This is easily a 4k+ brake system by them time you factor in machine shop milling for the Porsche calipers, brackets from Tronik and used F85 calipers.
I ran the 4 pot system from the E70 X5M on the front of my e70 35D for 6 years, towing a 6000 boat, and it worked well. I initially ran stoptech steel braided lines and then just the stock rubber lines
Tronik sells his brackets and porsche calipers already miled for $1600 USD. This does not include pads or rotors as yet.

If you have the $$$ and time to scour ebay, it looks like a fantastic piece of kit. You are competing with the F15 guys looking to do the same brake upgrade. If not the F15 m performance brake kit is $2495

That is the route I went with my F15.
