Received both front calipers – they’re sweet. For now the adaptor brackets will be hand-made; a CNC version will come later if builders want a set 🙂

Cut off the zip-ties and wrapped the front wire harness in nylon split-loom, which is much cleaner and maintainable. Welded on mounting studs for rubber-line clamps for both the wire harness and front brake circuit. Need to pick up two brake fluid T’s so brake line length can be measured and ordered. I have mixed feeling about bothering to plumb and fill the brakes since they aren’t really needed for the dyno session. It’s the time, and getting brake fluid in all the lines that’ll later be dust magnets when everything’s stripped off the car for paint.

On the other hand, it would be reassuring to have working brakes as it’s driven on and off of the trailer. And of course, the clutch system needs to be plumbed and filled; I’m curious what it’ll be like to operate the twin-disc clutch. Some people say it’s a light switch – on or off and no in between. Other people say it’s the only way to go and very easy to modulate? Some much for hard facts on the Interweb, lol.

After the brakes and/or clutch are plumbed, the car is finally coming off the table; there’ll be a lot of moving stuff around that weekend. After that, the drivetrain is reinstalled so all the various tasks counting on it being there can move ahead.

Of course, there is one more chassis-related issue that hasn’t been decided: how the rear portion of the chassis will be finished up. I have no idea. It’s purely aesthetic and be dealt with after the dyno session – that’s the immediate pressing goal. It’s not a big deal since it’s easy to work on even with the engine in place. Things are moving along.

In other news, my buddy Alan urged me to consider Wiggens clamps on the fuel filler pipe instead of hose. In an accident they could help retain the filler tubing on the tank, and are strong enough that if the pipe gets yanked sideway, it can crimp it shut. Alan’s seen his share of very bad fuel fires during his time on an IMSA team. No, I’m not building an IMSA car, but accidents are always a possibility so they’re being looked into. At around $100 each, they’re serious hardware, but so is a fire…
