GTS offers a Triangulated 4 Link. This type of 4 link design is a proven design and is popular with drag races, street/strip machines and even pro-touring/road racers.
A triangulated 4 link is a rear suspension that uses 4 bars, also known as links, to hold the rear axle in place under the car and help the rear end articulate in a way to gain traction. It uses 2 bars under the rear axle that mount forward of the rear axle on the frame rails. There are then 2 upper links mounted to a cross member at an angle toward the center line of the car, which is where the term triangulated comes from. By triangulating the upper bars, this allows the bars to keep the rear axle centered in the vehicle, thus eliminating the need for a panhard or watts bar.
