Thank you. You have rated this product.

Our BEST MX5 Sways! These Front and Rear PROGRESS MX5 Miata sway bars were developed on our own Forum 2012 PRHT Project Car! A perfect match for our Progress Springs to make your MX5 corner flat and stable through the most challenging turns!

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.

-Size: FRONT 28.5 mm (hollow bar; 6.35mm side-wall)andnbsp;
-Size: REAR 17.5 mm SOLID (both front and rear slightly stiffer than our Racing Beat choice)andnbsp;
-Adjustment Range: Front 3 holes, Rear 2 holesandnbsp;
-All sway bars are powdercoated metallic gray.andnbsp;
-One year limited warranty

BRIAN'S APPLICATION NOTES. These are SERIOUS! We had a number of customers wanting something more serious than our 1 inch front bar choices, more like the Hotchkis but without the $400+ price tag. So, we worked with Progress for more than a year on development, using our own 2012 PRHT as the development car. The resulting bars are a little stiffer than most choices (a little stiffer than our popular Racing Beat sways). My wife just loves the combination in our 2012, the car is wonderfully 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. One aspect of the higher quality in these bars is the brackets, which are MUCH more stout than the mounting bracket of any other sway bar choice we offer. The Brackets are heavily gusseted and WIDER to prevent flex and to give the wider bushings more coverage of the bar. Let's look at a picture of the Front Fully Gusseted and Cadmium plated Progress MX5 Sway Bar Brackets!

Think about the effect of those WIDER brackets! The extra width in the bracket means less stress for the bushings, which results in more longevity and consistency for many years of fun driving.


Now let's look at the rear brackets. Many of our other choices supply just a new bushing for the rear that has a bigger hole in it for the bigger bar and you recycle the factory tin brackets. That is a very efficient choice and helps keep cost low, but those thin tin factory rear brackets are just 'okay' and can easily be improved upon. Progress supplies rear brackets that are quite a bit more heavy duty than the factory.


Thus, these bars are just a notch more serious than our Racing Beat or Hotchkis or Eibach or any other MX5 Sways we sell. Note that both these bracket decisions make install slightly more involved. The fit of these beefier brackets front and rear is tighter than the stock brackets, and Progress supplies a spacer for the front that lifts the ABS bracket above the sway bar bracket because the bracket is so much wider that it would not otherwise install. These are small prices to pay for the extra stoutness and long term reliability of the installed result.

NOTE on Settings. My wife's 2012 has the bars set to middle position in the front, and tightest position rear. At that setting (and with our Progress Springs), I can throttle steer the car comfortably and it is a blast to slide around tight turns, but with those settings the car can be spun and my wife has spun it a few times at autocross events when really pushing much harder than folks should in the real world. Thus, 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).

Roadstersport II was a great purchase, easy install, and sounds great.
