The billet aluminum mounting brackets have been formed to perfectly fit the contour of your 911's strut towers, making installation a breeze. These truss style brackets have been engineered in a way that makes this brace not only one of the lightest, but one of the strongest braces on the market today. There is absolutely no alignment alterations or drilling required for installation. Fits all 911/912/930's from 1966-89. Black in color, silver shown.
