I installed sway bars on my 2008 Mazdaspeed 3 so when I purchased my MX 5 I knew this would be my first upgrade. Big improvement versus the stock rear sway bar. The OEM basically looks like a toothpick. Looking forward to installing a front sway bar but happy now with how the rear is improved.
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.
