Yes it would bring back the push the original car had. The degree of oversteer and understeer depends on the front vs rear sway bar. I have the rear progress tech sway bar and it has caused my car to almost oversteer in some cases, which is what I like. Understeer ("pushing") is generally safer, but will interfere with good handling when you push the car hard (and know what you're doing). It all depends on what YOU want for YOUR car, there is no "right answer" for everyone on the understeer vs oversteer issue. Most front wheel drive cars understeer pretty heavily from the factory.

There was a post on this forum somewhere from Hib Halverson that did a real good job of describing the pluses and minuses of adding a rear sway bar and changing the handling balance.

The HHR is NOT going to oversteer without some major weight transferring ,brake input ,or lifting on the throttle mid corner sway bar or not.

 

That link does point out some of the reasons I decided not to get a rear bar.
I had one on a previous car, and the way it "skipped" around typical high speed corners was just plain scary. Would be a different story on a nice smooth racetrack though.

 

I finally installed my Progress Tech's rear bar. Now mind you, I dont drive my 08 2LT like its a Porsche. What I have noticed is getting on the freeway, making spirited lane changes, etc are noticeably more controlled now. The car doesnt lean as much. Also, I thought by tying the rear control arms would make it more clunky going over bumps. It's just the opposite. Im happy with my results.

 

You have found a "nice smooth racetrack" Nascar & F1 is looking for one

 

I put mine on yesterday, it is a noticeable difference it is still very balanced at the limit they should have put this on stock.

 

Anything with a solid beam axle is going to skip, with or without a sway bar.

My other FWD cars with solid/beam axles did.

 

Wow! Hib Halverson's article above, is awesome! Well done! That said, my plans are for; Eibach Pro Kit 1" front, 1.6" rear drop, KYB struts and shocks, Eibach 25mm rear swaybar, on top of 18/45/225 Continetal Extreme Contacts, Enkei wheels with a 42mm offset. I may change the wheels to stocks SS issue if I can find the "right" wheels (Enkei is out of stock). From what I have heard, this should pretty closely approximate the SS suspension, maybe a tad stiffer. I love this group!

 

OK, so I have a dumb question. I've read this whole thread, and I still not sure.
Is the rear stock anti-sway bar on 2LT, just a larger/thicker cross member stiffener (inside the "V" shaped piece with holes)?

The aftermarket anti sway bars clearly are an additional piece.

Is there a way to tell just by looking at the two rear axles? i.e. comparing a 2LT to a 1LT or LS?

Thanks!
