Full 2-way MZ helical rear LSD for Sure-Track-equipped Subaru models including GC8, BR9, BM9, BP5, SH5, and SHB — Version 5 spec. Works with the factory traction control rather than triggering false faults, while still providing genuine helical 2-way lock-up.

One of the most practical upgrades for a daily-driven WRX or Forester XT that also sees weekend track use.
