GFB 04-10 WRX/STI 3 Piece Under-Drive Pulley Kit w/ Belts (Crank Alternator & Power Steering)It might be hard to imagine how reducing the mass of a pulley makes a car go faster, but accelerating a heavy factory pulley from say 3000 7000 RPM in a second or two saps a measurable amount of torque. GFB Lightweight Pulleys reduce inertia by up to 85 percent, so most of the torque that used to accelerate the pulley can now be applied to the wheels. This Part Fits: Year Make Model Submodel 2008 Subaru Forester Sports 2. 5 XT 2004 2005 Subaru

On sale purchase and glad I waited.
Size: 33W x 30L, Color: Stone
I'm 6'1 186lbs size 33x30, I don't workout but for whatever reason my calves pose a problem with a few brands and styles of pants. These feel wonderful and the color is awesome. Minus the tight area in the calves these are perfect for summer in Oklahoma. I usually wear these with light brown or gray penny loafers no socks or some suede Allen Edmonds chelsea boots and a white vneck tshirt. I got these on an extremely good sale so that helps. I wouldn't pay full price for whatever that's worth.
