Braking system upgrade

Hello again, just a question about upgrading my X6 brakes.
im on my 3rd X6 now and feel my baby needs more stopping power,last year i i changed everything new calipers pads and disks,buy i have seen on the xedos owers page on facebook that some owners have upgraded with other mazda braking systems. I thing someone fitted Mazda6's calipers pads and disks to the x6 with no problems just plug and play,the disks and pads looked a lot bigger so im sure this could be the right move for me,also thinking of adding steel braided brake lines to improve thing a little more to, Has anybody else upgraded to this set up before? does it work? fit easily? much improvement?
i dont really know what calipers,disks,pads would fit to the x6 so any suggestions would be fantastic.

Thanks again guys.

Here are the brake lines i was looking at.

Our user Artemmka from Lettland (speaks englisch too, so ask him) has Mazda 6 GG (non-MPS) breaks in his Xedos 6. I had the pleasure to drive his car on one of the last Xedos meetings and can confirm that it breaks far better than the original Xedos breaks.

As I remember you also could use Mazda 6 MPS breaks too, which should be really far better. Assumed your rims are big enough for that large brakes...
