I was browsing around on the Ultra-Racing Web Site and find this info. It shows very well how the strut bar works
For those who may not be aware of this would be good info for your reference. Base on this will list my thoughts on installing tower strut bars on the Koup.
The car is basically a metal frame attached to 4 suspension system which is then attached to the wheels.
Because of metal frames are in "bar" format instead of a single rigid piece of metal. It's easily subjected to twisting or body roll
Basically aftermarket strut bars are installed to react against such forces that act against the car body during corner, reduce body "twist" or roll.
Take note installing aftermarket coilovers reduces the rate at which the car's body rolls on its suspension springs, but not the effect of car body structure twisting.
The below picture from UR, shows the forces acting when the car corners at high-speed. The absorber mount flex inwards and upwards the car body.
The below pics shows the actual body roll conducted by UR mechanics
The diagram shows the UR guys install a tower bar - fig (1)
Saw it into half at the centre - fig (2)
Tilt car to simulate cornering - fig (3)
Measure body roll or twist - fig (4)
For my thoughts on the koup.
1. The shocks mounts are located very close to the fire-wall or the wall the separates the cabin from the car engine bay.
2. As a result the wall actually braces the mounts, acting like a strut bar bracing.
3. The bar design is critical for bracing, because all metal structure flex.
I have indicated 5 high stress pts on the joints of the strut bar. Too many blends and joint would reneder the bar weaker to brace the car metal frame.
These are just my own views which I share. You need to form your own views to determine if the mod is suitable for your style of driving, or the effectivness of the mod itself.
