i have a 2003 cooper s with a 15% pulley and cold air intake. i am very interested in the lightened crank pulley but i have heard that they can damage your engine. the reason is that you are taking off a factory engine balancing component. this scares me. i beat the cooper up but i dont want it to grenade. i was wondering if anyone knows of this being true? also does anyone here have this mod? if so was it worth it? any issues and what do you think? would you recommend it?
