Supercharger belt for 02-06 R53 MINI Cooper S and 2005-2008 R52 MINI Cooper S convertible with 15% 16% or 17% supercharger pulley.  Thess belts are slightly shorter than the standard MINI Cooper S belt to keep the belt tension correct so it doesn't slip.  Please select the belt size based on what size supercharger pulley you have.  Also we now offer a heavy duty version of the 17% pulley belt.  It is designed with a better grade rubber to have less stretch and last longer.
