Clutches and gear ratio. Need to upgrade ?

[Stang_456]

4.56 gear ratio.
Should i use an OEM clutch or should i upgrade to a higher stage ?
Stock motor.

I wonder this because many will argue gears don't increase torque but it sure feels and looks like it.

Gears increase wheel torque, not engine torque. No need to change the clutch just for gears.
