Hi guys, I am picking up an R53 (?) 04 plate Cooper S tomorrow. I have heard that a 15% supercharger pulley is a good place to start tuning wise. Can anyone tell me where the best place to get this is please?

Thanks.

KMT come highly recommended KMT-Mini tuning (http://www.kavsmotorsport.com/)

I own an Alta V2 myself but the KMT's are better when it comes to removing/replacing. If you decide to fit a 17/19% at a later stage, the 15% will come off with relative ease (with the right tools):D
