Best Sway Bars for the BRZ and GR86: 5 Top Picks Compared

The best sway bar upgrade for a BRZ or GR86 depends on which end of the car you are tuning: a Perrin 22mm front bar ($159.00) or FactionFab 22mm front bar ($343.00) sharpens turn-in, a Cusco 16mm hollow rear bar ($257.66) or H&R 18mm adjustable rear bar ($449.10) helps the rear rotate, and the aFe Control front and rear set ($545.00) does both ends in one matched package. Every pick below was verified active in our catalog today, and fitment spans both generations where the listing says so.

1. Perrin 22mm Front Adjustable Sway Bar — $159.00

Perrin [13-25 BRZ, 13-16 FR-S, 17-20 86, 22-25 GR86] Front Adjustable Sway Bar 22mm — $159.00. The value pick of this guide, and unusually broad: Perrin's listing covers the 2013–2025 BRZ, the FR-S and 86, and the 2022–2025 GR86. An adjustable front bar is the classic first chassis tweak on these cars — it flattens cornering without touching ride quality the way springs do.

2. Cusco 16mm Hollow Rear Sway Bar — $257.66

Cusco [13-16 FR-S, 13-20 BRZ, 17-20 86, 22-26 BRZ/GR86] Rear 16mm Sway Bar — $257.66. Cusco's hollow rear bar is listed for the first-generation cars and the 2022–2026 BRZ and GR86. A stiffer rear bar is how you ask the back of the car to follow the front more eagerly — the change drivers describe as the car rotating instead of pushing.

3. FactionFab 22mm Front Sway Bar — $343.00

FactionFab 13-22 BRZ / 13-16 FRS / 17-21 86 Front 22mm Sway Bar | 1.10239.1 — $343.00. FactionFab's 22mm front bar covers the 2013–2022 BRZ, FR-S and 86 range in its listing. A matching FactionFab 18mm rear bar is also listed at $235.00, so a matched FactionFab pair is easy to assemble if you prefer one brand at both ends.

4. H&R 18mm Adjustable Rear Sway Bar — $449.10

H&R [22-24 BRZ][22-24 GR86] 18mm Adjustable Rear Sway Bar - Black — $449.10. The second-generation specialist: H&R's adjustable 18mm rear bar is listed specifically for the 2022–2024 BRZ and GR86. Adjustability is the point — you can soften or stiffen the rear's contribution as your tire and alignment setup evolves.

5. aFe Control Front and Rear Sway Bar Set — $545.00

aFe Control [13-26 GR86/FR-S/BRZ] Front and Rear Sway Bar Set - Blue — $545.00. The do-both-ends option: aFe's set covers an enormous range — listed for the 2013–2026 GR86, FR-S and BRZ — and replaces front and rear bars as a matched pair. For a car still on both stock bars, this is the single-purchase answer.
