Thank you. You have rated this product.

This PROGRESS Rear Anti-sway bar is a larger 22mm diameter, and features two-hole adjustable rate bar ends. This is a easy-to-bolt-on component that will dramatically improve handling capability and minimize the traction-robbing body 'lean' during cornering. This complete kit includes all necessary hardware including polyurethane bushings, TIG-welded reinforced bushing brackets and synthetic bushing grease.

Progress anti-sway 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 bars replace skinny OEM 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.

-Includes unique Progress mounting system and all necessary fasteners.

Progress Anti-sway bars are cold-formed in-house using our custom-built precision bending equipment. Both laser-cut and CNC bar ends are MIG welded in place using a precise fixture for an exact fit.

OEM 18mm sway bar rate = 334 lb/in.

Progress 22mm (soft) rate = 772 lb/in. (231%)

Progress 22mm (firm) rate = 1015 lb/in.(303%)

NOTE: We suggest starting on the 'soft' setting.

NOTE: These are the sway bar rates, NOT the wheel rates.

Size: 22mm

Adjustment Range: 2 hole

This system is designed for use with OEM end links.

Sway bar is powder coated metallic gray.

I received the Roadstersport II, and I wanted to compliment you guys on an awesome product. The Miata should have these on from the factory. They make a great sound, that is not obnoxious at all. The exhaust also installed seamlessly!!! I will buy all of my Miata stuff from you in the future. Thanks,

Brian, Thank you!!! We last spoke in November about some upgrades for my 2011 MX5 soft top. It has finally warmed up in NE Ohio and two relaxed weekends of wrenching on my car were well worth the effort. Installation of the RoadsterSport ceramic coated street header was straight forward and took under 8 hours, including a 40 minute test drive and cleanup of the garage! Combined with the RoadsterSport Q exhaust, the sound is fantastic and the increased torque, horsepower and performance make it a blast to drive. The addition of the Cobalt shock tower brace, Racing Beat sway bars, ILM front power train and X braces really enhanced the ride - minimal body roll, comfortable and very responsive. Your recommendations really helped transform the car from great to fantastic. Your research, product development and candid recommendations make you a standout in the industry. My only questions are - what's next on my list .... And how soon will my wife want the same upgrades on her 2012 PRHT ... Again, thank you!!! Charles G
