A strut tower brace is one of the simplest and most important modifications you can make to tighten up your Porsche's handling. Under hard cornering, the strut towers will invariably bend towards each other slightly, resulting in a change in camber angle. A strut tower brace virtually eliminates this flexing action and helps to keep the car flat during cornering, resulting in improved feel and more predictable handling. Rennline's bars are made from high-quality materials like aircraft aluminum and carbon fiber, and install easily with no drilling required.
