This is the original 4C harness bar for the Alfa Romeo 4C. Developed in 2014 by our partners at Kansai Tuning Japan, Alfa9 Supply have been elemental in bringing this design to USA and global customers.

The ultralight design allows you to fit any brand of harness you like in your 4C, and gives you an instant improvement in lap times on the track with the more secure seating and driver retention.

It's minimal cabin intrusion leaves your arms and elbows plenty of room for steering. Crafted in Japan buy 4C enthusiasts, we are excited to offer this product here.

The bar itself is quickly removable by taking out 2-bolts if needed. It utilizes all factory mounting points with no drilling or cutting required in your Alfa Romeo 4C. The back plates are welded and serve as the backbone of the design, giving a sturdy and strong structure for the cross bar to mount to. The crossbar is mounted with 2 oversized m12 bolts rated at Din 10.9 , the back plate mounts using the 4 factory mounting points.

We recommend using this with the matching custom seat brackets and a pair of Recaro's or similar for top track performance. Email for delivery time on seat brackets, they are made on a per order basis.

Our bar solution allows retention of your Alfa OEM 3-point belts for use when driving on the street.

We have Sabelt, and Schroth belts for the 4C. The best fit and safest choice is to use a full 6 point harness and pass your belts through the shoulder slots on an FIA race seat. We recommend professional installation for harnesses.
