The upper strut brace stiffens the body a little bit (reduces flexing).
The lower strut brace is the one that eliminates axle hopping.
When I tested I was able to measure 1.15 mm deflection at the bottom of the rear suspension under very hard, under power cornering (Auto Cross conditions).
Between the upper strut braces there was negligible deflection, nevertheless, when I installed the upper brace, it eliminated small creaks in my car when entering driveways at an angle, so it stiffens the bodywork a bit.
I also found the same thing for the front upper struts. very little if any deflection, but they seem to stiffen the coachwork.
I personally have all three in my car.
Happy Boxstering,
Pedro
