ISR Performance Clutch Line - Mazda Miata 06-10

Upgrade the clutch hydraulics on the third generation Miata with the ISR Performance clutch line for the 2006 to 2010 Mazda MX-5 NC. It replaces the factory clutch hose and firms up the pedal so engagement is repeatable, whether you are heel toeing into a corner or inching through traffic.

Benefits over the stock hose

• Less expansion under pedal pressure than an aging rubber hose
• Consistent engagement point from cold start through a full track session
• Direct replacement, no modification to the master or slave cylinder

Why NC owners swap this line

The NC is the heaviest and most powerful of the early Miatas, and it is a common choice for track days and endurance racing. Under sustained hard use, the factory clutch hose heat soaks and the pedal gets vague. Many drivers also report a clutch that does not fully disengage at the top of the stroke on a hot car. A stiffer line is the first thing to try before chasing the master or slave cylinder.

Application

Mazda Miata NC, 2006 to 2010 model years. Earlier NA and NB cars use different ISR lines.

Install

Swap the line in place of the factory hose, then bleed the clutch circuit until the pedal is firm. Fresh fluid throughout the clutch system is recommended.

All ISR Performance products are designed for off-road use only.
