I meant rev match: Clutch in, neutral, clutch out, blip throttle (this takes the longest, especially trying to downshift to first), clutch in, new gear. Basically its heel-toe, but I'm not necessarily using the brake (like passing or going up a hill.) I figure a light flywheel will make my sho life easier in the long run. Plus people won't be so confused when I'm approaching a corner and reving my engine trying to throw it into first at 20mph :)

Why would you want to do that???

What you describe IS double clutching. Doing it on a tranny iwth syncros is pretty pointless, I mean I suppose it MIGHT make the syncros last longer though.

I run a fidanza 9lb and spec stage 2 on the street daily and I have no problem with it at all, you really get used to it pretty fast. As long as you aren't one of those people who revs to 4k rpm and then slips the clutch for 5 minutes, an aluminum flywheel is fine for a N/A car. The only downside I see to an aluminum flywheel is if you're in traffic and you spin the clutch a lot revving high it will heat up and can warp. But to me the pros outweigh the cons by far.

I was under the impression that it greatly reduced wear on the transmission, but even if the your right and the wear is negligible, it still makes the shift much smoother IMHO (Especially when passing on the freeway 5th to 3rd).

rev matching should yield the same results, but yes double clutching will make for a very smooth shift for sure especially in a syncroed tranny because it will take up any slop you messed up on.;)

I got the fidanza 9lbs and its noticeable difference over stock after secondaries open. I personally love the feel of the car with it.

Done right, double clutching or rev matching does save wear and tear on the tranny and the clutch.

the only difference you are going to see with the fidanza flywheel is that when driving normally (babying the car) your shifts have to be much faster or the rpms drop off to fast to smoothly engage in the next gear. the flywheel lowers the rotating mass of the engine alot and there for makes it rev and fall off alot faster, so with the stock flywheel if you let off the gas and hit the clutch the rpms fall alot slower than with the fidanza. this is the only difference i have noticed. i havent really noticed any gains at all but i sure they are there even if minimal.

I should add this, I run my fidanza with a stock crank pulley, running it with an UD aluminum crank pulley might make it very difficult to drive on the street as the engine has lost almost all of its rotating mass. Id love to rev a car with all that on it though, it probably revs like a crotch rocket.

N/A Fidenza w/ spec stage 1 clutch, just done by Kirk and Chris last winter. It was a stock FW and Clutch. I like it and liked it at Gingerman, shift faster before it drops, and alls good so far, not that hard to learn a new feel.

I have a fidanza waiting to go in. Will probably put a south bend rally in there too. Obviously can't give you any driving impressions yet. I too am surprised at how many people have 17lb flywheels. I thought the fidanza was very common.

Ive been running a lightened stock flywheel for some time now. IIRC the shop got it shaved to 18-19lbs. Pushing 50k miles now on it, coupled to a heavy duty pressure plate, and fibertuff disc. Loving every mile! Cheap too. ;)
