I was wondering how big of a difference reduction in weight of 2 or so pounds per wheel would have on performance? Would acceleration and braking improve, or is it just a myth?

It helps, it is called unsprung weight, but why waste money on wheels and only shave 2 pounds ?? change the brakes ??it aint cheap, but you can stop on a dime, and I believe Kirk said his Eradaspeed rotors and hubs shaved like 25 pounds per wheel, if I got the numbers wrong Kirk, or anybody correct me please, but I think I got the weight right. Its all about Rotating mass and inertia and moving weight from a dead stop

Well, I have steel wheels now (hey, my 00 LX was a gift). How heavy are they? The rims I was looking at were under 20lb.

I can feel a 4 lb difference in the butt dyno. Just went to some '99 rims and they are lighter yet. '97 SHO rims were 18 lbs and the '99s are 16.5 lbs.

Going from steel to aluminum would be quite noticable as long as you didn't waste it by going to a bigger tire and wheel than you need.

I don't care if you lighten each wheel by 1 lb you will feel the difference. Maybe not so much in acceleration (but you will a little), but in handling.

Was this the company you're talking about?

http://www.eradispeed.com/

If so, do you know of any compatible part numbers? I downloaded the catalog and could only find rotors for contours/cougars, focuses, and mustangs in the Ford section.

One pound saved in unsprung weight (tire, wheel, brake, suspension pieces) is worth seven in sprung weight.

mikehawk,
Don't want to be an a$$, but you might want to start a separate thread instead of jacking this one.
