The M3 ZCP set-up is amazing and congrats on finding a set, and attempting to achieve proper fitment... your a trailblazer. I've been contemplating on purchasing a set myself and was in the process of researching. Thanks to you, my job is now that much easier.
Can you please give me an idea of the weight difference between your previous set-up and the ZCP.
I'll be glued to this post and your progress. Good luck.
