i do not really race around a lot but i do think the xB handles well w/ stock set up and i guess the extra stiffness would help in an emergency situation if i had to swerve suddenly or something...Eric said:You'd be better off going w/ front & rear sway bars rather than a rear sway bar and front strut bar... I only had the TRD rear sway bar & TRD springs on my tC & it made a world of difference. I loved driving that car! I've been told that the front strut bar is mostly for looks...
