I would say the stance coils for you MDbizman are probably the right choice. A friend of mine wanted the same thing, superior handling and adjustable coils with a decent ride quality. He went with Stance. I assume the pro's but I'm not sure. All I know is he was ecstatic about driving his 240 after he installed, and got bit by the suspension mod bug
ended up installing aftermarket arms etc!
Moral of the story, they were what he was looking for and I assume you are looking for the same mayne.
