Thanks guys. I looked at my car the other day and it looks like the sub box is about an inch higher than the strut towers in the rear. Looks like I have another reason to switch to two 10s

The car does have a rear sway bar, but it looks tiny. I might find a thicker gauge rod and see about bending it to match and swapping it out.

 

I would recommend doin lots of squats....and slowly go up in weights...lol
That would tighten up a rear end quickly!....

Just kidding....
My montes Z-34 suspension is super tight and I dont have any excessive body roll....

 

You could just swap your rear sway bar for a factory 06-07 SS rear sway bar. It's the same configuration but the SS uses a beefed up sway bar compared to the LT model.

 

Also how aggressive do you drive? Solid sway bar compared to hollow. BIG difference.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o:p></o:p>

i bought the gmpp rear sway bar for my 06 lt, havent installed it yet but looks nice, also have plans for bilsteins and lowering springs. that oughta do it!

 

I've got Bilsteins on mine paired with lowering springs, they're nice. Definitely recommend them.

 

Question about this, a bit late...

How hard is this to do, and did you order GM parts or aftermarket?

I've found this front struct tower brace:
1996 - 2006 W-Body | Strut Tower Braces | STB005 - Strut Tower Brace, Front | BMR Suspension - The Leader in High Performance Suspension & Chassis

But I cannot find a rear brace. Any reccomendations?

 

I used the stock brace on the front & rear ..Maybe after you get that brace you can see if it will work on the rear of your monte.? If not get a stock brace..

 

I have the ZZP front and rear strut braces. The rear brace is in between the amp rack and the sub box.

 

Found in another thread... that the front for the W-body fits the '06, and that the GM strut tower brace the same for front and back.

I ordered the Don Rome brackets, and the kit that comes with two stb's for around $120. Just have to go get a torque wrench.
