Background


Of the many options and kits available we have chosen the South African Birkin - a kit which faithfully reproduces the beauty of Colin Chapman's original car and which you build up with component parts from the factory, adding in your choice of engine and transmission.



This holds true to the tradition of garden shed mechanics without requiring quite the level of welding skill, or CAD programming, that some of the amazing, home built clubman cars require. Or at least we hope not, as neither of us have done anything like this before.....

Exhaust Heat Shielding

The first upgrade we planned was to heat shield the exhaust headers. I had been warned that there was some radiation from the headers into the footwell, but was not prepared for the reality. As the headers wrap around the drivers footwell they act like the element of an oven. Quite nice at first, but after about an hour's driving your legs start to poach. Any longer than that and in our car at least you can't touch the pedals without shoes on. I once reversed up the drive in socks after a bit of a fang and very nearly crashed. Not terribly smooth when trying to impress bystanders.....!
Our solution was to ceramic coat the exhaust headers and then to individually wrap each pipe in thermal lagging. We went for a black coating, which matches the rest of our metalwork, and have had the exhaust guard painted matt black too. Overall we love the finished effect - we've nothing against exposed metal as it looks fantastic as well, but we wanted a slightly different look.
The results are positive so far - there's still some heat but nowhere near as much. We've yet to take it for a really long trip as unfortunately the car is now immobile again (more anon) but it seems to have done the trick
