Hi I've been a member for awhile but been busy working and lost my BMW mojo so now I get more time at home I've fell in love with it all over again, it's Z4 3.0si Coupe in black with black leather but all is about to change in the near future I'm going to be building a non M CSL as it has the lightest straight 6 production engine ever built , I've took my inspiration from that and going to be continuing that through out using as many OEM upgrades as possible. It's going to be difficult on finding these parts but it's a challenge. If anyone has ideas please pm me I would greatly appreciate it. I hope to be putting up a progress report but be warned as it will be slow as I'm away for 3 weeks at a time. Thanks again
