Hallibrand Wheels
The wheels dad ran were Halibran wheels that were custom from Hallibrand for Ed Zink for the MK III/Z4 car. As you can see on this picture of a MKIII/Z4 although at an angle the wheel . The wheel has a massive center hub.
The Zink petite MK II got the same treatment but Joe Virog did it a little differently. Both from and rear wheel had the center hub machined out leaving about 3/4 of an inch. This was then sandwiched with a steel face place to support the wheel.
One of the fronts
Unfortunately this one is cracked due to a shunt but I have acquired two new front rims as seen above the yellow painted rim. They are in need of machining to fit the Sunbeam Alpine hubs. Still usable for show but not to drive on.
Will probably get other wheels to protect these as they are irreplaceable.
