Carbon rear upper clamp tailored for X4F use

This rear upper clamp is crafted to cut unsprung weight at the rear and shift effective mass forward, so drivers can influence handling characteristics. The clamp combines the rear body post mount into one carbon component, preserving a compact footprint while still allowing flex bulkhead adjustments.

CNC-machined from high-grade carbon fiber, the clamp delivers precise dimensions for consistent setup changes. It is supplied as a set of two pieces and fits applications that call for the X4F rear upper clamp.

Tuning note: the lighter carbon clamp typically reduces rear-end inertia and moves balance forward. Use this effect alongside suspension and flex tuning to adjust rear grip, rotation, and mid-corner response on touring car layouts.

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 this change my car's rotation?

Yes. By lowering rear mass and shifting weight forward, the clamp can increase rotation through mid-corner. Combine with spring, damper, and flex adjustments to achieve the desired balance.

Does the part include the body post mount?

The rear body post holder is integrated into the clamp design, so a separate post bracket is not required when installed correctly.

How many items come in the pack?

The product ships as a set of two carbon clamp pieces intended for the rear assembly.

Do I need special tools to fit this clamp?

Installation uses standard fasteners; basic RC hand tools are sufficient. Verify alignment and torque settings, then re-check body clearance and suspension operation.
