Hello everyone! I've posted this reply in another forum here on GTROC (not the brakes/tyres/etc section,) so in case you do not see my reply I wanted to post it here as well. The simple answer to get rid of squeaking is a set of Carbotech 1521 Bobcat pads for the street, which also allows you to swap to a set of Carbotech XP12 pads for the track without having to resurface the rotor. Here was my post:
Hey guys, if you want the best of both world's (slightly better stopping power than factory along with no noise and less dust,) then you'll want to purchase a set of Carbotech 1521 Bobcat brake pads. These are Carbotech's entry level brake pad for street use, and our second best seller next to the XP12 track pads. Our clients rave about their great performance and quiet operation, not to mention they are very rotor friendly! Standard brake pads are made of iron and carbon, which form carbide. Carbide is used in metal cutting tools, so you can imagine what they do to your rotors! Carbotech uses a proprietary organic material that is lighter than semi-metallic brake dust, and also has better heat tolerance properties, making it a win-win situation.
Here are our Carbotech front brake pads:

And here are the rears:

However, you should NOT put any brake pad on your stock rotors other than the stock pad, due to the fact that the stock rotors are already bedded with the stock pad's metallic material, and therefore will not mate (bed) properly with the new brake pad compound. So, we also offer a COMPLETE street brake package which includes AP Racing J-hook rotors front and rear, Carbotech 1521 Bobcat brake pads front and rear, a set of DOT approved stainless steel braided brake lines, and 2x bottles of Motul RBF600 DOT4 brake fluid for $2790 plus shipping:

We are a leading Carbotech dealer for the GT-R market, and are happy to help if anyone has any questions! For those of you who track your GT-R, we recommend the Carbotech XP12 brake pads. However, due to elevated levels of noise and dust some people will swap the pads back to the Carbotech 1521 Bobcats for street use, as the material from both of these pads will interchange on the same rotor with no need to lathe/cut/turn the rotors.
