THE SINGLE BEST MODIFICATION YOU CAN MAKE TO THE PORSCHE 981
Competition Motorsport has engineered the perfect replacement sway bars for the Porsche 981 Cayman or Boxster (GT4/Spyder, GTS, S, or base model). Through countless hours of testing, through thousands of street/highway miles and hundreds of laps at racetracks around the country, the CMS Performance Sway Bars perform flawlessly and greatly improve the handling and tunability of the Porsche 981. With five holes of adjustment both front and rear, these large-diameter bars can adjust from slightly softer than stock to much stiffer, giving you a wide range within which to tune your car's handling depending on the road or track you're tackling.
Included are OEM Porsche sway bar bushings, precision-machined for worry-free fitment, OEM quality, and a noise-free installation. CMS sway bars are engineered and manufactured in the USA with drop-forged ends for incredible strength and performance.
CMS Performance Sway Bars for the 981 have diameters of 31.8mm (front) and 25.4mm (rear), 30% larger than the already-uprated OEM Cayman GT4 bars! This creates a stronger, stiffer platform from which to work for all the 981 variants. Additionally, the range of adjustment of each bar goes from 1% softer than stock to 50% stiffer. This gives you a huge range of relative front-to-rear spring rate to fine-tune the handling of your Porsche.
We powder coat each sway bar for ultra-durability. Choose from four stock colors (Basalt black, Guards red, Racing yellow, GT silver). Or we will coat them in any of our thousands of custom colors for only $100!
With CMS Sway Bars you can balance your front-to-rear handling to suit any road or track.
Designed and manufactured in the USA using all US components, developed specifically for the Porsche 981, including the track-ready GT4.
