Sambo, the wheels are Vintage brand, just BRM(GT40) style instead of Halibrand. We have a few Cobra guys going with that style due to the timeless appeal of spoked centre design it features.
With the alloy material, total different grade of alloy than what your tank is made of and features superior corrosion resistance etc. But in saying that, for the show type of guys, we have great success with the cleaning and protective wipe on finishes like Shark Hide etc. They just leave a very clean bright aluminium look that is protected from stains and you can't tell the treatment is on there. Easily re-applied if required.
We have analysed the stress areas of the chassis using FEA and measured the stress using Safety Factor of the material and welds, Von Mises etc. Basically we have tortured this chassis design using simulations on the computer over and over with different scenarios. Same with intrusion bars, mount points, suspension pieces, brackets, you name it. We know the simulations are accurate as we can predict the outcome of a physical street registration chasis torsional test for example within a few percent. All stress areas have stronger design incorporated i.e. gusseted and/or heavier material used. This is obvious when you see the chassis in the flesh.
Weld quality is a critical element and we utilise a top of the range Miller Dynasty 350 Watercooled Pulse TIG machine with all the extras(fingertip control etc), correct filler rod and an expert welder etc.
We also have a much stiffer chassis construction and I would say a much more consistant twist and flexure compared to other chassis designs out there. A lot of hours, expertise and expert tools have been used to design an efficient and reliable chassis structure. Of all the chassis I have seen tested, our PACE 427 design has much, much better consistancy. The numbers are publicly available for comparison.
We have also needed to get our own custom extrusions manufactued as there was not extrusions available in the grades of alloy we were looking for.
Won't even comment on the quality of the original Cobra bodies, give me a Kirkham body any day. Same approach, you won't see any issues with Kirkham bodies, quality approach to materials and construction used. We are not supplying 60's quality products.
And the great thing about an aluminium semi-monocoque chassis is that it makes it very easy, clean and efficient to construct into a vehicle as the heavy wall aluminium is a breeze to drill and tap and it is everywhere, even the panels can be drilled and tapped.
I am happy for any scrutiny. I can't stress enough that we have left no stone unturned.
We are still waiting for some of our production parts to arrive for the first batch of 10+ kits, so some aspects will look and work different once the final production parts are available.
Hope that has answered the questions. Did I miss anything?
