Our kit replaces the original factory main bar in convertible models and adds it into the hardtop set-up. The sport bar is constructed of 1 1/2" x .120" wall tubing that is CNC formed. Our custom fitted bar adds rugged looks and safety to your vehicle and can be used to mount additional necessities into the vehicle such as a fire extinguisher or first aid kit. The rear main bar can be mounted independently or in conjunction with the complete front hoop assembly for a full cage enclosure. The CALMINI kit comes complete with all necessary pre-bent tubing, mounting and strength gussets, and complete hardware for the installation.
