Just got the steering rack brace and clamp kit, and 6-point subframe installed last night. These were my first true upgrades to the car, and all I can is "Wow!" I have a 2003 Saab 9-3 Convertible and the cowl shake got pretty bad on rougher roads, train tracks, and ESPECIALLY when turning on rough terrain the steering wheel would almost feel floppy, the tires would "groove" with the pavement, and a lot of traction was lost. However, with these upgrades, the cowl shake is virtually gone, and my car feels MUCH more rigid, and I can do tighter turns now.
Installation took my friend and I about 3-4 hours for everything, including trying to figure out the instructions given, but the installation itself wasn't hard at all. It's basically unbolting old parts and putting the new (and MUCH sturdier) parts on with the exception of the 6-point subframe where you must rivet and essentially make 2 new holes for drilling. I would highly recommend getting a car ramp, and then jacking up the back as there is almost no clearance under the car.
Other than that, this was a fun, pretty much hassle-free installation.
