Big Brembos installed

[cooberpedy]

I thought that it could be of interest for someone.
Fitted bigger Brembos all round.
front:

rear:


with 18" wheel fitted:


The rotors are 365mm X 34mm with Brembo 8pot Calipers.

looks nice, but how much are they compared to a 6 piston AP set up?

[chuntington101]

Are they off an RS6? Isn't there are carbon option?.....

Nice!
Though of more interest to me are the wheels what fitment and size are they?

Looks like it's the OZ Alleggerita wheel

To be honest, i have no idea, how much they are in comparison. But i like the fact, that they are used by a few OEM's (Audi, Lamborghini), which should give superior reliability.

The pair in the picture are labeled to be used in an Audi RS6, the other pair, i have, is labeled to be used by Lamborghini.
But will change color anyway...

The wheels are one piece OZ Racing ALLEGGERITA, which are very very lightweight.
rear: 13"x18" at 10.5kg and front: 10"x18" at 9.5 kg.

ciao.
I bought a plant used in a vw touareg tdi or cayenne and I was thinking of trying to install them on my gtr.
but it seems very weigh much kg.
i think 6 or 8 pots

[ezakimak]

Are they hub centric pcd adapters I see?

hi stefano,
actually, i had an eye on the cayenne ones also , they are 6pot and are all designed for different disc sizes. The biggest one, which have in my "cayenne turbo s" are 382mm and they only fit under 19" rims, at least.


For my understanding, there is nothing to be gained, by just installing a different caliper and sticking to tiny rotors.
Only increasing the disc size to the maximum diameter in conjunction with an appropriate caliper, will result in ultimate stopping performace.

I honestly doubt that there is any sense in increasing the ultima rotors unless you are using slicks on a track......

hi uwe,
probably the truth, perhaps one of the "endurance racing guys" can comment on this.

yep!
They change the pcd to a porsche 5 x 130mm, which is more common, at least in my country...
The major advantage is, that this massively increases the choice of wheels, designs and manufacturers , which can be used.

I have 365mm Rotors on my Ultima with Hi-spec monster6 calliper's,(not fitted by me) I would say that you need less pedal effort compared to the AP set up, however I would suggest the AP set up will save close to 5Kgs of un-sprung mass per corner, so anyone considering "brake upgrades" needs to think carefully about the use the car is being put to.
PCD adaptors and spacers will also add to the un-sprung weight

[845ste]

ola
also seems to me that sufficient new discs from 350/360 with different PCD and adapters

I have to try

however, I saw that there are with 18 "

But then again I seem to be very much kg (Brembo)
bah

[cooberpedy]

5 kilos per corner is hard to beleive....

can someone put the components of the factory ap setup on a scale?
i can do it with my brembo setup.....just for the record.

If the weight saving is really 5kg, I prefer the saving as unsprung weight per corner, especially when taking into consideration the Ultima as a lightweight compared to others.

I'll get my scales out and do some weighing. I thought I had done it when mounting the brakes but I can't find the file...

That is for My HI-Spec set up with 360mm x32/4mm Cast iron discs over the Factory AP four pot 320mm x30mm discs.
The factory Calliper piston sizes have been carefully balanced against the brake pedal mechanical advantage, weight of the car, diameter of the discs and rolling radius of the tyres.
I can think of no reason for fitting anything else other than for full on racing.
If I didn't have "other" things to consider I would change out my set up for the factory set-up.

[UltimaCH]

I did some weighing on the rear brakes only, but from what I can see and imagine, there is little weight difference between front and rear brake assemblies apart from the handbrake of course...

Disc: 6.8 kg
Diameter: 320mm
Calliper: 2.476 kg
Handbrake assembly with pads: 2.0 kg

Front disc ID n°:


Rear disc ID n°:

[cooberpedy]

Daniel!
Thanks for that.
I'm going to come up with my numbers later this morning...

Q: Are your data for the caliper with or without pads?

cheers
