Alright, calm down. Ucheckit, the reason that you can't find a definitive answer to your question is twofold. First, no one here has a crystal ball, so we can't assure you of success with this setup. Next, what SACHs clutch? The Sport Clutch or OE? What LWFW? Not that it matters necessarily, but are they sold as a set or individually? As a general rule, the clutch won't burn out sooner strictly because you're using a LWFW. You may experience a minor hit in terms of ease of operation, but you can probably compensate for it without any difficulty. You will experience a slight performance gain. So that's as much as we know. We don't know whether this setup will last as long as OE. Give it a try and let us know how it worked out for you.
