For racers seeking precise handling changes on the XRAY X4 2025, the XRAY 962045 4x5x0.2mm washer set is a straightforward tuning aid. These steel washers slip beneath the top deck flex screws to alter deck stiffness, letting you fine tune flex for different track conditions. Fit them to the front or rear top decks to balance grip and turn in during practice and race sessions.
The XRAY 962045 washers are made to broaden your tuning options on the X4 2025. Modifying top deck flex affects mid corner balance and steering feel, which helps you match the car to asphalt, carpet, or mixed surfaces encountered at club tracks.
Install the washers evenly across the top deck screws to keep the chassis balanced. Test changes one step at a time so you can judge how each washer alters handling. Use them only on the front or rear when you want asymmetric flex adjustments.
