Stiffer Rear End Upgrade for the X4F

The XRAY 302780 Aluminium Rear Bulkhead for the X4F 2025 series is a solid choice for drivers seeking a firmer rear structure and clearer setup feedback. Swiss 7075 T6 aluminium keeps weight under control while improving load tolerance.

Broader ARS Tuning Range

By locating the ARS link higher and in a horizontal orientation, this bulkhead widens the tuning range for rotation. Small ARS changes translate into noticeable differences in corner entry and exit behavior.

Secure Fitment and Lower Centre of Gravity

Centering pins make alignment quick and repeatable, reducing setup variance. The anti-roll bar sits beneath the drive shafts, which helps lower the centre of gravity and makes the car more composed through transitions.

Durable CNC Finish

CNC machined from premium Swiss 7075 T6, this bulkhead is built for track use. The black anodised finish resists scratches and helps the part remain serviceable across many sessions.
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 do small ARS adjustments change handling?

Small ARS moves influence rotation sensitivity and rear grip balance. Tighter settings can stabilise the rear while looser settings promote rotation for tighter turns.

Will this improve durability for heavy use?

The 7075 T6 alloy and CNC finish increase resistance to bending and wear, so it stands up well to frequent track sessions and aggressive driving.

Any tips for keeping the anodise in good condition?

Avoid abrasive cleaners and wipe the part clean after salty or muddy conditions. A light application of aluminium-safe protectant can help maintain the finish.
