For those of you who are wondering how these braces affect your car, these bars greatly increase the agility, performance, and stiffness of the Mazdaspeed3. Turns are now taken effortlessly without lean or chassis movement. Steering response is dramatically increased and the driver feels more at one with their car. These replacement bars also reduce the weight of the car even when removing existing braces and replacing them with the new GT Spec ones. In autocross before and after there were extensive turn in and power out improvements increasing lap times. The installation process is extremely easy. All you need are socket sets (12mm, 14mm, 17mm, 19mm, 21mm), a flathead screwdriver, an 8mm allen key and a tourque wrench. Here are some pictures of the install of every bar GT Spec has available for the 2007-2009 MS3:
