Anti-Roll Bars (ARB’s) play an important role in a vehicle’s suspension system, helping to reduce body roll by transferring cornering load from one side of a vehicle to the other.
Often mounted to the vehicle’s chassis with rubber bushes, these bushes ensure the bar works as intended. To prevent the anti-roll bar from moving laterally within its mounts when turning, OE manufacturers will either bond the bushes to the bar, add dead-stops to the bar itself, or rely solely on the clamping pressure of the rubber.
But what happens when those bushes wear and need to be replaced? Often anti-roll bars with bonded bushes come as a costly complete assembly, so the alternative is to fit a more cost-effective unbonded polyurethane replacement, like the many we offer.
In most cases, friction from the bush will prevent any side-to-side bar movement. Still, when turning aggressively or cornering at higher speeds, a laterally shifting anti-roll bar decreases the efficiency and effectiveness of the bar, changing the dynamics of your suspension system in unpredictable ways. It also poses the risk of the bar fouling on other areas of the vehicle or suspension system.

The Best Suspension Mod Available for the Porsche 981 and 718
Through extensive research and track testing, CMS has engineered the perfect replacement sway bars for the Porsche 981 & 718 Cayman/Boxster (all model) Our engineers took hundreds of laps at racetracks from Road America to COTA, Mid Ohio to High Plains, along with thousands of miles on the street. All to confirm the CMS Performance Sway Bars transform the handling of the Porsche while maintaining the car's everyday driveability and reliability.
Tuned to work with your Porsche's OEM struts and springs (both standard and PASM), the CMS Sway Bars are the best handling improvement you can make to your 981. Based on the sway bars of the GT4, the CMS Performance Sway Bars have five holes of adjustment both front and rear, giving you an unprecedented range within which to tune your car's handling depending on the road or track you're tackling.
Larger Diameter Plus Fine-Tuning Your Porsche's Handling
With larger diameters than the OEM GT4 bars, the CMS Performance Adjustable Sway Bars can be adjusted from slightly softer than stock to substantially stiffer. This lets you fine-tune handling balance from understeer to neutral to oversteer with simple hand tools.
Included are OEM Porsche sway bar bushings, precision-machined for the slightly larger bars, giving you worry-free fitment, OEM quality, and a noise-free installation. CMS Performance Sway Bars are engineered and manufactured in the USA with drop-forged ends for high strength and performance.
Base, S, GTS models have CMS front drop links. These are OEM Porsche front links customized to fit the CMS front sway bar. Your original rear drop links do not need to be replaced.
CMS Performance Adjustable Sway Bars Details:
- Diameters of 31.8mm (front) and 25.4mm (rear), 30% larger than the OEM 981 Cayman GT4 bars
- Adjustment of each bar goes from 1% softer than stock to 50% stiffer.
- Powder-coated Black, Red, or Silver for long life and great looks
- Designed and manufactured in the USA using all US components
