Factory Pro FP-O-XCP014 Xray X4 Bulkhead Upper Mount Plate Set - Precision Shim Pair 1mm/2mm  [FP-O-XCP014]

Adjust Chassis Flex for Corner Control

The Factory Pro FP-O-XCP014 Xray X4 Bulkhead Upper Mount Plate Set lets you experiment with chassis flex to dial in turn-in and rotation. Including both 1mm and 2mm plates makes it easy to compare small but meaningful changes to on-track behaviour.

Simple Changes, Noticeable Effects

Swapping between plates affects how the front end reacts under load; the 1mm plate promotes a livelier, more forgiving feel while the 2mm option tightens response for sharper exits. Fitment is straightforward and repeatable on the Xray X4 platform.

Precision Fit and Durable Construction

These plates are produced to precise tolerances so they sit securely in the bulkhead area, giving consistent results session to session. They hold up well under race use and frequent setup trials.
