Brembo Gt Big Brake-kit

[Ironman]

Hi !

I am a new member in this forum and I live in Europe-Germany. I drive a 92er Nissan Skyline GT-R with HKS GT-SS-Turbos mostly on "Autobahnen" (no speed limit), no serious track days (sometimes "Nürburgring-Nordschleife").

I have the stock brakes (Sumitomo calipers 4/2-pots, 296/297mm drilled rotors), but now I want to upgrade to Brembos.

There is a kit developed for the R32:

1B1.8020A R32 Front drilled 2piece-355x32mm rotors, 4-pot-Alu-monobloc calipers with 40/44mm piston diameter and

2C1.8008A R32 Rear drilled 2piece-345x28mm rotors, 4-pot-Alu-monobloc calipers with 28/30 piston diameter.

The price is o.k.: 6328,-US-Dollar at www.vividracing.com.

The rear stuff is o.k. for me, but I want the 6-pot-M-family caliper.

There is a kit for the R34 GT-R:

1M1.8030A R34 Front drilled 2piece-355x32mm rotors, 6-pot-Alu-monobloc calipers with 28/30/36mm piston diameter.

And I saw in this forum, that someone in Japan makes adapter plates for the R35 GT-R-brakes to convert it for a BNR32...

How much work, parts and costs it will take ?

What size and brand of wheel you running?

Personally if i was going to run a Brembo caliper i would stick with the F50 range of calipers over their monobloc 6 pot calipers

[phunky_monkey]

Why is that Troy? Due to piston area, or the design of the caliper?

[Roy]

Well compare the bridge of the 6 pot Alcon

With the bridge of the 6 pot AP

Then the 6 pot Brembo (So many variations of them, but typically they are like this)

As you can see imagine the caliper when its nice and hot with high pedal pressure trying to force the piston and pads to squeeze the rotor. You can imagine that the caliper wants to baloon out under the load. The AP, Alcon all have more robust bridges with either big bolts or bolted sections between the sides of the calipers.

Looking at the Brembos you can see they have less meat through their centres and accross the bridge. So compare that to the old 4pot Brembo F50s

You can see they are a more compact caliper and have bolts through the caliper halves ensuring rigidity. The 4 pot has an open bridge design but as the caliper is smaller i do not think its as critical on a smaller 4 pot caliper.

So of course the Brembos are designed to be more open accross the tops of the pads and have meat and mettalurgy on their side to counter this. Its just that i like to see meat in the caliper, in a street caliper then extra 300grams isnt going to kill anyone, unlike a race car where they want as light as possible and do not mind so much if they have to life the caliper more often because it is no longer as rigid. Which is another aspect of monbloc vs 2 pce calipers. Calipers with bolted sections are going to be better over a long hard life of heavy use.

Anecdotally only have to look at how often Carrera Cup guys change out their calipers

BUT, truth be told, grab whatever you can get a good price on. Its a matter of bee's dicks and what makes you feel all warm and goey on the inside. I personally would take the Alcons every time, but when dollars are factored into it i think the F50 is the way to go

Cool, thanks for the info.

I'd heard a while back that the 'Big Reds' had a warping issue, and to not go for them second hand, so this is the reason why.

if you have cash why not go something like the mines AP racing 6pot kit

[bnr#@]

Dare I ask how much that kit goes for?

[Mr. Keets]

"Open Price" that cant be good lol

[Roy]

Here is the thing, why go Mines AP kit, why not just AP? Especially since they are running the older range of AP calipers and these days they are using RDD rotors in their R35 upgrade kits. The Mines badge would be cool, but would never pay more money for them, it would be like getting Mines Bridgestone RE55s for your car, at a premium of course

What a toss, looks like Mine's bought all the old left over stock from the 90's....

Unless this pic was taken in the 90's....

I was speaking to my brake mechanic last week and he told me to hold off until the end of the year when a couple of popular racing categories are moving to a controlled brake package and said that I should be able to pick up some used top quality calipers for $1k/ea.

used kit on yahoo lol...

brembo is better. ive used ap, alcon,brembo f50 and brembo nascar monoblock.

the brembo monoblockpictured is a gt3 caliper?.

the ap, alcon and 2 piece brembos are a gravity cast alluminium

brembos use a better aluminium and dont flex as much. the bridge bolts used in them only offer a slight increase in strength.

we use the ap ones pictured in the utes, really not that great. taperd pad wear and melted pistons etc etc..

the forged ones dont flex as much. and are reflected in the 4-5k per caliper that they go for.. lol. also they offer much more wheel clearance. ie 355mm rotors under 17's

or.. v8 supercar. 375mm under 17's

ap is the most bulky. shit of a caliper if you dont want to run 18's or bigger.

those mines ones look cool. but that caliper is nearing on 15 years old in design. prety much all the "street" range of calipers are cast. racing ones are forged.

also worth looking into is the pad availability. alcon and brembo have that coverd. and share alot of shapes. if it is used in nascar then the pads are cheap.. ebay heheh

most of the kits you can buy would sugest using 18's. b ut the 6 pots do need more clearance.
