The XRAY 372327 X1 Aluminum Caster Bushing Set provides a simple way to vary caster angles across a 6 to 9 degree range, helping you tune front-end bite and recovery. Built from reliable aluminium, these bushings support repeatable setup changes on different track surfaces.
Aluminium combines strength and low mass, giving a precise pivot point that resists deformation during hard braking and cornering. The XRAY 372327 package includes three bushings so you can fit the parts needed for testing and race day.
Raising caster generally improves stability and return to centre, while reducing it can loosen turn-in. Use the 6-9 degree choices to fine-tune steering balance to tyre compound and circuit grip.
