Progress MX5 anti-roll bars dramatically improve handling. How? They minimize the traction-robbing body "lean" that rolls part of the outside tires off the pavement. Our Sport-tuned Anti-roll MX5 Miata Sway bars replace skinny OEM Miata Sway bars and rubber bushings with larger diameter (stiffer) alloy steel bars and polyurethane bushings.
More roll stiffness means less body "lean", and the tires stay flatter on the pavement (larger contact patches). The result is more grip and added driver control!
-Less body roll means more traction, faster cornering speeds, and increased driver confidence.
-Polyurethane bushings produce crisp response on turn-in. Progress Anti-roll bars are cold-formed in-house using custom-built precision bending equipment. Laser-cut and CNC bar ends are MIG welded in place using a precise fixture for an exact fit that is more durable than alternatives used by some other choices.
-Size:REAR 16 mm SOLID
-Adjustment Range: Rear 2 holes
-All sway bars are powdercoated metallic gray.
-One year limited warranty.
Brian's APPLICATION NOTES: Lots of testing results in a rather unique rear setup that boxes the factory mount because the factory mount is essentially open, with a lot of flex. Initially we thought of boxing the D clips but once we found the actual source of the flex we tested the boxing and that proved a lot more effective at actually giving us the benefit of the extra bar stiffness compared to stock bar, something most choices overlook. The result is that our rear 16mm is more effective and linear in rate than most bars, even those that are even thicker.
