Really? Is the chassis already that stiff up the top?
The softest point will flex first. On a stock Euro, it won't flex much because of BODYROLL! Once you have a thicker rear sway bar and stiffer suspension, then you can feel the sharper steering response when you install the strut bar (same for the lower arm bar). I had the strut bar and lower arm bar installed when my car was stock and I couldn't feel any difference. After getting stiffer suspension, I can definitely say that the steering response is improved with the bars.
I suggest you do your suspension upgrade in this order.RSB(18mm),springs/shocks or coilovers,tower strut brace,lower arm bar.This then gives you the opportunity to evaluate each mod and see if you wish to go to the next stage.
