In case anyone it's reading this, the above info is correct, all you need is: -GT/Glanza Carriers -GT/Glanza Discs The calipers and pads are interchangeable (not sure if the ABS pads are the same) The upgrade is.WELL worth doing, a cheap job that will make a big difference! No longer feels like I'm about to rear end the car in front haha. It's worth doing on a stock NA or a mildly tuned one like mine. It's very good for fast road use and I've booked a few track sessions so hopefully they'll still hold up on track with some Redstuff pads!
