Front helical MZ LSD for the GDB, GRB, and GVB STI in 1.5-way spec with the 45°/0° and 45°/15° ramp angles. Adds partial decel engagement on top of the standard 1-way lock — the front stays connected under light trail-braking, which improves corner entry stability noticeably on technical track layouts.
A well-rounded front diff spec for STI drivers who track regularly and want more than a 1-way provides.
