Helical MZ LSD for the front differential on a wide range of Subaru AWD platforms — fits the GC8 Impreza WRX, GDA, BR9 Legacy, BM9 Legacy wagon, and SH5 Forester. On AWD Subarus with an open front diff, this is one of the best bang-for-buck handling upgrades you can make: it stops the inside front from spinning up and killing your exit traction.
1-way spec keeps it feeling natural on the street; the car just goes where you point it instead of fighting you.
