ProParts USA Swaybar Dyno Results for the ND & NC Miata / MX-5, RX-8 and FD RX-7

These modular sway bar kits are designed to give a racer/enthusiast  the most options. Because of these options, the sway bar kit can work for a variety of applications, street, auto-x, road racing and more. To start with, there are multiple torsion bar wall thicknesses to choice from. Not everyone likes the same thing. Some might like higher springs and less sway bar or vice versa. Some cars work better with more sway bar and some with less. On top of that, the billet aluminum arms have an adjustable slots to further fine tune the balance of your car. The slotted arms allow you to make adjustments by loosening the through bolt and siding the link assembly. In our racing experience, this is more efficient verses removing the through bolt and choosing another hole. The end-links use a 7/16 spherical rod ends and have left and right threads to make sway bar preload easier to set. If you are using scales to corner weight your car, this is important. The bushings that wrap around the sway bar torsion are urethane and allow just enough compliance not bind up as the chassis flexes. The urethane bushing are captured by a heavy duty 3/16 bracket for added strength.
