Refine chassis balance with a carbon rear clamp

The XRAY 301552 X4F Graphite Rear Upper Clamp is designed to move rear mass forward, improving rotation and steering response. CNC-machined from high-quality carbon fiber sourced in the USA, it reduces weight without sacrificing strength, supporting consistent track performance.

Engineered for consistency

Manufactured to tight tolerances, this graphite clamp delivers a reliable fit and repeatable behaviour across setups. Its lightweight profile helps drivers dial in chassis balance more effectively for qualifying and race runs.

For drivers chasing handling precision

This part is aimed at those who prioritise nuanced handling adjustments. By trimming rear weight, the clamp promotes sharper turn-in and more controllable mid-corner transitions, valuable when refining lap times.
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.

How should I test the clamp on the track?

Run a baseline before fitting and then compare handling on consistent laps. Make one setup change at a time and record lap times and driver feedback.

Will this clamp fit the entire X4F range?

It is produced for the XRAY X4F series. Confirm part compatibility with your specific year or variant to ensure correct mounting.

What setup changes pair well with this part?

Drivers often fine-tune rear damping, anti-roll bar stiffness and toe settings to balance the forward bias introduced by the clamp.

Is carbon fibre prone to fatigue in this application?

High-quality carbon fibre is durable, but inspect after impacts. Replace the clamp if you notice any cracking or significant delamination.

Any tips for pairing with other upgrades?

Combine with complementary lightweight parts cautiously and test systematically to maintain predictable handling across different fuel loads and battery weights.
