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 models) 1. 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.
Original Cayman GT4 and Boxster Spyder drop links, both front and rear, work perfectly with CMS Performance Sway Bars; no need to replace them.
Base, S, GTS models require CMS front drop links (choose from the options above). 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.
