GT86 TOUGE NIGHT RUN (RAW) 

The flywheel from competition clutch is 6.2kg, I don’t remember how much it’s the stock one, but it’s a little more heavier. If you’re going to replace it, buy a lightweight one, you’re gonna “gain” some “torque” or in other words, you’re gonna gain some reactivity of the car and it’s gonna feel faster than the stock one
