Dark Knight GT said:Tell us more about your Bilstein + MM coil over combo. I'm getting ready to purchase me a set, and I'm just looking at what everyone's experience is with the Bisltein MM coil over combo.
I had the CO/Bils MM combo prior to what I have on now. The shop could never get the noise in the rear to go away. It was a loud noise that occurred when the rear end moved up/down or in an up/down angle. When we had my car up on the lift, you could see that the spring was grinding on the threaded spring mount and took off the last (top-most) 4 or so threads and ground them down flat.
When the shop took it off, one of the mechanics tried it on his car with the same result. Numerous calls to MM tech couldn't solve the problem. Now, many people had run the same setup with no problems so I can't tell you what the problem was. The shop replaced the CO setup with the H&R SS's, Bils, and panhard rod.
Now to the H&R SS/Bil combo. Between the two, there is IMO only a small difference in performance. The ride quality was the biggest improvement gain, IMO, in the using the CO setup. Felt a lot smoother and, for lack of a better term, "softer." Probably due to the lower spring rate and the moving of the shock/strut.
Is it worth the extra expense? IMO, no, unless you're going to see a lot of track/scca type duty. For a streetcar, they're not needed and you can get more parts for the price.
