GFB 13 Subaru BRZ / 13 Scion FR-S 3 Pc L/W Pulley Kit (Inc Crank/Alternator/Water Pump Pulleys)
It might be hard to imagine how reducing the mass of a pulley makes a car go faster, but accelerating a heavy factory pulley from say 3000-7000 RPM in a second or two saps a measurable amount of torque. GFB Lightweight Pulleys reduce inertia by up to 85 percent, so most of the torque that used to accelerate the pulley can now be applied to the wheels.This Part Fits: Year Make Model Submodel 2013-2016 Scion FR-S Base 2013-2020 Subaru BRZ Limited 2013-2019 Subaru BRZ Premium 2015 Subaru BRZ Series.Blue 2019 Subaru BRZ Series.Gray 2016 Subaru BRZ Series.HyperBlue 2017 Subaru BRZ Series.Yellow 2018,2020 Subaru BRZ TS 2017-2020 Toyota 86 Base 2018-2020 Toyota 86 GT 2020 Toyota 86 Hakone Edition 2017 Toyota 86 Special Edition 2019 Toyota 86 TRD Special Edition
