The XRAY 306198 battery holder for the T4'19 chassis provides a simple way to control battery position for handling refinement. Combining graphite construction with an optional brass weight lets drivers tune mass distribution with confidence.
The unit allows movement of the battery in both front/rear and left/right axes, offering a 4mm front/rear adjustment. The brass insert contributes an extra 7.5g, enabling fine ballast changes on the battery side of the car.
As the holder secures battery tape on the top only, it removes the need for under-chassis tape. That choice increases chassis flexibility and can reduce ride height, which often improves traction and cornering feel.
XRAY 306198 is suitable for racers aiming for small, repeatable setup changes to balance and traction without complex modifications.
