I have the Boge struts on my BMW 733. They replaced the KONI's, which wore out and rode stiff, at lower speeds. The ride improvement was great as it is softer and makes the ride very supple, as good as my old Buick! They are not as good as KONI's, for 100mph back road drives, where the KONI's, are into their own. But, I don't drive that fast anymore, well I'm not supposed to...

I recommend them as a fine shock. I bought them at Bekkers Import Parts, and should be fine for your car. They are holding up OK. The BMW weighs about 3700 lbs. Hope this helps you.
