Perfect fit and finish. Install was pretty easy, and the difference is considerable. If you take one look at the factory rear sway bar you can immediately see how thin and easily flexed it is, honestly I'm surprised it serves any function at all. I have a club model, and the stiffer sway bar pairs amazingly with the stiffer struts on my car. Much flatter through the corners, and the body roll is greatly diminished. I would recommend this to anyone looking to tighten up the rear end of their ND MX-5.
