Pro-Adjust service components for the Cusco MZ helical rear LSD on R180-equipped GC8, GDB, GRB, and GVB STI models. Helical units don't wear the way plate types do, but preload can still drift from spec after high-mileage track use. This kit retunes it on the installed unit.

  • Retunes preload characteristics on an installed Cusco MZ helical rear LSD
  • For R180-equipped GC8, GDB, GRB, and GVB STI models
  • Worthwhile maintenance after high-mileage track use

Fits: Subaru STI (GC8/GDB/GRB/GVB), R180 rear differential with Cusco MZ LSD.
