I personally don’t know of anyone else who has these on any vehicle which is what makes me a little hesitant. But I’m having a tough time seeing the downside. On the standard struts I measured and emailed the company to confirm that CSS-1125 is the right size. I was planning to do the AirLift Helper bags on my S, but this SumoSprings have me changing my mind.Nice. I've been looking at those as well. Do you know of any other owners who have installed them yet?
