kit offers a 5 deg front option and rear positions of 2.5 deg or 3.5 deg, enabling setup tweaks to suit different track grip levels and driving techniques.
Aluminium provides stable geometry under load and precise tolerances, helping reduce play in the steering system and prolong component life compared with softer materials.
