Please excuse my ignorance....but what is LWFW?
LWFW = Lightweight Flywheel.
It replaces the heavier OEM flywheel, and in doing so the engine uses less power (hp) to spin the flywheel, so more HP is transfered to the rear wheels. Hence, it doesn't change crank HP (which is measured at the engine crank), but as their is less drivetrain loss, it does increase the RWHP (rear wheel hp).

Thanks! I though it would have something to do with the fly wheel. Who makes them? I'm assuming the labour for the install would be expensive?

actually they are a porsche product. I have a RS flywheel on my car and it weighs about 20 lbs less than the stocker. Engien revs so much faster it's unbelievable. It really is a worthwhile mod. Bang for the buck it is unbeatable.

I did it when I replaced my clutch, otherwise it is the same labor as a clutch install.

I have an Aasco Flywheel, which is sold by almost all the tuning shops as there own. It is 20lbs less, makes a bit of a rattling sound, but it really allows you to get to your power band quicker, as it takes less inertia to get it revving. It is also nicer for Rev Matching.

Thanks for the info. I've never looked into how much a clutch job is on a Porsche but my experiences with my other vehicles are that it's probably expensive. I've got under 16K miles on my car so it'll probably be a bit till I need a clutch job, I'll consider the upgrade then.

It's not cheap, but it makes sense to do the LWFW if you have to go in there to replace the clutch.

Parts (AASCO LWFW, Sachs Stage 2 clutch, throw-out bearing, & pressure plate) come to about $1,800. Labor is another $1,100 or so.

Does LWFW make car to be more difficult in traffic? You obviously loose that 'elastic' feel of a regular flywheel completely, right?

I would imagine it takes a bit of "re-learning" with the clutch to get the feel of a lighter flywheel. But I'm sure after a few drives with it, there would be no problem getting around in city driving. This is just speculation based on what other have said.

I wanted to do both suspension and clutch mods before spring but generally re-thinking it all now after I tried how modded race cars feel at events. Not all this stuff is really good for daily driver car and LWFW is not something one can easily un-bolt if it will not go as well as was planned... I wish I could try one but Devens season is off now and now one from this forum seems to have LWFW anyway, I mean, in MA.

The clutch feel only changes when clutch is replaced with a new one. I am still running my original clutch. The only negative difference is a bit of a rattle at idle.

Just do the Fly wheel, it is a no brainer. Anyone who has one regardless of platform loves it.

The LWFW does not make driving in traffic or stop and go any more difficult. Neither does the Sachs Stage 2 clutch.

The Stage 2 clutch is heavier duty than OEM, but it's not the race clutch, which is the Stage 3 unit. The Stage 2 does take a couple days to relearn, as the release/ engagement point is just a little different- but it is by no means inelastic. The same way all clutches are different, BMW, Audi, Ferrari, etc., the first couple of shifts are not natural or fluid, but after a little bit you get used to it. There is nothing harder or wierd about it whatsoever.

I drive my car daily, under all conditions. Neither the LWFW nor the stage 2 clutch have compromised my car's ability as a daily driver.
