just a heads up on those H&R springs, not sure if its the same part number for the M or the non-M, but.. I went with the 15mm spacers peeps were recommending, and I am finding my butt is in the air way to high (noticeably more than the front)... thinking of swapping back in the older 5mm pads.. maybe they slightly changed the fabrication process??

I was thinking possibly its due to not being bedded in, but now about 6months and around 2K kms later, its still the same.

anyone have any input on this on the *couf* M?

My Z4 M Roadster has H&R springs, installed by the previous and original owner (Ron888) within 3 weeks of when he bought the car in July 2007 IIRC. The car is noticeably lower in the rear. He installed progressively more aggressive 19" wheel and tire combos and the rear fender liners were worn through when I bought it (since replaced).

I just ordered the 15mm spacers from Turner Motorsports, something I had considered awhile ago, but just forgot.

(P.S. What do I need to do to install these? Turner says that they can go either on the bottom or the top, which is preferred?)

I also ordered the 15mm rubber spacers, but never installed them. Still have the OEM ones. In stead I changed the front tires from 235/35 to 225/35. And now it sits perfectly I think. Have 265/30 in the rear.

pretty sure the non-M springs are a different part number to the 3.0si, but yeah your right, yours looks very nice and level.
