During high speed cornering, the strut towers of a vehicle’s chassis have a tendency to flex, making the vehicle less responsive. The Stack Performance “Stiffie” Strut Bar reduces the flexing of the strut towers by keeping the towers in a fixed position. This allows a vehicle turn-in to be sharper and an overall improved responsiveness of your vehicle.

The “Stiffie Strut Bar was engineered and designed to capture as many mounting points as possible which forces a solid, strong and stiff construction.

Unlike other aftermarket strut tower bars, The Stack Performance “Stiffie” Strut Bar has a unique design. The construction is very solid. A side by side comparison with other aftermarket bars shows the difference in strength and rigidity.
