Thanks for the quick reply. This is good information for future use.
I installed the strut tower brace this morning and noticed the clearance was between 1/8 and 1/4 in. My son and I went fishing so I did not have a chance to road test until this afternoon. I just got back from a spirited test drive and there were no clearance problems that I noticed.
Man is this decent inexpensive mod. My front end really feels stable now even going into reverse camber turns. The sway and dip aspect of powering through a turn is gone from the front end. The rear end leaves a lot to be desired after this mod. Maybe someone that has done work to stiffen up the rear end will post what they did and we can build on the post in the same manner as this one. But I digress.
On to the pics.
Here is the way the strut tower brace is shipped from GM Parts.com. It arrived fine but there are scratches. A future mod may be to paint it the color of the car!!
Here is the strut tower brace installed.
If you are considering this mod I would tell you to go for it now. No telling how long GM will make this part and this is the last year for our beloved car. I do not think there will be any after market companies producing this part.
