After a bit of advise really running octavia vrs front and soon to be rear brakes looking for better stopping g power ie ferrodo ds2500's do I need to upgrade rear pads or are stock oe pads enough on the rear

Thanx

Stock pads will be fine on the rears.

You should never fit high friction pads on the rears unless you fit the same to the fronts as you'll end up doing some pretty impressive skids under heavy braking.

Thought I may get more response to this

OE on the back, they're not powered after all and the brake force distribution favors the front anyway.
