MZ helical front LSD for GC8, GDA, BR9, BM9, and SH5 Subaru models — same application as the 180A but the B suffix typically denotes a 1-way ramp-angle variant. On the street you won't feel a dramatic difference, but on track the improved front traction consistency is immediately noticeable on exit.
Helical-gear design means no maintenance, no clutch pack, no drama — it just works.
