Three piece wheel based on BBS E50/E55

Three piece BBS E50/E55 style wheel. This are wheels I designed for few of my projects. They are based on BBS E50/E55. It is scaled down to 13″ size and the mesh is modified slightly to fit the size change. There are two options. One with e central lock nut, suitable for track use and one with the standard bolt pattern 4×98. The back spacing is made to fit the standard and modified brakes. The ET and the width is adjustable via different size lip and barrels. The wheel will have a turbo fan covers to assist with brake cooling. All the patterns for the center section with single lock nut are printed and ready for casting. The model is simulated in casting software, before all the components are finalized. I am now doing the same for the lips and barrels, so I can cast all the parts and have a prototype in metal.
