XRAY 301390 Graphite Rear Body Post Shim Set (3.0mm, 4pcs) Precision Tuner  [XR-301390]

Set Up Rear Body Posts Precisely

RC enthusiasts aiming for consistent body mounting will value the XRAY 301390 Graphite Shim set for controlling rear post placement. Each 3.0mm graphite shim is precision cut to give stable seating in the T4 Series chassis, helping reduce body movement under load.

Use with the BPA System

These CNC-machined shims form part of the Body Position Adjustment setup, offering three selectable positions for the rear body posts. That adjustability helps you optimise rear downforce and tuning range for different track conditions.

Installation and Compatibility

Built with the XRAY T4 Series in mind, including T4F models, the shims install without modifications and support repeatable setup changes. They are suitable for racers and tuners looking for small but effective setup gains.
