Leave the car upside down.  As the Miata’s rear brakes have a junction box on the passenger side, you’ll want to run your rear brake line along the inside of the passenger side floor tube.  Place this line as close to the bottom of the car (the top of the tube as it’s positioned now) as you can without going past the tube itself.  The goal is to protect the brake line from the ground while leaving enough room for the fuel line(s) above it.

If you are installing our stainless steel braided line option:

Simply run the longest line along the inside of the passenger-side floor.  Make sure you space your p-clips appropriately so it does not sag.  You don’t want your brake lines to be the lowest part of your car.  Leave the rear free, as the junction box is attached to the rear subframe.  Route the front up along the firewall and across to the proportioning valve/master cylinder assembly.

Re-use the Miata clutch line.  A long aftermarket stainless steel braided clutch line is HIGHLY recommended.  As always, wrap stainless steel lines with a cheap hose to protect other components.
