Coil packs, just get the beru ones from anywhere else, what Porsche use. Amazed your paying Porsche for the plug change, they charge like £350-£500 to do it, most specialist will do it for £200 including the parts.
Disc, buy from Porsche they can give upto like 25% discount on brakes, so ask them nicely and all 4 should come to £600-£800 which is good for disc.
If you need rears and my 997 rears fit, you can have those very cheap as they are near brand new and I am putting ceramics back on.
You can also have my pads if they fit, don't think they will as I think my brakes are a lot bigger, but again check, I am on 6 piston front and 4 piston rear.
I will give you my Porsche contact, email me and I shall introduce you to him he will be able to tell you what if any of my brakes will fit to your car and he will sort you good prices.
