I would like some input from some engineers and mechanics. All modern MT cars have syncronised transmissions. when you shift a MT you usally have 2 points of friction the catch/release. If you double clutch you now have 4 points of friction because your doing it twice. Not to mention your throw out bearing will get used 4 times as much. Why do people insist that double clutching an syncro transmission will not cause more wear and say it’s better for the car? My second question is all MT cars now have these clutch helper sprigs on the clutch pedal. Now these are there to lighten the load for the user so the clutch dose not feel so heavy. This also makes the clutch ingament tuffer to feel. I have heard of people removing said spring and the clutch feels like it should but there is a little play left in it as it dose not have that spring to keep it at fully out. I have heard that a few places offer a spring with different spring rate to improve the feel. I would like to know why spend the time to engineer this into a car. To have someone just take it out and think it will have no impact of increased wear on components?
To me it just doesn’t make sense maybe I’m wrong and double clutching an modern MT has no effect but to me your using those parts 2x as much so how would it not wear faster. The spring issue to me if there is even a little travel in the pedal that would simulate lightly resting your foot on the pedal. We all know that’s why there is a dead pedal and it can lead to increased wear. Yes it depends on how big and heavy the foot ect. Thank you
