Superpro Rear Sway Bar 18mm 3-Position Adjustable Scion FR-S / Toyota 86 / Subaru BRZ 13-20 | RC0015RZ-18

Stock sway bars give you one setting: whatever the factory decided works for the average driver. SuperPro's Roll Control sway bar changes that — it's 3-point adjustable, so you can dial in body roll and cornering response to match how you actually drive, from comfort-oriented street use to maximum roll control for track days, just by changing which hole the end link sits in.

Built from solid spring steel at 18mm diameter, this bar steps up stiffness over the factory unit at every setting — even the softest adjustment position is stiffer than stock. Moving from the soft to the hard setting takes you from a 27% increase over OE up to nearly double (98.9%) the stock bar's stiffness, giving you real range to tune the car's handling rather than a single fixed personality.

Note: Installation is a 2-hour job and SuperPro recommends a suspension specialist for the install. A rear wheel alignment is required after installation to keep the car tracking correctly.
