You must be confused, i mean that the stock 147 / 156 has a 2 piece, caliper + bracket, 4.8kg, and i did not add any weight, my setup with bracket and brembo from 20vt is 1.3kg lighter
No, I am not confused - you did not specify you were talking about the stock caliper, so I thought you were talking about the stock 305 set up.

You have still added 800g per side of unsprung weight over using GTA uprights, which is the best way to go because you dont add to the usprung weight (no bracket needed) and you also get corrected camber so better handling characteristics (I m assuming your car is lowered) and less inside tyre wear.

Lol you have the photos of the weight comparison, so yeah you're confused.... i have to compare the weight to what i have at the moment not gta uprights which is a lotttt more expensive, so with regards to the stock setup is 1.3kg lighter yes?
My car is lowered and i have camber correction on the upper arms....
 
No I m not confused and I ve told you why, read my post again.

I know all about the weight of the 305 Brembos/discs, the 166 Brembos/discs, 159 Brembos/discs and stock calipers/discs as I made comparisons when I fitted them all to my cars.

I just pointed out that youve added unsprung weight compared to using GTA uprights.

You have not saved any weight - the std 305 Brembos + discs + pads weigh 12.83kg, the std calipers + discs + pads weigh 12.8kg, you have brackets weighing 800g, so your set up is not 30g heavier than std as it would be if youd used GTA uprights, it is 830g heavier due to the brackets. Now, the figs can vary slightly due to different makes of disc and pad, but even the lightest 1 piece 305 discs are only 300g lighter than the heaviest, so even if you use Brembo made 305 discs (09.6843.21), youve still added approx 500g of unsprung weight. Unless you plan on using 2 piece discs, but they cost more than GTA uprights. And thats before adding the weight of the camber correction kit. (I also had a set of these but sold them as I used GTA uprights in the end, so dont have the weight of them to hand).

As I ve said, others have claimed that theres not enough material to safely make brackets for 305 Brembos on std uprights and I ve just repeated that, if youve proved them incorrect, then great, well done - I m all for disproving conventional wisdom, I wait to see the pics of them fitted.

But you have not saved any unsprung weight, youve added it.

Ok, you have won the photos speak for me, 4.8 kg vs 3.5kg the rest is just a lot of rubish as you say.
 
This is not a competition, its a discussion, so I have not "won".

You are not counting the (heavier) weight of the 305 discs or the weight of the camber correction kit, so you can post all the photos you like, the only thing they say is that youve forgotten something.

Loool you also can write whatever you want but the fact is that original brake caliper + bracket is a heavier than my brembo calipers and steel bracket, yes i know th discs are heavier but whats the big drama? The thing is you can upgra de your braking system fairly cheap.
And the bottom line is that is possible to fit the gta 1st gen brembos on std uprights... You still haven't told me where is the weakness on my bracket, because you can clearly see where are the holes and if there is material to be safe or not, but i get it, its best to be negative about other things like weight.
 
You obviously want a fight, look elsewhere for it please, not here. Or maybe quote the people at the beginning of this thread and try and pick a fight with them, but dont try and pick a fight with me. Better still, grow up and try not to pick fights with anyone, just politely say that youve managed to do what others though impossible and have an adult discussion, you never know if you had a less confrontational attitude maybe people will congratulate you, but please dont try and pick fights, its not helpful to anyone.

You have increased your unsprung weight, but you said you had decreased it, I was just pointing out your mistake (unless of course I have misunderstood you and you intend to use the car without discs ?!). I have already pointed out several times that it was not me who said that there was not enough room to safely make a bracket to use 305 Brembos on std uprights, I was just repeating what others have said, I ve also said several times well done if youve proved conventional thinking incorrect. I cant proplerly judge who is correct here - conventional thinking or you - until I see pics of them fitted.

