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
• Engineered specifically for the Porsche 981 and 718 chassis

Adjustable Sway Bar Kit Includes the Following:

• Front and rear five-way-adjustable sway bars w/ forged ends
• OEM Porsche bushings custom-machined to our specifications
• OEM Porsche front drop link set, customized to our specification (required for Base, S, GTS)

• Position: Front stabilizer bar (anti-roll bar) – chassis-mounted bushing.
•  Function: Reduces body roll, stabilizes front axle movement, and helps maintain proper suspension balance.

Worn stabilizer bushes can cause:
• Clunking or knocking noises over bumps
• Increased body roll or vague steering response
• Misalignment of the stabilizer bar
• Uneven tyre wear or degraded road feel

Replacing with a Genuine Porsche bushing restores correct bar positioning, suspension tightness and the crisp handling expected from a 911 / 981 / 982.
