As many of you know, I often feel that we are over charged for middle of the road parts for the S197 Mustangs. I recently purchased the Spohn/Hellwig rear sway bar for my car. It's a vast improvement over the stock piece and comes with very thorough installation instructions. I was worried about compatability with my BMR LCA relocation brackets. It is a tight fit but I had no clearance issues at all. It's heavy duty and my car lauches flat as a pancake now. The rear end shift when I hammer the throttle is gone and the car corners much better now even without the front swaybar that's been sitting in the garage closet for quite a while now. It's adjustable and I'm very pleased with it. At $261 delivered it's a nice deal on a very good part. You can save a few bucks by getting it from Summit. I purchased mine from the Spohn website.
