It is a newly conceived reinforcement part that reinforces the floor by binding the right and the left sides of the rear floor with a steel pipe. It produces the effect close to the tower bar without almost sacrificing the ease of use of the luggage room. It concurrently uses the high-intensity bolt, etc. of the seat for installation, and won’t cause any annoying burden on the body, either. We particularly recommend that it be installed together with the front strut tower bar.
