Rear sway bar
 

So i have gone through the search, read up on as much info as i could on adding a rear sway bar to my Pursuit Gt...but i have also read on how its not entirely necessary seeing that the cars already come equipped with one.
The car will be running the road course this summer and i have lowering springs (ssc) but its also my daily driver...
Is it going to benefit adding a rear sway bar? or should i go ahead and replace both front and rear ?

It will benefit you to replace both actually. I would recommend the FE5 front sway bar found in any of the SS Supercharged or SS Turbocharged Cobalts, along with the OTTP Street Rear Bar.

x2 on the OTTP swaybar. Mine is on order and I can't wait (well and also for spring!). Just a question as I'm unfamiliar with the Pontiac suspensions for this platform. Doesn't the Pursuit GT have th FE5 swaybar from the factory?

no, it has the FE3 since it's the same as the 2.4 SS, or Sport model Cobalt.

Good to know. I thought there was a mid suspension between the FE1 and the FE5 just couldn't remember.
