Our wiring trays are 2-3/4" deeper than the original trays available from Exomotive, for a total of 5" deep. This is the maximum tray depth you can have before running into fitment issues. If you plan on putting a lot into your wiring tray, especially if you're using an ECU which is taller than the Miata ECU, this is a must have.
Our trays are laser cut and bent by a computer controlled bender. The lid is included, as will free shipping within the lower 48 states!
