Anyone baffled by the complexity of this system (me for a start) and discouraged at the thought of using HCS in their FF design may be relieved to know that there are several brand new Voyager HCS wheel units available* - plus uprights for this system, with assembly jigs for the top and bottom 'wishbones'- although anyone capable of making a chassis could easily make their own wishbones. Cads (DXF files) for the geometry also available.

Of course I realise now that almost all FF constructors are actually demonstrating thier incredible innovative skills rather than trying to change the world, so won't want to "Pollute the purity of thier innovation" by using avaialble components.

It would have saved me a lot of effort if I'd understood this forty years ago - but I would have had to get a proper job.

*Voyager HCS. 38 degres of lock each side, 150mm suspension movement, ten components in the unit, not counting stock M8 and M6 fasteners and the brakes or wheel rim (spoked wheel) but including the ball joint (£10) and the two (stock) wheel bearings and seals. Approaching 500,000 fleet miles, minimum 50,000 miles to first replacement part, that ball joint, which can be changed without removing wheel. See any Voyager pic on this site.
