The 3Racing SAK-M5P07A Graphite Upper Deck is specified for the Sakura Advance M5 Pro chassis where controlled flex and repeatable balance are critical. Manufactured from high-quality graphite, the deck increases longitudinal and lateral stiffness to improve feedback and consistency lap after lap. The 223-228mm length range allows precise wheelbase alignment within common racing setups, making it a practical choice for drivers refining chassis behaviour and setup windows.
