:roll: any one have the ST Suspensions sway bars from hhr boutique, they are a helluva lot more expensive but they look worth it but i don't know.... http://hhrboutique.com/items/hhr-performance/hhr-suspension/st-suspensions-chevy-hhr-front-rear-sway-bar-set-52490-detail.htm

they sound a little pricey. what are you comparing them to.

Bought a Eibach rear sway bar from Autoanything,cost 140.00 to my door.Nice 1" bar (25mm) and installation was easy.Noticed a nice improvement in the handling.The ST bar is only 22mm.

The ST bar is 22mm solid, the Eibach bar is 25mm hollow....the Eibach bar is softer than the TTR, but stiffer than the ST 22mm

The ST front bar is 35% stiffer than the stock HHR bar.
