If you drive a gsr you dont have to worry about the front sway bar, same as the itr already. Comptech says that there is no need for a rear strut tower brace in our cars. If you get an ITR rear sway bar, then you need some kind of reinforcement. There is a beaks kit, or the BSQ kit. A pricey, but better option might be the comptech rear sway/tie combo.
