JWT or Tilton clutch and flywheel
i had the full-street for about 8 months and 8k miles... loved it, but agree with everything sentry has posted above, both the good and bad... that being said, i wasn't about to remove it no matter how pissed off I got at it (until the ATS dual-carbon goes in with the built motor 
)
)
yeah I'm too stubborn to remove mine
it really does drive fine when you're driving aggressivly - no complaints as long as you're rpm's are above 2500
But I'm going FI and thus forcing me to remove it and sell it
seems there's quite a few fairly built up NA people going FI

i myself am just going in a "different direction with my mods".

- mpg goes down
- you will tend to drive the car above 2500rpm almost 100% of the time to avoid the chattering vibration shuttering sound
- your car will sound like it's broken. People will come up to you and ask you if something on your engine or transmission is broken, or if you need a new throw out bearing, or if something came loose and is rattling around.
- It will squeel a little almost every time you take off from a stop.
- It will shutter and vibrate really loud if you're in too high of a gear or if you're below 2500rpm and in anything other than 1st or maybe 2nd gear.
- You can raise your idle and lose more mph, but at least you won't get the clunking cement mixer sound at stoplights and people looking at you like you have a trashed out car that you broke somehow. Idle raised makes the car sound meaner at a stop and gives you a sort of "auto pilot" similar to how an automatic goes forward when you take your foot off the brake pedal.
- There's rumors that it isn't balanced and could be bad for the engine just like the UR crank pulley and might possibly have an effect on the ECU's ability to know what's going on by trying to correct itself too fast or too slow with rpms to reach the idle rpm when you push the clutch in really fast.
- It is easy to stall, but mainly it's when you're not thinking about driving that you tend to stall the most.
- You'll get frusturated more than you have been before with red lights and cars in front of you driving too slow for the gear you're in. So you'll be downshifting a lot more often instead of just cruising in your current gear like you're used to.
- You'll get really good shifting the car into neutral for almost anytime you need to coast because as soon as you take your foot off the gas pedal, you have about 3 seconds before you get a small buck from the transmission because the flywheel is just starting to lose it's natural momentum and since there's not a 2nd disc to cushion the jerk, you get a sharp buck. So you will shift into neutral a lot.
- You'll learn to feel like you're driving on eggshells in the city.
- You'll dread big slow speed bumps more than you ever have.
- You'll possibly hate making the car go from a stop if you're trying to drive slow or don't want to wait for the car in front of you to be 50 yards ahead of you before taking off because you don't want the cars behind you to honk at you for taking your time. So you try to go slow and either jerk or get some squeeling which is basically wearing out the clutch more. Rush hour is one example that comes to mind.
- You'll learn to REALLY cover the clutch pedal for that fraction of a second reflex time that you'll need to push it in before the car bucks back at you because of how sensitive and picky the clutch is.
- When you decide to go FI, you'll wish you had just spent the extra $400-$600 for an exedy or ATS twin carbon clutch cause you'll have to pay out your nose for one and sell off the tilton cause it won't handle 400whp.
- You'll get used to the occasional minor lugging/jerking the car will give you when having to drive under 2500 like in a parking garage.
- You'll get used to people like your mom asking you why you're driving so aggressivly and fast when you take off from a stoplight even though you're trying to drive as smoothly as humanly possible.
- You'll get used to either stalling or reving to 5000rpm (because it's so light) if you don't manage to get the car on its way from a stop.
- You'll grow used to telling everyone who drives your car to be careful or to not freak out if they stall it or if it makes all those crazy noises - people like mechanics, nissan dealers, valet parking (if you must use valet).
- You'll learn to laugh at yourself for stalling on the bump to the entrance of your driveway because you slowed down almost to a dead stop right where the road meets the sidewalk and now you gotta get over the bump without plowing into the garage.
- You'll have no problem explaining to your friends and family who drive your car why it drives "like crap" and accept that they might not be able to drive your car if the situation ever arised.
- And finally at times it'll make you somewhat feel like what you felt like when you first learned stick. Hoping no one comes up behind you at a red light and hoping you don't stall.
...but yeah it has good performance as far as getting the rpm's up really quick and sounding like a race car when you rev it up.
hope that sums it up

Thanks very much for the info Sentry65. U da man!
So just a quick question.... essentially if in the long run i will be going forced induction...if I want to get this setup then I would need to get the semi-street? Or do either one of them not be able to handle FI?

As far as drivability goes yes. As far as performance goes i felt the full street was a tad grabbier during shifting. Keep in mind with these clutches you tend to shift alot more. With each shift you can feel the torque of the vq its a awesome feeling. I let one of my buddies who just bought a 05 z take my car for a spin and he was like the clutch is bad ****(full street).when i test drove one of my other buddies stock z i felt like each shift took forever. Imo the full street is a awesome set up for NA. Semi street i would not recommend to a everyday driver unless hes ok with having a hella sensitve no slip clutch. I let my girlfriends brother in law (sports car enthusiast)drive my z when i had the semi street clutch and keep in mind this guy has driven ferraris,porches etc. well he stalled my car 3x and then he had the hang of it. His words that day were," this fckng clutch is the second hardest clutch i have ever driven but man is it fun once you are out of 1st."

THe tilton is just too much of a pain to drive everyday.
I had the Tilton for about a year before I switched to the JWT combo. So it's kinda hard to say how different it is from stock. The Tilton is really hard to drive because it is very grabby, has very low weight and is a 7.25 inch clutch. So it stalls at the drop of a hat. The JWT does help getting the power to the ground. it's very easy to drive daily and can handle FI. If your not driving in traffic or on hills or just a lot of stop and go, then go tilton. Otherwise, Tilton is a hard setup to handle.
