Thanks! It looks like the M3 control arms provide more castor and effectively move the wheel forward. I was hoping to find out from the experience of others... not my own :D

Looking at BMW parts manual there are 2 part numbers for main wiring loom of Z4 Coupe... One up to 04-2007, one after 04-2007 Could anyone provide details on differences between pre and post 04-2007 wiring looms?

Thanks! :thumbsup:

Any chance of a short video of the process?

Great to see others expanding on my original post. Awesome addition :thumbsup:
