The shape is derivative of BBS E50, E55 model. The dimensions were made to fit my requirement for mounting 13″ tire and some other small changes were made. The first casting will be with 4×98 bolt patter, later I will cast some with a single nut option. The whole model is scaled up by 1.5% to account for the shrinkage after the mold cools down. The part will be heat treated and then machined. Special threaded inserts will be pressed for the hardware.
