M7 2% crank pulley for 2002-2006 R53 MINI Cooper S and R52 2005-2008
MINI Cooper S Convertible. The M7 2% Crankshaft pulley is CNC machined and hard
anodized. The M7 2% crank pulley will allow the engine to rev quicker. But keep in mind it is NOT a balancer so this will be harder on crank and rod bearings. Also this can cause tuning issues. The M7 crank pulley weights less than one pound.
