I know for stock z4m wheels you need at least a 12mm spacer for the front. If you know the offset of the stock wheels and the CSL wheels you could technically figure it out or be close.

If the below is correct then "compared to your existing wheel, this new wheel will have an inner rim which is 8.3mm closer to the suspension strut. The outer rim will poke out 4.3mm more than before".

Z4M wheels are 8x18, 42 offset front and 9x18, 30 offset rear.
Genuine CSL wheels are 8.5x19 ET44 front/9.5x19 ET27 rear

One thing you can do to determine minimum spacer required is use some washers as spacers.
You will also need longer bolts.

You will be ok to lower the car with washers in place, but do not drive it this way.

Stoptech also have clearance templates that you can download ..
Print them out and test on the wheel.

It's actually quite hard to infer wheel clearance this way. When I had installed the RacingBrake front fixed caliper on my MZ4 Coupe, the front MZ4 style 224 wheels took a 5mm spacer to clear (really only needed 3mm), while a set of OEM E46 M3 wheels I was using as my track rims needed a 12mm spacer due to the curvature and shape of the spokes.

I like inTgr8r's idea of using some 1mm washers to determine the minimum size spacer you'll need. Works better if you have studs rather than bolts though.

Thanks guys! I appreciate all the info.
I'm not as technically able as I should be.
I'm hoping the OEM CSL (not ZHP) will fit with no spacers. I'm tracking a few different cars so this won't seem a lot of use.
