Engine mounts, also called motor mounts, are critical components of your Porsche, securing the engine to the chassis and absorbing vibrations during operation. Traditionally, rubber has been the go-to material for these mounts, but polyurethane is gaining popularity due to its enhanced performance and durability compared to rubber.
Polyurethane motor mounts excel at absorbing vibrations, ensuring a smoother and quieter ride, benefiting both driver and passengers. Although they are initially more expensive than rubber mounts, their longer lifespan makes them more cost-effective over time, reducing maintenance and replacement expenses.
In high-performance vehicles like Porsches, motor mounts face extreme stress, vibrations, heat, and pressure. Uprated polyurethane motor mounts provide additional benefits by limiting engine movement, enhancing engine stability during acceleration and gear shifts, and offering improved gear engagement, thus protecting gearboxes and shafts.
