Got the Cusco upper strut bar Friday and had it on since then. Initial impressions? Well after hitting some mini-twisities, it seems that in general any upper strut bar does actually help. I felt somewhere between a 10%-15% change in stiffness. I was able to take freeway entrances (the nice ones that twists around) at a faster speed with higher control. So definite improvement in entrance speed. Unfortunately, coming out of the turn, I still can't come out as fast...hopefully the CT sways will fix that ...and maybe some better gripping tires. The Cusco bar is from blxmjx.
