Custom front bar from somebody like Robinson Racing in Atlanta and NO rear bar works the best for me in my ITS S14. I went through every "bolt-on" bar available last year to try them and ended up with above mentioned. Have thought of maybe trying a modified stock rear bar with my current set up but it really handles well now, I just like to tinker for that next tenth of a second... Call Barry at Robinson Racing at 770-888-1510, he'll hook you up.
