Clutch question
1. It doesn't hurt the clutch to sit with the clutch pedal depressed. Often I will shift to neutral and release the clutch but that is a personal preference. I guess if you sit enough with the clutch pedal depressed, you could wear the throwout bearing. Many will say that you don't want to be out of gear so that you can maneuver instantly....
2. The way you really burn the clutch is to partially release the clutch and goose the gas. AKA slipping the clutch. Slowly releasing while feeding in the gas is normal.
3. I just move the shift leaver. If the trans is balky, you can double clutch (shift to neutral, release reengage and shift to the desired gear)
No need to slip the clutch for this.
The Corvette is a ultra high performance car and the clutch is intended to support that. Holding it in at a stop won't hurt it at all, and small slipping starting out will cause normal, intended wear on it. Popping or sidestepping the clutch at 2000-2500 for max acceleration now and then is also fine, as the car is intended to be driven hard now and again from a stop. If you do it every time you take off, or on the other hand, granny start letting the clutch out for 5 seconds, you will get accelerated wear. Common sense prevails. I found after opening the shroud (Free Cold Air thread), my take off from a stop, cold, in 1st is much smoother. I have no answer as to why, but it is a fact. Maybe the computer learned for the much cooler, denser air that I now get underway and an adjustment at idle took place. For whatever reason, it is far better than it was and definitely eases normal clutch wear.
