Mazda RX-7 FC Room Bar / Rear Cross Bar
It is the bar linking both the B-Pillars within the passenger compartment. The effect of room bar is particularly obvious for a four-door sedan. This is because four-door sedan has a longer body than the hatch-back or coupe, the chassis is by nature weaker than the later two.

Material Specification & Design
Every materials used are carefully selected to ensure the best performance and safety. The brackets are made of 4mm to 5mm steel plates, while the hollow steel tubes and oval tubes are of 1.2mm to 1.6mm thickness. These materials are selected to ensure the bars are rigid and strong to maintain constant geometry at all times, yet safe enough to crumble during an impact for safety reason.
Steel vs Aluminum
Why we use Steel instead of Aluminum?
First, steel is stronger than aluminum for the same size and thickness. In order for aluminum alloys to be at least the same strength as steel, it has to be at least double the thickness (steel 4mm = aluminum 8mm). When that happens, weight saving is not so apparent anymore. Of course there are also exotic materials and alloys that can match the strengths of steel, but the cost are astronomically high and therefore not very cost effective to bring into mass production.One–Piece design strut bars are more rigid than Flexible design strut bars.
Therefore, they provide higher safety, comfort and stability under hard driving condition.Payment & Shipping
