Because we have synchros in modern gearboxes, these synchronizers spin the input shaft to correct speed when downshifting. That’s why double-clutching isn’t necessary today, but I still recommend it. While synchros do the work matching input shaft speed, you can also do it manually yourself. There are many benefits to doing so, especially for transmission longevity and smoothness under hard driving. 📹 Full double clutching guide in bio! - #carsofinstagram #carsofinsta #carshow #carspotting #dai
