I'm not an automotive engineer but I am a structural engineer and such bracing in the front trunk isn't my first choice in brace points. There's a couple other "elephants in the room" so to speak. I've had some good conversations with Goran Malmberg about his testing of torsional stiffness and tend to agree with his test results. I have Larry's bracing. There's two other really good locations to brace besides what Larry has: 1. The rear upper cross brace is useless and is a hinge where it needs to be stiff. There is significant twisting there. The Precision Proformance brace there helps. 2. The interior of the car twists the most. Rocker strengthening or full roll cage would help if done right but I would only do a roll cage in a race car where a helmet is worn. Also, to brace it right, the passenger seat would be useless. Just my two cents. Corey

If one actually was an engineer and analyzed this brace, it is utterly useless. It braces the shear wall construction already built into the upper A-Arm mounting points. Not much movement here with the factory job. Lots of help is needed down below to take the twist out of the lower A-Arm supports. Larry

Others seem to have managed to bolt it in, sitting very low in the trunk (less than an inch between brace and trunk floor). To be functional it should sit directly behind the upper shock mounts. Julian __________________________________________________________________

I am currently working on the front trunk area and I am trying to figure out the best way to mount the triangular upper brace (the part sold by Precision ProFormance). The mounting plates have four bolt holes but it looks like I would not be able to get bolts to work as they would conflict with the upper suspension mounting rail. I am thinking the best solution may be to plug weld those holes from the trunk side. Can anyone share their experience installing these plates?
Thank you,
John _______________________________________________
