Front helical MZ LSD for the GDB, GRB, and GVB STI in 1.5-way spec with 45°/0° and 45°/15° ramp angles. The partial decel engagement keeps the front connected under light trail-braking, which noticeably improves corner-entry stability on technical track layouts. A well-rounded front diff spec for an STI that sees regular track time and needs more than a 1-way provides.
