Perrin PSP-SUS-229 16MM Rear Sway Bar 13+ Toyota FR-S
Take your vehicles handling to the next level with PERRIN Performance sway bars. Upgrading your sway bar is the easiest way to improve vehicle handing. Sway bars increase roll resistance and modify vehicle balance. In general, adding a larger rear sway bar increases over steer, and adding a larger front sway bar increases under steer. Upgrade both front and rear sway bars to reduce body roll and tune vehicle balance to your preference.
16MM, 19MM, 22MM OR 25MM - PERRIN Performance sway bars come in four different sizes; 16mm, 19mm, 22mm and 25mm. We recommend the 16mm sway bar upgrade for drivers wanting a little sportier handling on stock or comparable tires. Driving enthusiast will enjoy the feel of a larger rear sway bar as it reduces under steer and in some cases adds over steer for drifting enthusiasts. When upgrading tires to grippier compounds and wider widths the larger sizes may be just what you are looking for. For a noticeable upgrade in stiffness while keeping close to OEM balance, combine our 19mm front Sway Bar with our 16mm rear sway bar. For a more aggressive upgrade try the 22mm front sway bar matched with the 19mm rear sway bar.
Adjustibility - PERRIN Performance sway bars incorporate multiple end link mounting holes which allow the installer to custom tailor your driving experience. This PERRIN sway bar increase stiffness by a minimum of 30% overstock. Adjusting the end link mounting position on this sway bar can increase that stiffness to as much at 729% over stock.
Centering Rings - PERRIN Performance sway bars feature centering rings that prevent sway bar movement in hard cornering. This keeps your sway bar centered and ready for the next corner.
Construction - PERRIN sway bars are CNC precision bent from solid 4130 chromoly steel. The entire bar is heavily powder coated to fight corrosion and give it a great red finish. We laser cut and MIG weld our bar ends for precise placement and superior strength. This type of bar end will never fail and offer you a lifetime of superior handling.
Bushings - All PERRIN sway bars include custom polyurethane bushings for a crisp response and better turn in. Special spiral cut pockets carved into the bushing surface extends the interval between re-greasing.
Wikipedia - A sway bar is an automobile suspension device. It connects opposite (left/right) wheels together through short lever arms linked by a torsion spring. A sway bar increases the suspension's roll stiffness—its resistance to roll in turns, independent of its spring rate in the vertical direction.
