davidke,
ur car has lotsa vibration after installing strut bar? (maybe u always tink she's a slut who likes to use huge vibrator??) LOL...
mine dun hv tis issue wor. just SLIGHTLY better steering feedback n a SLIGHTLY more responsive front end when cornering. but other than tat not much other effects. suspension firmness also no change at all when going tru bumps or uneven roads.
Vibration as in tremendous steering feedback. Hitting a stone, potholes, even squash an ant also can be feltnow

You don't feel it bcoz u didn't pay attention to your steering work BEFORE installing slut bar. My car is even more obvious bcoz my tayar already sagat, so now it sagat even more often

and by default, all cars are tuned to understeer (stiffer front end, softer rear end) as it's easier to control (for beginners) by just lifting off d throttle when d front tyres lose grip.
but for us slightly above beginner levels, we prefer a more balanced handling while cornering. thus d strenghtening of rear end is a common way to do it. but overdo it is a no-no as it will turn into a drift car n it's very dangerous to drive especially on wet roads!
my 2 cents. hope this helps.
Fren,
Torsion beam reinforcement will increase torsion rigidity, meaning less flex for our tofu beam liao. If less flex means both tayar akan stick on the ground. When that happened, you have more room to play with your front wheel's grip, either choose to continue attack corner kaw kaw until overspeed, or lift off understeer. It provide stability & secure the rear end during action.
It has more effect on BLM simply bcoz both our Sabby & GaGa share the same platform, whereas GaGa has a huge ass. With the extra weight BEHIND torsion beam, it will result in more lateral force when attacking corner compare to Sabby. Therefore installing torsion reinforcement in GaGa can actually help to reduce lateral force by strong torsion beam pulling the inner wheel down during corner.
However, my concern is not on the reinforcement torsion. The more I worried is on the chassis itself. Like kidmad said, if I everyday 24/7 go attack corner 100kmh, before the car I probably dai 1st. I feel my tofu beam is fine, I don't feel changing it. However, the rear lower bar is my concern. Our Sabby got a small tail, doesn't have strut at the back. On top of the cute ass is our pretty tail gate. Imagine during corner, where does all lateral force compressed into? That's right! Front the rear storage area all the way u to roof without anything to support!!! Chassis flex happened on the car before the torsion beam itself being bent.
My next target, rear lower bar. Instead of reinforce the tofu beam, might as well brace the member to increase chassis rigidity

These are my personal opinion, until I find my tofu beam not sufficient then I will reconsider to strenghten the beam

But probably before that will but sport abs & sport spring first
