This is a top mounting tow hook that installs onto the shock tower, as now found in many Japan GT cars.
Most tow hooks install onto the front subframe, which is not always accessible, especially in emergency times if the car needs to be pulled and the front subframe is damaged or inaccessible.
This is a highly unique item that Nagisa Auto originally created for their record breaking R34 GTR super lap car.
You will need to cut your hood to install this item.
Check with your local racing organizations rule book prior to installation and use at race events.
