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

I saw some reviews that mention difficulty in threading or fitting. They are tight, but they work fine. I had no issues installing the speaker wire and no issues with the set/crimping screws. I even had one fall out when I loosened it too much and, though it was challenging without my glasses, I did get it to thread back in with no problems. I have purchased other BluRigger products, like HDMI cables, and they are of great quality.
