Description

BMW Z4 E85 Wind Deflector Mounts for my DIY Wind Deflector. I designed and printed these to fix my DIY perspex/acrylic wind deflector in place. I have included the 123d files in case others want to adapt. Please make sure you link and share any variants as remixes. The Hook has a slot to fit 2 M8 nuts inside. Use flat headed (Or countersunk) M8 bolts to attach in place as per pics. Screw Plate goes on the part of perspex that's on the inside of the car... it help hide any small cracks that may appear from drilling the mounting holes. The Hook should be obvious where it goes! It's designed to hook the roll bars when in place.
