USNSTI is right in the 25mph example, the force from that is actually incredible. Having been in that situation, your limbs kind of go to the path of least resistance. My head snapped back with quite a bit of force, I didn't even know what my hands and feet did, all I know is that my cars rearend was crushed and my car came to rest in the oncoming traffic lanes. After the initial shock wore off and adrenalin started to ebb, I remember I got out of the car swearing, wanting to yell at the driver of the other vehicle! Fortunately, it was a guy in his 80's so I felt concerned for him.

You still didn't answer my question sir. Who's clutch has failed from having it in gear at a stoplight? I am still waiting. Or should I just take your word for it?

What I'm saying is, most people sit at an intersection with their foot on the brake pedal.

As for my question on Clutches and Flywheels, I have seen different opinions, curious as to who is running with what type, what HP and TRQ levels, using for how long, and their impressions of likes and dislikes, would you do it the same or change something?!

I am currently researching the following: ACT, SPEC, Clutch Masters, RPS, and Exedy

Thanks.

I never said anyone's clutch has failed, nor did I say I could provide proof. One thing is for sure. If you have an idea of how a clutch works. When it is depressed for a long period of time over several weeks or years, or what ever. It will be more proned to faliure, and fatigue. Basicly it won't be as stong as someone who dosent peform this method. The only people ive ever seen do that, are ones who are learing to drive, or dont really care about their car. I'm done in this thread. Over and out peps!

I think 90% of people who are stage 2 are on the stock clutch. I believe it is good for at least 300whp unless you are subjecting it to a lot of abuse.

The more stress you put on the equipment the sooner it will wear out.

I have to lol at this. When the clutch pedal is pushed in, there is absolutely NO wear taking place to the clutch plate or disc. Is this what you meant by the clutch not being as strong? The only part that does get wear when the clutch pedal is in is the throwout bearing, and maybe also the cylinder. These parts won't make the clutch "less strong" it will still have the same grip regardless of those parts. Maybe I misunderstood your post but it seems you might not know clutches as well as you think you do.

You mean to tell me that your foot could go anywhere, except for your foot that is on the clutch pedal. That one stays on the clutch pedal, but if you had your foot on the brake pedal that could go anywhere? Hmmm?

Also when you shift out of gear, then back into gear, you have effectively cycled each of those parts twice, instead of once. So you have effectively put twice the wear on at least some of those parts.

No my example assumed that both feet came off the pedals. Not guaranteed that that is going to happen, but if you have ever been rear ended when you didnt see it coming, you'd know there is a good chance your feet are coming off the pedals. That means foot off brake, and clutch. If transmission is in gear, the engine stalls and it keeps the car from rolling. If it is in neutral, then it just rolls. I was asked to come up with a hypothetical scenario, which I did. I happen to think it is a very realistic one. Also I think it is just one, of many possible. But if people can't come up with some of this on their own, then me explaining it to them isn't really going to help much anyway.

^^ Just asking. As far as wearing a clutch out disengaged. You are correct. NO it will not wear it out. If anything maybe an I mean maybe, you might prematurely wear out the throw out bearing. As far as multi plate clutches. You can get excessive heat if you disengage the clutch for an extended amount of time.
