Fabricated Chrome-Moly Rear Upright

For the technically minded we machine the hub from 4140 chrome-moly and use 4130 chrome-moly in 2mm and 4mm plate for the TIG welded upright construction. Weight 2.3kgs.

Wheel assembly - design and fabrication.

With the X1 'core' chassis locked down on the prototype bench, the next step is the wheel assemblies. This is a major stage in the design process, as decisions made now, will have long ranging consequences on the success of the project. Track, wheelbase, caster, camber, camber curve, kpi, ackerman, scrub radius, tow, wheel travel, track rods, bump steer, sway bars, wishbone pickup points, roll centers and ride height, are all design points that have to be considered and successfully addressed. We use SolidWorks CAD software to resolve the design, before going on to make the jigs and then machine and fabricate the prototype components.

Polarizer included

Jon and Dean have spent the last few days finalising the suspension and upright design details of the X1. This picture shows the moment Jon informed Dean that he wanted to fit a 'Polarizer' to the front of the car. Jon has had some experience with the 'Polarizer', having driven at the 1987 Bathurst 1000 in one of Peter Brocks race cars, which was fitted with a 'Polarizer'. As you can see in the photo, Dean is clearly not convinced. Only jokin' Deano. For our overseas readers, you can read more about the Polarizer at http://blog.rarespares.net.au/post/2016/04/19/Motoring-Myths-The-Brock-Polarizer.aspx Brock described the Polarizer as a “high-technology energy device which creates a 'polarized

Engine wrapped.

I had the pleasure this morning of watching Dean performing some of his artistry with steel tube. He was working on the rear of the X1 chassis, hand notching tube, whilst accounting for tube rotation and bend calculations. Effortless and perfect. Our goal was to wrap the Suzuki GSXR 1000 engine as tightly as possible in tube, while still allowing for engine extraction through the bottom of the chassis. I think we've done a nice job.
