I believe the spec flywheel, weighing in at 10.2 lbs, does not weigh enough. Beacuase of this, the flywheel makes some nasty harmonic noises! SKIP!

I think about 12lbs is ideal

12 is what WOA makes, I think some of the others also run at 12 lbs.

Just yesterday I hear some noise for the first time. I was sitting at a light with my windows down. I didn't know if the noise was coming from my car or someone else's car. It turns out I heard it because it was echoing off the minivan next to me. The noise was only there when I was in gear with the clutch depressed. Even then, I couldn't really tell it was coming from my car. I had to change gears a couple times to confirm it was mine. I like the LWFW. The noise was far from a chatter as most people describe it.

What clutch were you running?

skabaru

can you better explain your problems?

I love mine, stock cars feel like crap now.

I am running a solid FW (duh) and a sprung clutch...

flywheel (I put a new surface on it right after this pic was taken)

I am on my second DXD and it hold great (then I wore it out)

I get some chatter when the car is in neutral and the AC is one... and by chatter in this case I mean a metal clattering sound kinda...

I love the setup though, wouldn't go back to stock flywheel...

From what I understand, 1 side should be sprung... if you are using the stock flywheel, since it is dual mass, you can use a solid clutch... but it you are using a light weight flywheel, since it is solid, you should have a sprung clutch...

That's a bummer :-( I was considering getting a spec stage 2 clutch and adding lwfw later. I'd be interested to find out if there is a sprung stage 2 clutch.

skabaru

did you buy them separately?

I would THINK that SPEC would know what to sell you for your setup... I have never dealt with SPEC, but the southbend website lists their clutches for use with a LWFW or without with separate prices and whatnot.... I got my setup together from southbend, both at the same time and told eddie to give me what I would need, he sent me what you see in those pics above.

I would THINK spec should know that, but I am by no means an expert, just a guy who has been through a few clutches because he REALLY likes 4-5K launches...

skabaru

may as well do it all at once....
