I made a small jig out of MDF so I could make a pair of wire arches for the front wheels. This would let me see how the arches will look against the bonnet lines. Rolled the 8mm wire to the required diameter which gives a 40mm clearance between the tyre and the top and the arch and the overhang is 16mm.
Next job was to mount the radiator which is a Z3 BMW (M spec). I machined a couple of cups to hold the lower rubbers which bolt into the lower plates. The top bracket is 15mm box with two 90 degree flat bars welded to it, these slot into the top rubbers.
