Lucerne Strut Tower Brace - Installed with parts list.

[2007LucerneCXL]

The STB is installed on a 2007 3.8L. These are available from Pontiacs see the link below for the GM part#, these show up on Ebay $50-70.
Pontiac Bonneville - H SHEET METAL/FRONT END > EPC Online > Nemiga.com

Parts needed
#21 - 4 needed
#69 - 1 needed
#70 - 6 needed
#71 - 2 needed LH & RH

See photos on clearance, I did try a mock up with the engine cover and it appeared that it would clear. This is a perfect match and all points line up, simply remove strut bolts, line up mounts, use new strut bolts loose, line up center and install bolts loose and once every thing is in tighten to spec. Extremely easy upgrade to tighten up the Lucerne.

Think it would fit a 3.9??

Have you noticed a difference in handling through curves?

 

[2007LucerneCXL]

Nothing I would say earth shattering but feels less wandering, still looking for larger sway bars from other GM models that will fit.

I would think it should, however I am not familiar with the height of the power steering pump which I'll assume is close to the same as the 3.8 alternator as everything still needs to fit under the hood. I also should note that I am not running with the engine beauty cover so that is something I can't say if it would be a issue and I wrap the STB in the mesh wire loom material as it appeared it was slightly pressing against the hood blanket, very small scuff on the blanket.

What diameter are the current bars?

 

[2007LucerneCXL]

Never measured them, but the GM part number for the 07 it's the same for soft and firm ride, I think I even saw it listed for a PA but don't hold me to that. Unfortunately it somewhat follows the same way that they are listing the struts as the same one is for the soft and firm ride. The only one that I found was for the 09 up Super that has a description change "Sport suspension. Lucerne. With super" which may be slightly larger and stiffer. They have one on Ebay new for $100 so I may just roll the dice and see what shows up, worse it's new and may firm it up.

They are ZZP, as to what real difference they were part of everything else dumped in, intake runner, exhaust power logs, crossover, high lift rockers. But I had a coil on the Lesabre that was flaky and the Lucerne coils got recycled so instead of getting a coil for the Lesabre I just got the ZZP for the Lucerne as a option.
