Coming from a Z71 pickup, I'm finding the ride in my 2005 base Impala to be a bit on the sloshy side Laughing

What are you guys doing to tighten this up? Is there a recommended kit?
I see they have front and rear sway bars for these. Is the SLP front/rear set worth the $329?

Looks like a front and rear STB (Strut Tower Brace) is a common modification.

Donrome's brackets? (http://drcustomparts.com/STBBars.htm)

GMPP suspension parts?

Anyone using any of these components? Thoughts?

Other solutions?

Thanks! Cool

I'd recommend starting out with the GMPP handling kit. It includes thicker sway bars and a rear strut tower brace. You would need the Don Rome brackets to install the STB. I have this kit in my 2000 LS, and it really improved up the handling, but is still very comfortable. It used to come with boxed trailing arms, which are also a noticable improvement over the stock stamped units, but you can get boxed dorman trailing arms for cheap from rockauto.

After that, to get more of a stiff ride you will want aftermarket springs and struts.

Looks like the Donald Rome brackets are $45/set. What is his story anyway? Web site is very low budget. Fabricator? Have his own store/shop?

GM parts:

12498642 - W-car Heavy Duty Rear Stabalizer Bar Package
12498648 - W-car Strut Tower Brace Package
12498643 - W-car Heavy Duty Front Stabalizer Bar

Anyone have the part number(s) for the GMPP solid tubular trailing arms?

Just found the PN for the entire handling kit - Thanks patyson Smile

Don't worry about the lack of pizazz on Don's site, his products are top notch. I've got a set of his brackets in my car and love them.

The GMPP tubular trailing arms have been discontinued, but some people have used the boxed trailing arms from newer Impalas with good results. Anything is better than the terrible stamped steel trailing arms on there now.

I have Don's rear brackets as well. Great quality and no problems with his service. For trailing arms, the best bang/buck in my opinion are dorman's boxed trailing arms from rockauto at $12 a piece. Dorman part #905501.

How many miles are on the struts? They may also be making a big contribution to your sloppy ride.

No idea on the struts.

You can sometimes find the strut tower braces in junkyards for next to nothing. They came stock on 3.8 base Imps as well as others. Maybe even the Grand Prixs?

Impalas, Montes, and Regals.

Nay on the Grand Prix. Unsure about century's and intrigue's.

Good tip. A little clean up and powdercoating can do the trick!

If you go, keep your eye out for a police Impala, as they have the complete gmpp handling kit.
