MZ helical front LSD for the GDB, GRB, and GVB Impreza WRX STI with 35°/45° ramp angles — the specific ramp cut determines how aggressively the diff loads up under acceleration. This ramp spec gives a sharper, quicker-building front lock that suits drivers who want immediate traction response on corner exit.
Complements an RS or MZ rear LSD well on a balanced STI track setup.
