Anybody put a different (like 17 or 19%) pulley on a JCW-equipped car? I am just curious. :smile: Of course there are warranty implications by doing this, but somebody brought it up at one of our local club events the other day.

 

There are a few people who have done it. I have not heard of any 19% upgrades on a JCW, but have seen a few 17% upgrades.

I personally wouldn't do it, mostly because why would you spend the money on the kit to just start tearing it apart. But to each his own.
