I went with the str.t and I'm really happy with them, but only bought them because I couldn't afford the sports at this time. Eventually I'll just sell the str.t's and get the yellows.

BUT, even with the str.t's the difference is night and day. It's a different car now, comfortable, sure-footed, especially on rough roads.

 

That is a pretty typical response from folks who upgraded. I've had people in my cars that thought theirs were great, for about a mile and by the time we get back they tend to order new dampers. It's a big difference, and frankly it should be the FIRST mod to the suspension of an S197 (and most all other cars).
