Perrin Performance - 25MM REAR SWAY BAR ADJUSTABLE FOR 2004-07 STI
REAR SWAY BAR
The PERRIN 25mm Rear Sway Bar is the perfect choice for racers and enthusiasts alike
PERRIN Sway Bars incorporate multiple end link mounting holes which allow the installer to custom tailor their driving experience. This PERRIN Sway Bar increases stiffness by a minimum of 85% over stock and adjusting the end link mounting position on this sway bar can increase that stiffness to as much at 300% over stock.
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.
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.
PERRIN Stout Mounts are overbuilt to handle the added stiffness of upgraded sway bars. From auto cross to full rally, you will never have to worry about these failing!
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.
