Hi all,

Anyone using Unorthodox Racing's Underdrive pulleys?

I've seen some reports on other sites, but would be interested in individual feedback as well.

Is there a noticeable difference? How much?
Any negatives? Problems?

Thanks,
Mike

I've heard that it caused the alternator to fail prematurely and the gains werent that noticeable. Performance Probe just released a lightened pulley thats the stock size for cheaper and I've heard some good things about them.
