Hi just saying as a newbie, have a z4 e86 3.0si coupe and have had for 2 years and still love it previously owned a z3 2.8i but died due to a deer.

I'm looking to tune it and make Z4 CSL of some kind or a lightweight edition but using BMW OEM parts.

I hope to enjoy along stay with the forum and meet up and help guys with any techy stuff or retrieve help from others.
