Hello All, thanks for the welcomes! Please feel free to tell me if I'm wrong... but the first thing I want to do to my 2005 R53 is change out the pulley on the supercharger. Really want to see how much a 15% diameter boost will do. Any comments suggestions would be appreciated, but my question - does anyone recommend a favorite brand, online shop to order from, etc. I hope I can find one that will rent me the specific tool as well. thanks!
