So I just bought a set of KW V2 coilovers for my e92 (P/N 15220032). They seem to be the same price EVERYWHERE so I snagged mine from ECS Tuning since they offer $150 in ECS gift cards (and I planned to buy a few more items from them anyway).
Part of what sold me on the KW?s over other brands is that they are supposed to be stainless steel. Living in the snow belt, I HATE rust. Anyway, for years I've seen people posting pics of their shiny new silver KW's. Well, I opened my box as soon as it was delivered (direct ship from KW in Germany) and noticed I have black painted/e-coated rear shock bodies. That's weird. Why would you coat stainless? (See pic #1) So, I inquired to ECS. Their product team confirmed that they are coated on the rear shocks, but that the bodies are still stainless. Looks like I missed that detail in the pictures. They show them black as well. (See pic #2) Just to appease my curiosity, I also contact KW. Their website shows silver rears. (See pic #3) Something must have changed, right? Well, their tech guy informed me that only the struts have stainless bodies and that the rear shocks are coated steel and have never been stainless. Huh?! Am I blind? Have I been missing this detail in all the product descriptions over the years? Does anyone here know what?s going on? Maybe some of our vendors? The guys at KW got pretty defensive and acted like I had no idea what I was talking about, so I don't want to waste anymore time with them. CLIFF NOTES: KW advertises their coilover kits as stainless steel. The V2 set that I just bought has painted rear shocks. The seller states they are still stainless underneath the paint. A rep from KW told me that they are NOT stainless on the rear, hence the paintin,g and that only the fronts are stainless. Does anyone else have any insight?

This is super confusing now.

Just a follow up on my investigation.
- ECS Tuning Rep states the rears are infact still stainless steel, but they do not know why they are now painted. - KW Rep #1 states the rears are NOT stainless steel, thus the need for coating (and that only the fronts are stainless). - KW Rep #2 states the same as ECS. The rears are still stainless steel, just that KW only offers them coated for some unknown reason. So, I'm still somewhat confused, but 2 of 3 stating they are still stainless underneath the coating makes me feel a little better. Anyone else have any info that might help clear this up?

Not necessarily true as some stainless steels are ferrous.

Very good points.
I checked... front struts are not magnetic, rear shocks are magnetic.
