Fine control of front-end behaviour for X4F cars

This aluminium front chassis brace is an RC-scale accessory designed to alter the flex characteristics of the X4F front chassis area. Mounted across the front suspension section, the brace gives precise control over how the chassis transfers load and reacts to steering inputs without changing other hardware.

Installation supports multiple screw configurations so you can vary how the brace couples to the chassis. Settings range from no connection for maximum forward traction, to full connection for increased steering responsiveness, with intermediate options to balance corner speed, steering feel and overall drivability. Adjustments can be made trackside using standard hex screws and a hex driver to test settings under different traction conditions.

The part is machined from Swiss 7075 T6 aluminium and finished with a black anodize. As a dedicated RC part for the X4F front area, it is intended for tuning responses on various track surfaces, from low-traction outdoor asphalt to high-traction indoor carpet.

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 fit other XRAY models?

This brace is designed for the X4F front chassis area and its mounting pattern; compatibility with other models depends on shared front chassis geometry and should be checked before fitting.

How does it influence mid-corner balance?

By changing front flex, the brace affects weight transfer through the turn. A stiffer front encourages sharper turn-in and can shift balance toward understeer or oversteer depending on rear setup.

Any tips for combining with anti-roll bars?

When stiffening the front chassis with the brace, you may need to soften the front anti-roll bar or adjust the rear to maintain neutral balance; test changes incrementally to avoid masking problems.

Should I expect big lap time changes?

Effects are typically subtle but measurable: improved steering precision and corner speed in many conditions. Use consistent testing to quantify lap time differences from mounting choices.
