Our BEST MX5 Sways! These Front and Rear PROGRESS MX5 Miata sway bars were developed on our own 2016 Project MX5 with all our racers here driving the car at the limit at local SCCA events to perfect the balance and test the bars at the limit. A perfect match for our Progress Springs to make your MX5 corner flat and stable through the most challenging turns!
Grassroots MotorSports Magazine picked these same sways for their Project ND, and concluded: "Our MX5 exhibited much less body roll. It felt better from behind the wheel. It looked better too, as our sports car wasn't trying to corner on the door handles. It certainly felt better, but what did the stopwatch say? The new anti-roll bars shaved our average lap time by 1.34 seconds." December 2016 Issue.
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!andnbsp;
-Less body roll means more traction, faster cornering speeds, and increased driver confidence.andnbsp;
-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.

BRIAN'S APPLICATION NOTES. Our Endlinks recommended to properly reach all the front bar holes. With these bars the ND Miata is so much more flat and stable...and a blast to drive on freeway on-ramps and mountain roads! These bars are finished off MUCH nicer than most choices, in some ways that will not be obvious from the little photos. Perhaps the most obvious difference between these bars and any other brand is the triangle shaped extra brackets you see in the pictures. If you look at the factory rear sway mounts the purpose will be immediately clear, because you will see that not all four of the factory rear mount corners are actually connected/supported. It brings back memories of what Mazda did with the NA/NB front sway mounts, where failure of the factory mount became so common that we had to offer a complete replacement mount (and Racing Beat offered 'blocks and bolts' for that generation to reinforce the factory mount to avoid it breaking). Very similar here, because the factory rear ND sway mount is not actually connected all four corners we provide the brackets that fully box the mount. We found solid .75 bar at the rear performed SOFTER than .62 bar with fully boxing the mounts. First picture below is the factory mount not supported on one side, and then second picture showing our bracket in place that fills the gap to fully box the mounts for long term strength and reliability.
SETTNGS: I strongly caution and suggest a more forgiving starting position such as middle or tightest position front (tightest is closest to center of bar) and the less tight rear setting (hole nearest bar ends) until you have some experience with the setup under controlled circumstances (such as an autocross event or big parking lot).
