This accessory is an RC-scale caster pointer adapter created to check caster angles accurately on XRAY X20 and X23 chassis. It is intended to interface with the 4D setup system and provide repeatable reference points for measurement and adjustment tasks.
The set includes two adapters and is engineered to line up with the chassis' existing setup fixtures so pointer placement remains consistent between sessions. It is useful when you want to compare left and right caster readings or capture a baseline before more detailed suspension tuning.
To install, place the adapter on the setup plate or designated locating points, secure it with the original screws, then attach the caster pointer as your 4D tooling requires. Check for any potential contact with servo linkages or suspension components before final tightening.
A practical setup aid for touring car enthusiasts, this adapter stabilizes pointer positioning for dependable caster checks and iterative adjustments.
