SFI approved to SFI 4.1 specifications. B&M shields are manufactured of lightweight 6061-T6 aluminum alloy and include all necessary hardware. B&M units fit properly and are easier to remove and install. These units feature an added pem nut on the right side, allowing a dip stick tube to be bolted to the shield and additional clearance has been added to the cooler fitting location for installation of quick release fittings. The belly strap allows installation of a shifter cable bracket (two holes have been added to the strap for deep pans). These features have been made at the request of the racers and are SFI approved.
