ISR’s 4-line brake line kit for the 2006-2013 NC Miata — a complete set of four lines, front and rear, for cars still running their original NC brake hoses. If you’re doing pads, fluid, or calipers on an NC, replacing the full set of lines at the same time is the right way to do the job once.

Straight with you: ISR doesn’t publish material or construction specs for this kit on its product page, so we’re not going to invent any. What we can confirm is the fitment and that it’s a complete 4-line kit for the 2006-2013 NC.

• Fitment: 2006-2013 Mazda Miata (NC)
• Complete 4-line kit (front and rear)
• Construction/material specs: not published by ISR
