DC Sports Rear Strut Bar for 15-21 WRX/STi and 86/BRZ/GR86

DC Sports CS-2 Rear Strut Bar for WRX, BRZ, GR86 & FR-S – SKU: CSB1409

If you’re chasing real 2013 BRZ handling improvement or a no-BS 2015 WRX rear strut bar, this is it. The DC Sports CS-2 Rear Upper Strut Bar is a straightforward, proven chassis upgrade for the 2015–2021 Subaru WRX, 2013–2021 Subaru BRZ / Toyota GT86 / Scion FR-S, and the 2022+ Subaru BRZ and Toyota GR86. These cars already handle well out of the box, but tying the rear strut towers together adds noticeable difference. You’ll feel more stability, cleaner weight transfer, and better control when the pavement isn’t perfect.

By physically connecting the rear suspension pickup points, this DC Sports rear strut bar sharpens chassis balance, especially on rear-wheel-drive cars like the BRZ, 2022 GR86, and FR-S. A stiffer rear section can tame the sketchy, mid-corner wiggle and make oversteer more progressive instead of “all at once.” On the WRX, this DC Sports WRX handling upgrade keeps the back of the car from feeling loose in fast transitions and long sweepers. The result: more confidence when you really lean on it, whether you’re on a backroad, autocross, or at the track.

The CS-2 uses a rigid single-piece steel strut bar layout instead of a multi-piece aluminum setup with joints that can loosen over time. That one-piece design means fewer points of flex, no constant re-torquing, and long-term consistency, exactly what you want from a GR86 chassis stiffening or FRS rear strut bar upgrade. It’s a direct bolt-on using factory mounting points, so you’re not hacking up the car to get real gains. If you’re after a legit Subaru BRZ strut bar upgrade, Subaru FRS handling upgrade, STI rear strut bar alternative, or a 2022 GR86 rear strut bar that actually tightens the car up, the DC Sports CS-2 Rear Strut Bar is a solid piece to add to your suspension setup. We run this same DC Sports rear strut bar on our own cars for exactly that reason.
