Xray X4 aluminium caster bushings
For their X4 platform, Xray have introduced 2 new optional aluminium caster bushings. Together with the kit standard version, these new items allow for 3 different caster settings on both the front and rear of the car. Quick and easy to make the adjustment, they have been precisely machined from lightweight aluminium, are easy to recognise with their machined dots, and come in a set of 4 pieces.
