I'm just hoping this old design slave will last me until the flywheels are released... might as well get the "free install" while you can

And on top of that, I'm really hoping the new design fixes everything. If I'm going to go through slave cylinders every track day or so, it's going to either get REAL old and/or I'm going to get REALLY efficient at dropping the transmission.
lets hope it doesnt come to that

just make sure to change out your crankshaft/flywheel bolts. i would change it out(new), whenever you upgrade to light flywheel/stronger holding clutch. loctite etc..... you dont want to shear those bad boys off while driving to work. had to repair a few of my friends nissans. it wasnt a 07 though. a light weight flywheel is a good upgrade, you have to get used to it. i always kept hitting redline, it comes up way quicker then u think.

It's probably dependent on the dealer, but others have tried to get aftermarket clutches installed while getting the recall, but were refused.

So other than saving money on labor, is there any advantage to getting both the flywheel and clutch at the same time. Other than the obvious advantages of the aftermarket clutch itself of course.

someone correct me if Im wrong, but I was always told that If you were replacing the clutch and not the flywheel that its recommended that you at least have the flywheel resurfaced so that it mates up better with the friction disc of the clutch assembly.

if re installing old flywheel, then yes go ahead and resurface it. if not you can end up with premature wear on clutch, or uneven wear.

Wow really? That sucks. Most of the dealers around here are normally pretty cool about that stuff. No real advantage to getting both at the same time, other than the savings in labor if you're eventually planning to upgrade the clutch as well.

I have a few on order through JWT as well and were told they were "right around the corner".

I can't wait to get mine in and get the updated slave cylinder as well.

They were right, I just got the tracking number for our order so it looks like I'll have my flywheel on Monday.

When somebody gets a lightened flywheel installed, post up some before/after dyno graphs. Kill the speculation, and lets see what kind of power this lightened flywheel can make.

Lightweight flywheels do not produce any power. Therefore, dyno numbers will not change.

is the 07 flywheel dual mass like the 03's? If so expect a noisy driveline if you put in a solid one like I did.
