The GT-R SuperKit has the largest brake caliper, rotor, and pad upgrade available for the GT-R, with the front rotors having a massive 15.75� x 1.42� (400mm x 36mm) size, and the rear rotors coming in at 15.16� x 1.30� (385mm x 33mm.) The kit’s 2-piece floating rotors also include Alcon’s unique bobbin drive system and crescent groove pattern on the face along with 48 internal vanes with turbulators. The mammoth sized ‘Mono-block’ calipers are machined from solid billet and contain 6-pistons in both the front AND rear, along with dust seals, anti-rattle clips, ventilated piston inserts in the front, and utilization of the OEM parking brake in the rear. The brake pads included are Pagid RS9-2 models, with anti-squeal shims and a surface area of 33.6� square inches (217 square centimeters) in the front and 18.7� (121 sq cm) in the rear. High quality Goodridge stainless steel braided brake lines complete the kit. And, best of all, these huge brakes fit inside the OEM 20� wheels and work with the stock brake actuation system!

Pretty much brake porn right there… Pricing on the full SuperKit is $12,990 including everything you need and a choice between Castrol and Motrul brake fluid.

Surely such gigantic iron discs must increase not just the unsprung mass but the rotational inertia at each corner?

The price is quite frankly crazy. Better off waiting for the Stillen carbon ceramics if you want to spend crazy money on a set of brakes.

In the meantime, the AP/Alcon OEM replacement discs with some Pagids should be enough for anything bar full-on 24 hour endurance racing!

In my experience, you can't really get better than Brembo for the calipers.

The Alcons use a Alloy bell and differenty internal structure so they don't increase the weight over the cast standard unit. The Caliper is much stiffer than the OE Brembos. Carbon discs are under development as well.

I wouldn't use AP discs on a 35 after experience with them on a 33/34.

Unless AP have radically improved their discs, there's no way they'd be up to half decent track work in a 35.

I was wetting myself laughing at how much they cost and the fact you wouldn't be using them to their capability as you still have A BEUT! :chuckle:

BTW, there's a couple of pics of your 35 at Santa Pod in this month's new Redline mag. Including a close up of the Alcons...

& in the back of Jap Performance, maybe I should ask them for Royalties!!!

Well let’s just see how an 11 year old R33 stacks up against the might of the R35 tomorrow, if the weather is like it is today it should be a cracking day!

As for the Alcons, watch this space Bruntingthorpe on Sunday and JP at Bedford on 31st August

Endless have a brake kit similar priced... Only a few users bought them but there is a huge difference in everything.

I think people get distracted tho... These kits are for race cars... Also people like them for show cars.

Carbon ceramics also have down sides... Why don't they use them more in motorsports... Plus they get so hot u need to take extra precision to monitor there temps... This again is for race teams.

Stillen and ap are co developing the carbon ceramics... and stillen is making a cooling pack with fans to cool the brakes.

Alcon is making a carbon brake setup as well...


Both brands are leaders in many motorsports as well as other brands like PFC.

If ur running into a limit u need to upgrade or change ur driving style... However some upgrades are far more than anyone will use. It depends on the whole picture... Is it an endurance race or a heavy braking track do u brake too late too often etc.

A lot of races still don't use either carbon products is all I'm saying. And since that's pretty significant you could argue that the alcons, endless, pfc and various others will work fine for most r35's even in high stress race environments.

Carbon ceramic has its advantages for being very light, lasting very long and in many cases braking much later. Another downside I hear is they can break. U have to be gentle when handling them... Another reason they don't want to bring the spec-v to america lol.

Both are great solutions.

I will say there are better calipers than the r35's and they do make a difference. Ur buying more than a rotor and pads with the alcons.

Frankly I don't know of what races your talking about. When carbon brakes are not used it simply because they have been banned as a cost saving measure.
Personally I'll wait for the AP-racing CCM before buying or not buying those Alcon.
