    This kit will leave you astonished! It is super high quality and light weight... I had the perrin light weight installed on my 2008 STi and it was really good. I found the Go Fast Bits kit by accident and I kept thinking.... Hmm would 3 light weight pulleys be better than one? Sure is! Plus the quality and looks defineyely stands out. I love this kit, you'll feel the difference even going from one light weight pulley to this complete kit.. Now if you're in the market for a light weight pulley don't even look further.. this is the right kit to go with! Drive safe lol

    Why do just 1 pulley when you can replace them all?  8 years ago

    The GFB pulley kit replaces the Crank, PS, and Alt pulley's with lightweight aluminum units that are of the highest quality. The real benefit is weight savings and when I weighed them in comparison to their stock counterparts I confirmed RSD's findings of more than a 5lb total weight savings on my 2008 STi. Comes with belts and install instructions. Oh and the packaging is damn impressive too! Buy them now!

    QUESTIONS & ANSWERS

    • Q: fits  Dannyjdm2 years ago

      this kit fit, 2006 Subaru Legacy GT, thanks.
    • Q: Timing  ATXRX2 years ago

      Do you have to have a timing adjusted to run these
    • Q: Would these require a tune with a turbo back?   Lapissti3 years ago

      Does this kit require a specific tune if I already have a turbo back or will it be ok to just run my current one
    • Q: Power steering pump underdriven  SubÉric3 years ago

      Is smaller power steering pulley mean that it will be harder or more difficult to turn in the car, steering wheel effort?
      • 1 of 1 people found the following answer helpful

        A:  This will make the steering tighter and heavier yes, but it probably won't be too much of a difference
