I have the heavier GVW Bilsteins that Bob Wagner refered to. They have been on for approx. 7 months and I love them!! They are a little stiffer than the factory, but the big difference is that they actually work like a shock should, especially on a rough gravel road, like the 35 miles out to the glacier. I had the Ranchos 9000 on my 98. 5 and the Bilsteins are far better on performance and the difference in quality is huge.
