You will be fine with stock. If you do struggle, check cable adjustment and brake shoes.
In line hydro handbrake is terrible. It should a separate system or valving should be used.
Agree with this guy
I do. It's not wank factor. Most people that use them rely way to much on them which can lead into bad technique.
If your serious about drifting, start standard and when your skill improves, then increase the performance of the car. A standard R32 handbrake is fine, if it doesn't work you've got problems you need to fix.
I would hope Handbrake isn't the most common entry technique.
