If you're only going to do one thing to your ND, this is what it should be. Tame that body roll! Speed up transitions! Fine-tune your handling balance to your preference!
Sway bars are used to make your car corner flatter and react faster by keeping the body (and all the weight) under control. Ours are set up for neutral handling and are adjustable so you can tailor the handling of your Miata to your own driving style.
Our swaybars are hot formed from 4140 CrMo spring steel. This means they're stronger than the cold-formed bars found elsewhere. We've designed them to keep the same handling balance as your stock sways, but they have three settings in the front and three in the rear for fine-tuning.
The front bar is a tubular design with 1.125" diameter and 0.188" wall thickness, while the rear is a solid 0.625". Both have three adjustment holes and include polyurethane bushings, brackets and grease. The front bar also includes stoppers to keep it from sliding side to side.
Also available as individual front and rear bars if necessary.
There are some kits on the market that reinforce the rear sway bar mounting brackets. We haven't figured out why, as they're a decently strong part that has shown no weakness either in our testing or during the MX5 Global Cup development. Our sway bar manufacturer and design partner can't come up with a reason to reinforce them either. While it may be possible to show on a test bench that these parts deform under hard use, what really matters is how the bars perform in testing. And in our testing, they perform very nicely.
