Reinforces the strut towers against deformation while adding valuable triangulation to the front end for sharper, more predictable handling. Designed to prevent “mushrooming” and other distortion caused by rough roads or stiff suspension setups, these plates help maintain consistent suspension geometry by reducing unwanted chassis flex. The result? A more stable, confidence-inspiring front end under load. Strut tower plates are engineered to sit perfectly flush against the towers. If they don’t, it’s a sign the towers have experienced some deformation. In minor cases, this can often be corrected using a block of wood and a hammer to carefully restore the mounting surface.
