Competition Motorsport is excited to announce our newest development for the Cayman GT4: CMS Performance adjustable sway bars. After over a year of development and testing -- on both the street and the race track -- we can say these are the single best modification you can make to your GT4, period. They are a must-have for track-day enthusiasts and spirited drivers.

The GT4 inherently understeers and is a bit sloppy in quick transitions. CMS Performance sway bars allow you to dial in precisely the handling you want for a given track or road, and dial out any slop in transitional response. Diameters of 31.8mm front and 25.4mm rear are 30% larger than the OEM sway bars, giving you a stiffer platform to work with. At the same time, each bar is fully adjustable from 1% softer than stock (!) to 50% stiffer than stock. The result is a huge range of handling tune-ability without making the car's overall ride and handling harsh or nervous.

Engineered and manufactured in the USA from ultra-high end domestic spring steel with drop-forged bar ends for high strength and performance. Powder coated in one of four stock colors (Basalt Black, Guards Red, Racing Yellow, or GT Silver), with powder-to-sample available (choose from thousands of custom colors).

Included in the kit are OEM Porsche GT4 sway bar bushings precision-machined to our specifications for a perfect fit, OEM quality and durability, and a quiet, squeak-free installation. They are designed -- and track-tested -- to use your OEM drop links. No need to buy noisy aftermarket links!

Nice work, CMS! An affordable mod with big effect. That equals great value.

CMS, Do you need a test mule?

kfmcmahon

me too!

Do you need new sway bar end links for this kit?

CMS

You use your oem links and we provide new oem bushings that have been machined to allow for the larger diameter.

We have tested the sway bars for the past year and have subjected them to thousands of track and street miles and are confident of the quality and performance and are looking forward to hearing feedback from those that have recently purchased them.

Thank you!

wow... that's a lot of adjustment points... I like! I am assuming 1% would be the full soft of these? Would you ever sell rears only? I am sure you see where I am going with this.

I'm assuming these will also fit a 981 CS?

Subd! Nice product!! Sorry for the noob question, do you need an alignment after replacing the sway bars?

Jamie@dundonmotorsports

Nope just to go drive it and see if the change was a benefit for laptimes/your liking...

mungee

do you have a landing on what the % difference means, i.e. Full hard front hole 2 on new Front bar etc? Be great to understand the base settings also so we can start from there.. PM SENT to you

CMS

You will NOT need an alignment after installing the new CMS sway bars. However, depending on your current alignment setting you might find that because the CMS sway bars neutralize the understeer of the car that you are much faster at the track and might want to increase your negative camber settings to account for the increased speed/tire wear.

CMS

Yes sir.

What material are the bushings made from? Thanks carl

CMS

They are new oem Porsche bushings that we machine to accommodate the larger bar diameter.
