If you want serious performance, handling, and traction when you're at the dragstrip, AutoX, or road racing; then you need a Spohn Performance fully adjustable torque arm, here's what it'll do:

• Attaches to the rear axle and controls rear end torque during acceleration, transferring this energy into the tires, increasing straight line traction
• Reduces nose-dive during braking
• Eliminates wheelhop
• Increases sidebite during corner exit acceleration
• Entire package is a complete bolt-in assembly using existing mounting points on the vehicle. No drilling or welding is required!
• Removes the torque arm pivot point from the rear of the transmission to the Spohn crossmember
• Changes the instantaneous center and leverage point from stock
• Provides adjustable pinion angle