Dude i dont wish to fight you, i just said that the weight of the original caliper and bracket is heavier... why are you being sarcastic? I was never rude to you. Ive asked you multiple times where is the weakness??? No answer, you prefer to rant about weight which is not relevant to the main issue, if you wish to hide behind those ridiculous claims, ok but do not make me the bad guy!!! Yes its not helpfull to anyone to pick fight's but also not helpfull to give bad info, based on stubbornness or lack of vision of some users!
So it wasn`t you who said it wasn't possible to fit them, but you keep repeating that is not, so where are the evidence that the fitting is a problem? Where are the pictures? Just rant and rant and i am the one who needs to grow up, dont make me laugh, your childish behavior says it all, just keep repeating the same thing over and over again, with no real facts to back it up.
Maybe you are the one who could grow up a bit and post some real evidence that such an application is not possible, but no, i just posted photos of the brackets and brembos fitted, that you and all the other enlightened ones posted here that was not possible, without even proving their clames witrh facts or photos!!!!
But whatever makes you happy, when the brakes are done will post photos and you can find another aspect to rant about, because i just dont care!!
Maybe from now on people can upgrade their brakes without spending a ridiculous amount of money.
 
I see that both of you are correct in a sense.

typos1 compared Ncosta's setup to 305mm with GTA upright. The GTA upright solution is lighter.
Ncosta compared (without discs and pads) his setup to the stock setup. His setup is lighter and he is not taking into account the GTA upright solution for his own reasons (e.g. costs, availability). I would also say that he is not taking into account the discs and pads in the comparison because that is not really his focus.

Ncosta, many people would be interested in your solution because it means we can reuse the many 305mm calipers and most importantly we can do it cost effectively. Therefore many would be interested in looking at photos of your setup when you have it.
Even when you have managed to do it, I suspect there will still be argument over whether there is "enough" material to safely do so. But in this case we can check all the dimensions and everyone can decide for themselves if it is "enough". (Enough in quote marks because lacking all data and extensive mechanical testing, there will always be an element of opinion.)

Hi,
I dont care about weight, and much less 830g of it, i saved a lot more in just changing from the stock wheels to those gta speedlines i have now to be able to use brembos without spacers... left side is ready, photos of the spacers are here and you can see if there's enough material or not, but like i said i will take photos of the caliper fitted today. I already know when i do that another major issue will be pointed out here, so i could care less. Of course everyone is free to have their own opinion on this but the fact is just that such apllication is possible, and people can choose without having to sell a kidney to able to fit better braking system to their old 147/156's.
The main thing is that, some users will always be against this, just because they are not willing to accept they were wrong. I find it stupid that like i wrote before, some guys here just claim that is not possible without even proving this for a fact, and me posting photos of the caliper and bracket fitted, there are always this doubt's, i guess hater's will always hate.
Look, i didn't reinvent the wheel, i have gone for this because i know for a fact is possible after finding a friends car is using this same setup on his 147 for a long time now.
 
Hi!
I have used the knuckles from Alfa Romeo 166 on my 156 as you did on your pictures, and also I have a point visible on your second photo where the pillar of the knuckle is hitting the strut mount on longer wheel run-up, like on deep road holes, speed bumpers, etc
Have you solved this problem?
I mean, it is very loud in my case, it is impossible to use the car on a longer run.
Thanks a lot!

No 166 knuckles, original 147, no problem whatsoever
 
I have got some "new" brackets for sale. These are clones from the original MiTo QV Brembo calipers, except these are 1 kg lighter and made from hard anodised alumium 7075. ;) Should fit the 147, 156 and GT (except GTA / 3.2 V6) and GTV-Spider916 2.0 V6 Turbo and 3.0 V6 12v no problem. The Brembo calipers from the: Fiat 500 Abarth en Grande Punto Abarth, Renault Clio RS en Megane RS, Opel Corsa OPC / Vauxhall Corsa VXR can also be used.

Prices: 155 euro incl VAT for one set (2 pieces). Shipment to the UK will be around 15-20 euro's. Payment possible with banktransfer/IBAN (excl additional Bank or currency costs) or paypal (+10 euro additional service costs). I have only 7 sets for sale. I don't know if there will be a new production run of these brackets in the future. That depends if there is enough demand...
Do they fit to Corsa opc? Or only the alfa romeos you mentioned?
