Lawson's 818C

  • Brakes
    • So I think I’m finally at the end of the power brakes project. Unfortunately, the MazdaSpeed 3 booster would not fit in the space provided. I actually got a lucky break because the dead Miata forum thread regarding 1″ master cylinder’s came back alive. NC Miata owners found that a G37 brake master cylinder is also a Bosche unit that fits and it has a 1″ bore. Third time is the charm I guess and the G37 master bolted right up to my NC Miata booster.
    • I have not evaluated the pedal feel change yet because the G37 master has M12x1.0 inverted flare ports (fairly rare). I had to order the fittings off ebay and I’ll make my own brake lines from the master cylinder to the ABS module that incorporate both M12x1.0 fittings and M10x1.0. Then I should be able to test everything out, but I expect it to at least be a solid improvement.
    • Parking brake handle installed. FFR’s mount design is fairly poor and mounts the cable at a weird angle which makes it rub on the mounting panel. I had to modify mine and I will still have to clean it up later to improve the appearance.
  • Electrical
    • Replaced an engine harness plug that I broke with a connector from iWire. Fairly simple but these connectors are always a pain to deal with. Still glad I didn’t do the whole harness.
  • 3D Printed Parts
    • Radiator mounts: These replace some pieces I made from aluminum square tubing. Much less likely to puncture the radiator now.
    • Intake mounts: The first print mis-printed, but I waited to make another in case I needed to revise the geometry. Which I did! So I will change the design and reprint.
    • Future Parts:
      • Throttle Pedal Mount: 3D printing will let me easily adapt the existing bolt pattern and angle the pedal how I would like. I can also incorporate a built in pedal-stop.
  • Seat brackets reinstalled
