The factory stamped steel strut bars are not up to par on the Scion FR-S and Subaru BRZ. We developed a strut tower bar system we call, Stiff Arm. The Stiff Arm bars are not only lighter then the factory bars but stronger providing a more rigid connection between the firewall and strut towers.
The Raceseng Stiff Arm bars are not only lighter then the factory bars but stronger providing a more rigid connection between the firewall and strut towers.
We utilized aluminum structural tubing that is 2X the wall thickness of the factory steel bars. Our tubing wall thickness is 1/8" thick while the factory bar is 1/16" thick!
The bar ends are intentionally designed to translate the load from the bar into the strut tower while maintaining a lightweight design. To achieve this we had to do extensive sculptural machining to create a minimum wall thickness throughout the bar end.
The union of the bar end and tubing is done through meticulous, high quality TIG welding. The physical bond created with this process creates an incredibly strong connection.
The Stiff Arms weigh .735 lbs while the stock arms weigh 1.043 lbs.
DIRECT BOLT ON
The Stiff Arms are a direct bolt on product, no modifications necessary. The arms come with high quality stainless steel hardware including socket head cap screws, nyloc nuts and washers.
