Perrin 19mm Rear Sway Bar for the Scion FR-S / Subaru BRZ are made from solid steel using precision bending equipment. The entire bar is heavily powder coated to fight corrosion and give it that great red finish. We laser cut and MIG weld our bar ends for precise placement. This type of bar end will never fail and gives us greater precision over competitors. Utilizing this style of manufacturing process gives out bar better precision, higher quality and a fail free design. This is a huge improvement over the competition (some of our competitors simply smash their sway bar with a hammer to make the end. Creating a weak point and stressing the material. Improve handling and add adjustability with easy installation too!
