If you want crisper turn-in and better traction on slick or medium-grip surfaces, the XRAY 305357 Aluminum Wheel Hub Offset -0.5mm is a straightforward upgrade. By shifting each wheel 0.5mm inward, these hubs narrow the track to help the X4 bite better in corners.
Using a -0.5mm offset tightens the stance slightly, which often translates to improved front grip and steadier mid-corner behaviour under lower traction. Drivers can use these hubs as part of a balanced setup change to suit track conditions.
