Circling back to my idea out of no where about the front sway bar being too stiff contributing to "no feel", I was able to verify with Wepeel's post that the front bar contributes to 64% of the front roll stiffness on the BRZ. Perhaps some day I will get another BRZ so I can set it up for maximum feel and quite a bit more comfort than stock. I feel the 86 platform is balanced enough where no sway bars can be a good setup for spirited street driving unlike some FWD or MR cars.

I have driven my car with 6k/6k springs with and without front and rear say bars but I was using Eiback sways which are towards the stiffest sways available. I much preferred the without. Zero left <-> right crosstalk.
I have read of people complaining of too much under-steer and too much over-steer but this is the first time I have read of "too balanced".

Perhaps "too balanced" isnt' the proper description. How about too benign. Thanks for the feedback. I will definitely do the 6k/6k with good dampers when I it makes sense for me to get the brz as a 3rd car and breathe some life into a truly independent suspension.
