GFB Lightweight Underdrive 2 Pulley Kit - Subaru WRX (GD/GG) / STI (GDB) MY01-02
The GFB Lightweight Underdrive 2 Pulley Kit replaces the crank and alternator pulleys on the MY01-02 Bugeye Subaru WRX (GD/GG) and STI (GDB). Both pulleys are made from aircraft grade 6061-T6 aluminium, taking rotating mass off the crankshaft so the engine responds more sharply and revs more freely, a feel GFB compares to fitting a lighter flywheel. The underdrive ratios cut parasitic losses at the crank and alternator without hurting accessory performance, and GFB has tested them on this application to avoid harmonic or accessory problems. The kit comes in a single configuration with both pulleys and two drive belts.
