If I'm not quick enough with my shifts, and the revs go down to idle (from around 3000RPM) before I let off the clutch for the next gear (say 3rd --> 4th), is it doing significant damage to the clutch considering that letting the clutch out brings the motor back into sync with the wheels?



I ask because I'm still not perfected on my rev-matching on the Genesis and it happens quite often.

 

No, it shouldn't do "significant damage" to the clutch. It will probably wear out the clutch disk a little bit faster. I would be more worried about ruining the synchronizers.

 

Unless you are braking, and sometimes even then, you should have your foot on the gas pedal to prevent this happening. Nevermind the clutch, it's hard on the passengers.
