Dial In Top Deck Flex on the XRAY X4

If you want more control over your XRAY X4 setup, the M3x5.5 hex screws in Hudy Spring Steel provide a straightforward tuning option. The shoulder on each screw permits a small amount of movement in the top deck, letting you tweak flex behavior without major modifications. Careful placement of these screws changes how the car reacts in corners and during weight transfer.

Tuning Placement for Cornering and Braking

Fitting screws toward the rear of the top deck typically increases rear grip and steadiness under braking, while moving screws forward helps stabilise the chassis during acceleration and deceleration at the cost of a touch of steering feel. These adjustments help manage handling on tighter, more technical layouts.

Durable Hudy Spring Steel Construction

Manufactured from Hudy Spring Steel, these M3x5.5 screws are made to resist wear and keep consistent fitment. That reliability makes them a sensible choice for racers and dedicated hobbyists who make frequent setup changes.
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 will changing top deck screws affect my lap times?

Small tweaks to top deck screw placement can alter turn-in and midcorner balance, which can translate to faster, more predictable laps once you find the right setting for the track.

Are these screws easy to install on the X4?

Yes, they fit into the existing top deck holes and require only basic tools. The shoulder ensures correct seating while allowing the intended micro movement.

Should I swap them for every session?

Not necessarily. Try one or two positions and evaluate handling over a few runs before making further changes; frequent swaps can make consistent setup work harder.
