Rear Body Post Precision for T4 Cars

For RC hobbyists focused on fine setup, the XRAY 301390 Graphite Shim set delivers a dependable way to move and secure rear body posts. Made from 3.0mm graphite, the shims sit flush in the T4 Series chassis to reduce flex and boost consistency lap after lap.

Tweak Aerodynamics with BPA Positions

These CNC-machined graphite parts integrate with the Body Position Adjustment (BPA) system to let you choose between three rear body post positions. Small changes in post location help tune airflow and rear-end balance for more predictable handling on varying track surfaces.

Engineered for Easy Fitment

Designed specifically for XRAY T4 Series cars, including T4F variants, the shims are simple to install and remove during setup changes. Whether refining corner entry or mid-corner stability, these shims are a practical upgrade for precise chassis setup.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will these shims work on non XRAY rear posts?

They are made for the XRAY T4 Series geometry. Some other cars with identical post spacing may accept them, but always check measurements before assuming fitment.

How do I pick which of the three positions to use?

Start with the middle position and test handling changes one step at a time. Use small track tests to judge rear grip and stability before committing to a new position.

Are the graphite shims durable for repeated use?

CNC-machined graphite is robust but can be brittle under extreme force. Handle with care during installation and avoid over-tightening mounting hardware.
