Customer notes

The splitter material is ABS. The blade is secured with fabricated drop-down chassis brackets attached to the core support structure and externally reinforced by the Professional Awesome universal quick-release support system, featuring adjustable support rods anchored directly to the front bumper support.

The hand-formed aluminum air dam and splitter extensions mirror the exact contour of the original factory BMW E30 325is front valance profile. They are securely fastened with flush rivets and mechanical fasteners directly to the perimeter of the ABS splitter blade and bumper assembly for a rigid, aerodynamic seal.

Special thanks to my friend and amazing fabricator, Olof Olson (@Olof_501rf).
