I'd suggest buying the technica data book for your car but Brabus has modified your engine, either by boring and/or stroking. Please contact them for the proper piston specs.

I've overhauled my M180 220S engine with new pistons and the cyls are bored to the 1st oversize spec but the pistons are all slightly different sizes.

I still think you need to revert to bolts.
