Here's a posting about wheel weight on a WRX forum. Good comprehensive listing.

thats why I laugh at people with 18+ inch wheels, they may look good but all that rotating mass cause almost a 10hp loss at the wheels...

Interesting concept. Horsepower loss from weight. I don't recall weight being a factor in calculating horsepower. It may require more hp to accelerate a given mass at the same rate if the mass increases, but there is no hp "loss."

Horsepower is simply the ability to do work. The simple test says, if I make more horsepower my top speed is higher. If I reduce the weight of my car does top speed change? No. If I make more horsepower does top speed increase? Yes.

If I reduce weight does the rate of acceleration change? Yes. That's what this is all about, not horsepower loss.
