Hello Berlinista,

I noticed you are running brembo calipers at the front. Are those 75/gtv6 calipers?
Do you also have ventilated disks? If you do can yu tell me what are they?

I am trying to figure out or find disk to put into 105 with 75 calipers!

thanks

really simple:
Use TS calipers, take out the alu piece in between, this is for the ventilated discs. Now install a standard, or Tar-ox or whatever 2.0 disc,
and there you are. I run grooved Tarox.
Now, it never ain't that simple.
when you try to fit the caliper to the disc, it will not fit.....
on the back of the caliper is some alu you will have to file or grind away. You will see easily enough.
Then, also you will have to fabricate the solid brake line on the back of the upright, or use one from a 2.0 model.
Also, this caliper fits on 1300/1600 uprights only, not on 2000 uprights!
So its a nicer and better conversion than installing everything from a 2000. It also very decreases unsprung weight.
There....

Thanks for the comprehensive info.
I do have small uprights from a 1300 Junior. I was hoping that you were running ventilated disks! Apprently there is a disk out there that matches a profile required for 105 hubs and is right diameter and and is ventilated.
Using 2 liter disk is good and i will probably go that route if i cannot figure out the ventilated disk!

Well, of course everyone is free to have his opinion, but as being experienced in Alfa racing for about 10 years now, I think ventilated discs are Bull$h!t.
And especially on a street car. you will never get the pads or discs up to temperature. We tired it on several cars over the years, but never got much profit out of it. that's with 200 HP serious racing alfa 105's.
anyway, if you do want that, take a montreal disc.
Or several Audi discs. you will have to machine a spacer behind the disc, to get the right offset.
But hey, try the normal disc first, with a GOOD pad, like somthing from SBS or Hawk, they do street/racing compounds. Forget ferodo, that's racing only, for example DS 2500 or DS 3000. Do NOT buy sh*t like Green Stuff. Invest in a GOOD pad, Goodridge brake lines, fresh master cilinder etc. there you go. Or Stop.......

Berlinista is right abouth the ventilated discs, you don't need them but they are nice to have

I have the small uprights, 75 TS calipers and ventilated discs SBS carbon brakepads, a set I bought at Giacomini motorsports in Holland
The brake disc are stock Brembo, they drilled new holes and are useing a aluminium spacer for the ofset
I allso use Goodridge brakelines and a 22mm ATE master brakecylinder

Have a looked at the brake kit from Alfaholics...pretty damn nice imo:

vented disk & light 4 pot caliper...

Giulia Bianca · #70 (**permalink**) 04-26-2006, 03:48 PM

That's awesome Hans, but that will be very expensive too

vintage prep · #71 (**permalink**) 04-26-2006, 06:17 PM

Yeah, they are awesome, but the billet thing is so 90's. If your going for big brakes on your vintage racer, why not use the 4 piston Merc calipers or better yet, the AP 4 piston Monoblock calipers that were used on many types of race cars including F1.

Like the drilled spring plates and lower arms

4 pot calipers are too much on a 105 even with an increased booster.
You cant really dial in your brakes when nearing a turn. Its all 100% or nothing. I personally do not like that. In my experience, the TS brake mod is by far best. That it is also far cheaper is only an added bonus.

I'd go for the Alfaholics setup in an instant if the disks were also drilled (LOOKS), i think an 105 with a seriously modified engine and 170+ hp can benefit from such a setup , the mov-it brakes setup is extremely cool and also expensive...
The stock brakes are really nice for a 150 hp engine in my opinion
