To hard-anodize the aluminum brake caliper brackets carries a batch charge of $110, whether one or 100 pieces are done. So the interim plan is to iridite coat them, wait until the car is  done, then decide what to do with them. Perhaps there’ll be enough other aluminum bits and pieces that the entire batch can be done at once. If not, they can either be left as-is, or more likely, be powdercoated (basically for free) along with all the other parts (though this time, masking the mating surfaces – lesson learned there!).

After that’s done, add the helicoils, bolt them on, then face reality: the car’s true weight. It’s complete enough now that it’s time to learn what it really weighs, not what I want or hope it to be. Some time back I weighed the bare chassis, and it was no accident you didn’t read about it, because it was very humbling to see the scale spin to 275 lbs. Granted it consists of basically a full SCCA roll-cage, but still, it’s a tank, at probably twice the weight of a Locost, but far safer and 3-4 stiffer in torsion.

My brother’s Super Stalker weighed in at 1600 lbs, and Kimini weighed in at about 1580 lbs, basically the same. Leading up to this weighing, my brother asked “So how is Midlana going to way sooo much less like you say it will” – good question. The differences in favor of a lighter car include: lighter drivetrain (-70 lbs), no doors (-60 lbs), no large composite shell (-50lbs), aluminum floor versus stainless, and no side or rear windows (makes up for Midlana not having a windscreen yet), and that’s about it. Differences in favor of a <em>heavier</em> car include: a turbocharger system (+50 lbs), heavier wheels and tires (+50 lbs) – with all weights being off the top of my head so they’re give or take.

So what’s your guess? I’m guessing 1600 lbs if expecting the worse, 1500 lbs if hoping for the best. Stick in a 1600 cc engine and 15″ wheels and tire and it would be probably 150 lbs lighter, but I didn’t want to go that way for mine!
