Unorthodox Racing Pulley Sale! $1 Shipping w/ Free Belts!
They originally came w/ Nissan Belts, but we kept having squeaking issues. We use Gates now, they seem to fit much tighter.
I'm using underdrive on my 04 350Z Daily Driver, also track it, and no issues. I would only use the Stock sized pulley on a Supercharger vehicle, or guys w/ a large Stereo System.
