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. Flyin' Miata's are set up for neutral handling and are adjustable so you can tailor the handling of your Miata to your own driving style.
These sway bars are hot formed from 4140 CrMo spring steel. This means they're stronger than the cold-formed bars found elsewhere. They're designed to keep the same handling balance as your stock sways but 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.
