The Cost of Wear: Why You Cannot Afford Not to Replace Your SADEV 3rd Gear Wheel for Clio 2 Gr N?
In motorsport, every single part of your transmission is subjected to extreme stress. Keeping a worn 3rd speed wheel (22 teeth) in your SADEV ST66 sequential gearbox means taking the risk of losing big:
Risk of Failure and Retirement: The Track's Penalty
Even slight wear on the teeth weakens the entire gear set. Failing to replace this original SADEV 3rd speed mobile wheel (16/22 ratio) means exposing yourself to mechanical failure during an event. You would not only lose your time and investment in the race but also risk severely damaging the other components of your SADEV gearbox.
Every millisecond counts in rallying or on the circuit. A gearbox that is no longer perfectly reliable leads to a loss of responsiveness during gear changes, and ultimately, a loss of precious time and position.
