Overview

They are precision waterjet and TIG welded in the USA. These ducts increase rotor and pad life and improve brake consistency.
Show original supplier description
The Singular Motorsports 3" brake ducts are constructed from lightweight aluminum with precision waterjet and TIG welding, and are made in the USA. These brake ducts fit all 1990-2005 Miatas with wheel sizes 14" and up. For hose compatibility, 2.5" hose fits with factory undertrays requiring minimal modification and can clear 15x9" wheels without spacers. The 3" hose option typically requires a non-factory or fabricated undertray to clear 9" wheels or larger; however, with the factory undertray removed, 3" hose will clear 15x9 and 15x10 wheels with a 5mm spacer. The manufacturer recommends using the largest diameter ducts that can be accommodated for maximum cooling benefits. Reviews indicate a significant improvement in brake performance during track events, with users reporting enhanced confidence and better lap times. Installation is described as straightforward, with clean fabrication noted by customers.
