I finally got the front 4-point brace installed. I cannot overstate how much more solid the car feels now, especially over bumps and rough pavement. If you think our chassis cannot be made stiffer, you are mistaken. The car now feels more like a stiffly sprung Mercedes and not a Z-car.
Again, unless you are tracking the car, it's not going to make you "faster", but these parts are definitely NOT placebos. They absolutely make a difference.
My cell phone is the suck at taking pics.
