Description

GFB 02-10 WRX/STI 2 Piece Under-Drive Pulley Kit w/ Belts (Crank & Alternator)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.

Nice, but a little snug
Size: Large, Color: Navy 177
I like the material, it does a better job than most shirts of being wrinkle free. The sizing is a bit small, I have a gut and if feels snug, whereas my other shirts (mostly LL Bean) do not.

Nice shirt!
Size: X-Large, Color: Blue Red White 161
A very nice checked shirt. It is mostly iron free. The material, although cotton has a stiff feeling. If you forget that drawback, it's a nice shirt. So reasonably priced.
