Helical MZ front LSD for the GDB, GRB, and GVB Impreza WRX STI, cut with 35°/45° ramp angles. Ramp angle determines how aggressively the diff loads up under acceleration. This spec builds front lock sharply and quickly, for drivers who want immediate traction response on corner exit. Pairs well with an RS or MZ rear LSD on a balanced STI track setup.
