More speed, less weight!
The GFB lightweight pulley kit replaces the crankshaft, alternator and water pump pulleys, significantly reducing rotating mass at the front of the FA20 engine. The engine therefore revs more freely and accelerates faster, while the vehicle responds more directly and sharply to throttle input.
The factory steel pulleys weigh 2880 g in total, while the GFB kit weighs just 660 g, meaning over 2 kg less rotating mass.
The kit does not use an undersized drive, making it compatible with the original factory belt.
