Lighten the load of your crankshaft and increase the power of your Subaru BRZ, Scion FR-S and Toyota FT-86 by using the Tomioka Racing Lightweight Crankshaft Pulley. This pulley takes the load off the crankshaft by using quality aluminum and reducing the pulley weight by 63%. The factory crankshaft weight is 4.85 LBS (2200g) compare to TR weight at 1.75 LBS (794g). This allows your engine to rotate more freely creating more power and faster revolutions.
