  • Durability and reliability. BMW ZF / Getrag gearboxes have been successfully used in both amateur and professional motorsport for many years. They can hold a very high torque(some models 1000Nm+), while guaranteeing high reliability. They are ideal for SWAP in high-power cars intended for everyday use. (Daily)
