The XRAY 306199 Graphite Holder gives precise placement options for slim packs in T4 2020 cars, letting you tweak centre of gravity to suit different track conditions. Its slim profile helps avoid clearance issues while you test setups.
Using 3.0mm graphite provides a stiff, lightweight base for the battery that resists flex under braking and cornering. That stiffness helps keep handling consistent over multiple runs.
Adjusting the battery position is straightforward, so tuners can compare small changes without long rebuilds. This makes it practical to iterate setups during practice sessions.
