The XRAY 345511 8mm 2-speed shaft is built to improve the drive characteristics of RX8 series cars. It reduces unsprung and rotating mass while retaining strength, making it a solid option for drivers focused on consistent lap times. Precision grinding and heat treatment deliver smooth engagement and longer service life for regular track use.
A sensible upgrade for racers seeking a balance of lightness and durability, helping maintain efficient power transfer under race conditions.
