BMR Suspension designed the Ta001 for street performance, drag race, and handling applications. The heavy-duty design eliminated torque arm deflection, allowing power to transfer more efficiently to the tires. The torque arm allows for on-car pinion angle adjustability. The heavy-duty chrome-moly adjuster in the torque arm allows for on-car fine-tuning of pinion angle. The torque arm mounts in the factory mount with a 95-durometer polyurethane bushing. This transfers power efficiently, without huge increases in NVH. .
