I upgraded my clutch a month prior to turbo build and I can definitely tell you there is no way I would volunteer to drive this clutch if it wasn't necessary.

Which clutch?

Went with the Z1 full face lightweight combo. It's reasonable except it sucks in traffic. I've driven worse but I would probably have to say it is at least 3-4x stiffer than stock with the help spring removed.

I'm ok with it considering I have to run it to hold power but I wouldn't if I was NA.

Interesting. I'm going with the same to go with my F.I. twin install. I have the helper spring which made a huge difference on the stock setup. Think I should remove it after the new clutch and fly?

If you are used to driving with the spring in, then leave it in. I assume it'll help a little with peddle stiffnes.

I highly recommend the clutch. You definitely feel the differences with the ligthen flywheel. Revs much faster and throttle response is awesome. Like Chuck says, it's really noisy but you get used to it. When you drive off and your Z suddently sounds like a F250 diesel, don't be alarmed.

As for engagement. The Z1 clutch is slightly lower than the stock engagement point but it has a good window. I've driven some aftermarket clutches that were on/off switches, this one is nothing like that.
