So my GT-R has about 18k and I'm going to have to change the brakes very soon. Very insignificant cracks in the rotors and the pads might have 20% of life left.

I have decided I will not go witht he OEM units because theyre way to expensive.

I use my car mainly on the road. 1-5 trackdays/autocross per year. I will also be doing the Gumball in May and there will be some track and very hard street driving. Any recommendations?

This is the track package from speed for sale.... how will it be when driving on the open road?

This is the street package. Is it agressive enough for me?

Any other packages you may know about? Better prices?

Thanks

If you are more 1 than 5 trackdays, then you want to lean towards a nice street pad. If you are closer to 5 or more, the difference is that high temps have a tendency to wear a street brake pad quicker.

Brake pads have a certain range, and you want one that will work where you use it. At a certain point, there is no compromise, you need a dedicated street pad, and you need a dedicated track pad. Both will do what they are designed to do well, but outside that range, they don't work as well as a dedicated item.

GT-R guys run some pretty aggressive pads on the street. The problem with this is rotor wear at low temps. The other is that the GT-R is a big heavy car with a lot of energy that the braking system needs to dissipate.

I'm in the middle of writing a post on brake upgrades and options for the GT-R, but I have some older info I have put up.

Why are the AMS rings so much cheaper than the J hooks?
Why is the Sentra so much cheaper than the GTR?

Do a search on here for AMS brakes. This is not AMS in Chicago, but rather a company from Canada. There were several people that had bad warping issues.
http://www.nagtroc.org/forums/index.php?showtopic=41997&hl=

The materials that AP uses for the curved vane rotors are a much higher quality than the OEM parts. We have guys that do five times as many track days with a set of rotors vs stock. They can handle the heat, and they wear well.

Like any part they are consumable, so the harder you run them, the less time they last. When it comes to brakes, its a very important safety item, so if you are willing to cheap out on it, you obviously don't value your life.

If you ever track your GT-R, do not get the street kit we are offering. We provide the option for people who just use their GT-R for daily commuting purpose only, absolutely not for track use. Per your description, you want to get the track package which contains the AP Racing rotors.

The AMS rings are not made by the AMS shop that is a vendor here. There is another company named AMS that brands and sells these. I know of at least one board member who tried these and they warped very quickly. That is why they are so much cheaper.

I for one highly recommend the J hooks. Great street and track performance. You will get a mild whirring noise when braking on the street, nothing loud. If any noise at all bothers you, consider the AP slotted rotors. I've not tried them, but from what I hear they don't make any noise at all.

Regarding pads, it depends upon how many track events you would do per year.

Other option you can run is a set of Performance Friction (PFC) rotors. That is what I use and also what was used by the Cobb Tuning Time Attack car http://www.nagtroc.o...showtopic=29989 and the 2009 One Lap of America winning GT-R. Benefit is that rotor rings are considerably cheaper than J-hooks and you get a full set of rotors when you buy them, not just rings that you add to the OEM hats. I paid $352 each for spare front PFC rotor rings, and they are hard core racing rotors that have lasted me tons of track days with some very high heat put into them. Downside is that upfront cost is more since you are buying rings and hats together, rather than just rings. But even then they are much less expensive than the OEM rotors, which tend to crack if you get them too hot on track. 2012 OEM rotors which are slightly larger are perhaps in improvement in terms of resistance to cracking, but not sure that has actually been confirmed. However they don't fit prior year cars directly.

As for pads, here are the results of a magazine test on racing pads: http://www.nagtroc.o...post__p__761480

Ok so I will get the J-Hooks as I wont be cheap with my brakes. Any advice on what pad to get with those. http://www.speedfors...6.html?cPath=32
Speed for sale is selling Carbotech XP12 with the package. Is that adequte for the small amount of tracking that I do, as well as the autocross and hard driving?
Good choice on the APs. I would suggest against J-Hooks if you're concerned about pad life.

Regarding XP-12s, just be forewarned that they are noisy, so if you primarily do street driving, you may not be satisfied with the results.

I really dont mind if they are noisy, as long as they bite hard.

Using an out and out race pad when you do mostly street drivng is not a good idea. I suggest the MX72 that others have mentioned or even better, the MX72 for street and Autocross and then the XP12s, (or something similar), for the road course. Pad changes are dead simple in the GT-R. Takes an hour for all four corners and most of that time is taken up with jacking the car up.

Where did you get these? And yes I know they have proprietary hats but these rotors used to be very expensive

I'd strongly recommend our Street Package kit...includes everything you need!

The MX72 have excellent street manners and are also good for the occasional track day!

Click on the picture and it will take you to them on our site!

This. Plenty of good street pads to compliment your track pads.
