Just got these on my 2008 328xi to replace the stock Continentals. Honestly wish I would have done this sooner. The Conti's are very hard and rough in comparison. Since the car has sport suspension I know I'll still feel every bump in the road, but at least now on the big potholes jar your teeth lose. And as anyone in Denver will attest there are plenty of potholes to test this out on. The ride is also a lot quieter now as well. I'll update again once I get more miles on it, but for now they seem great. Hats off to Southeast Auto for the great install job!
