Extreme TSC - Brand new old stock. This is a torque split controller allowing you to dial in torque to the front and up to 50:50 and initial increments. Fits R32/33/34 GTR and GTS4 models. This version allows you to remote mount the dial away from the main box.
Also has a 2wd switch suitable for the R32 GTR only.
This is a rare piece and no longer made. Ideal when paired with a Grid Digital IMU G sensor+Gyro sensor combo.
