Over the weekend I ran about 240 miles in some real twisty stuff. The car is buttoned down. A friend with a stock GTI and I swapped off for awhile and he was wowed with the combination of APR RSB's, DG springs, and The Unibrace trio. His car felt loose and soft in comparison. He immediately asked me what he needs to do to get his like mine. As noted earlier, start with the XB for best immediate impact and Stabilizing the "Box" structure, then add the UB to handle the chassis "Twist". The RB is icing on the cake controlling rear toe.
XB: Consider a shoe box with the end cut out of it...The box will be pretty flexy side to side. The hatch does little to stabilize that since it just latches and is hinged at the top...No real stability enhancing structure. Take the XB, tie the strut towers/Structure together, and the box gains stability. The flex is countered by the Triangulation of the Brace. Biggest win on this one.
UB: Take that same shoebox and twist it...Lottsa flex. Double the structure on the bottom and the potential flex is reduced. If you think the light Sheet metal tie bars do anything you're delusional. Adding to the bracing, spreading it over a wider area and the chassis twist is reduced. #2 on the Bracing hit list.
RB: Most of the cornering forces are transmitted through the lower control arms. While this area (stock) is pretty stiff, gusseted etc, Tieing those forces together and triangulating them to the rear subframe stiffens that whole area up. Flex is reduced and forces spread over more attachment points.
They each do something different, but in combination, make the car far stiffer than originally designed. A stiffer chassis allows the suspension to do it's job. Sway bar changes result in more precise control, and Spring rates are not absorbed as much by the chassis, but rather allowed to do what springs are supposed to do. Everything gets more precise. Some of these changes are wasted on the average street driver, but if you value precision and drive your car a little harder than average, you'll appreciate the differences.
The effect of these braces is immediately felt.

Hello Bruce
I would just like to let you know that during the course of this weekend, I was able to successfully install the XB, RB & UB. My first impression was the quality of the braces, very impressive, I was blown away with the accuracy of fitment; didn't even have to use a rubber mallet fitting the RB, it just fitted in there snugly by hand, amazing. Also, no clearance issues with my Ultimate Racing 3"TBE, actually had loads of room, also cleared the OEM sway bar ok, soon to be replaced by a SuperPro item, so not expecting any issues there either. RB Install time, approximately 30 mins.
I spent approximately 2.5 hrs installing the XB, not counting removal & replacing the rear seats; holes drilled easily using a 1/8th titanium bit to start, then switching to a titanium stepped bit & cutting fluid. Nutserts went in without a problem; job turned out very neat.
Left the UB till last, what can I say, fitting this is child's play, again, perfect fitment. Installed in approximately 15 mins & didn't need the spacer kit.
As has been stated many times before, the effect of these braces is immediately felt, the car feels tight especially with steering input, turn the wheel and the car reacts instantly, pointing into corners with a very direct feel. Also, I did notice that the car is quieter, no groaning rubbing noises from the doors; it really does feel like the whole car is tied together properly, handling overall is greatly improved, and this is all on OEM suspension!
Now I can't wait to feel it when I eventually upgrade the suspension haha.
Many thanks Bruce, I can happily say, that you have another satisfied customer.
Kind Regards,
G.B.
