Which Brakes Are Better

[R32 GT-R]

the other thing i think worth mentioning is that although the g4's are 8 pot, each piston is very small it almost seems a comparitive force could be made by a big 4 piston i.e the stock brembo gear, it would be intersting to know the total surface area difference between the two calipers...

Good point !

The big advanage is that you get to run a 356mm x 35mm disc and a whole lot bigger pad than standard which helps no end for brake fade as it contains more metal, aluminium bell and a larger surface area. Not to mention the advantage of the mechanical force the larger rotor provides.

I could still brake hard with the standard nissan calipers but heat would get to them in the end. The G4's brakes harder than the standards units i have no doubt about that but you can only brake as hard as your tyres will allow and i found after moving to slicks the standard caliper could just not get rid of the heat fast enough and ended up as brake fade.

Back to the topic of the thread, i was not lucky enough to get brembo on my R32 so for me it was to buy the brembo or G4. Brembo are 10 years old and 324 x 28mm G4 was new and 356 x 35mm with aluminium hats and new pads.

The fact that they seem to work well with the std BMC it would suggest that the total piston area is about the same. Most the advantage comes from being able to run the larger rotor...and hopefully a more rigid caliper.

very interesting

keep us posted with your research chris

could you not run a larger rotor with the 4 pot brembo's to give the same effect? or is the slightly larger physical size of the calliper and thicker rotor that help with heat dissapation that make it more worth while?

You could run a larger rotor with stock brembos, but there would be a bit of stuffing around with brackets and the like to get them to work. If someone came up with an easy(and cheap) way to fit bigger discs to stock brembos i'd defiantly consider it. I think the biggest improvement comes from the bigger disc, the bigger caliper/pad probably plays a small part in dissipating heat as well.

I agree with what Troy has said above. But i don't know shit.

Someone lend me the std Brembos with pads for two weeks and i will trial fit them against some rotors i have and see what the max size we can run is. I have some 365mm rotors i can try, also 340 and 355mm rotors we can try them with. Just need the calipers and pads to play with

Why not? mine are sitting in a box for the next 5 weeks, I guess that will be long enough. You definately don't need the discs?

Can send em down with a mate who commutes to melb if you want.

had DBA 4000's on my 32, and ive got brembo-ness on my 33 and thats now cranking near 600rwhp.......but due to running circuit pads in which i have spares of.....im looking for something more streetand softer so they break harder with less warming up time.

Trent can you perhaps helpme out with some URAS pads???

There you go Troy, get Duncans and let me know how you go

[Beer Baron]

you can send them with me if you want duncan? i'm heading down on thursday, and I'll be seeing troy plenty so easy for me to give them to him?

As above old boy, unless your still in and out of the Cas? Get Rich to be a border mule!
