The 3Racing Sakura XI Rear Graphite Shock Tower SAK-X11/WO is specified to increase rear bulkhead rigidity and improve shock mounting consistency. Its graphite construction reduces deformation under load, helping maintain setup geometry during repeated laps.
For racers aiming to refine handling, graphite gives a firmer pivot that sharpens turn-in and stabilises mid-corner balance. The 3Racing SAK-X11/WO assists predictable weight transfer, allowing finer damping and swaybar tuning.
Install with the Sakura XI factory points and confirm all fasteners are torqued to correct feel. Perform a quick inspection between heats to verify the tower shows no signs of stress or micro cracking that could alter setup consistency.
