Tuned front weight for the X4F chassis

The XRAY 309824 Front Bumper Brass Weight supplies 100g of brass ballast for the X4F front end. CNC-machined for accuracy and finished in black with laser engraving, it is intended to be a durable fitment that changes handling balance.

Improved traction for FWD cars

Installing this weight beneath the front lower bumper increases downforce at the front axle via added mass, helping the front tyres hook up sooner and reducing wandering on corner entry and mid-corner phases.

Precision CNC brass construction

Made from solid brass and machined to close tolerances, the XRAY 309824 offers a predictable weight and secure mounting with the X4F bumper hardware, so you can tune with confidence.
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 much lap time change can I expect?

Lap time gains depend on track layout and driver style; the weight improves front grip which can produce quicker cornering on technical tracks but needs complementary setup changes.

Can this corrode if it gets wet?

The black coating helps protect the brass, but like any metal part it should be cleaned and dried after wet running to prevent surface tarnish.

Is this compatible with aftermarket bumper designs?

It is designed for the X4F lower bumper profile; some aftermarket bumpers may need modification or an adaptor plate to accept the weight.

How should I store the weight when not in use?

Keep it dry and wrapped to avoid contact with moisture or chemicals. Storing in a small parts box will prevent scratches and keep the engraving legible.

Will adding rear weight negate the front weight effect?

Adding rear ballast will change the balance again; use front and rear weights together only after testing to find the handling you want.
