4.6is brakes on 4.4
 

What is needed for this swap? I assume I can source 4.6is calipers and get everything else new

Currently NHT is not able to sell 4.6 brakes. They recently ran into a problem with their supplier and are trying to find a new one. I know a few websites have them listed for sale but a few days after you order you will get an email telling you that they cannot get them for you. They will of course tell you they are in stock when you call to order. From what I was told at NHT it could be six months or more untill they get a new supplier.

Unfortunatley you do not have many options. The best bet would be to buy a used set of 4.6 brakes. Then outfit them with the Axxis ceramic dustless brake pads and some aftermarket driller or slotted rotors.

Just my luck, out of stock, lol. Thank you for the heads up.
Well that is what I really want to do. Finding the used 4.6 Calipers is the difficult part. If I did get them I could rebuild and have them powdered coated myself.
