MZ helical rear LSD for the R180 differential used in the GC8 STI Version 3, GDB Impreza WRX STI, GRB STI hatchback, and GVB WRX STI — a wide cross-section of WRX STI generations in one part. Replaces the factory Torsen or open rear diff with proper helical-gear lock-up that engages on acceleration and keeps the outside rear driving the car out of corners.
Zero maintenance, fits the factory housing, and immediately makes these cars easier to be quick in.
