Installation Difficulty
Over time the factory thrust arm bushings on your 996 or Boxster break down, allowing deflection that introduces vague, imprecise handling and uneven tire wear. Rennline’s HD thrust arm bushing replaces the soft factory rubber with a firmer 85-durometer (shore) bushing that restores steering precision and control while keeping street-friendly ride quality.
