It's an ok mod if you can do it for cheap or you have ~$225 to blow. You're not really going to notice a big difference with an al/ds. The al/ds weighs 13.5 lbs, the stocker weighs 25.25 lbs. Less rotation mass yes, but the mass is very close to the axis. You may or may not notice gains in acceleration. I noticed a slight (if any) gain, but I also installed an al/fw and 10.5" diameter clutch. I also feel more harmonic vibrations in the car. Steel does a better job of dampening than aluminum. I'm also using MMS lcas that use spherical bushings on one end (they don't help with vibrations).
BTW: My highway MPG dropped about 2-3 with these aluminum componants. Remember, less rotational mass to stay in motion (Newton). My best was ~33. Now it's the mid 29s.
