... here's the lowdown.
The top of the struts are already sufficiently strong, because they are part of the unibody. Having said that, I did install a rear top strut brace many years ago, together with a top front strut brace and they did eliminate a little squeaking when the car went up (sideways) on a ramp or driveway.
Both of those braces are still on my car, because they do help tie things down a bit and the car flexes less.
The TechnoBrace however does tie together the bottom end of the rear suspension, which is only held in place by the aluminum skid plate, which can easily flex.
When I started doing R&D on the TechnoBrace I measured deflection of up to 0.6 mm between the bottom of the rear struts.
During daily driving or straight-line driving, such as highway, you will not notice a difference with or without it.
Where it shines is at the AX track or any time where you are cornering hard under power. It lowers my times about 1 second on a 60 second course.
The reason why it works is because it maintains your car's rear camber setting throughout the turn, allowing for maximum tire contact with the road and eliminating what's known as axle hopping.
This type of brace was also very common on the earlier Miatas until Mazda decided to supply them installed from the factory.
Hope this helps.
Feel free to contact me directly for any additional information.
