Can anyone confirm if the SLs have sensors on all 4 wheels or only 2, 1 on the front and one on the rear? Thanks.

Thanks. That's what I thought but some of the vendors are selling them in 4 packs. I guess I'll put it up on a lift and confirm. Getting ready to swap the pads for carbon ceramics and will also install new sensors.

I assume you're already seeing the "visit brake workshop" alert; otherwise just reuse the sensors you have (even if you have the alert likely only one has grounded). I was quoted $10.43 front and $9.47 rear but didn't need either as neither was grounded out.

Also I'm curious how the will stack up against the Porterfield AP1670 R4S and AP1689 R4S (Carbon Kevlar metallic blend), which cost me about $300 all around and have virtually no dust and stop great.

Contacted Power Stop customer service and found out they provide new sensors with their pad kits along with all of the other hardware and lubricant. I will post an update after I install them and drive for a few hundred miles.

mbusa website lists wear sensors at all 4 wheels.
