Audi q7 s lines run a 330mm disc and brembo callipers to match on the rear. Could be a cheaper alternative to the 166 Alfa callipers. These seem to be getting quite rare and pricey.
Look at this on eBay http://www.ebay.co.uk/itm/201588141306

it may run a 330mm disc but the brake pad in the calipers look tiny. would have to look into that

Problem solved smile

After 500-600 miles and proper bed in of the pads/discs - braking is stronger and no early triggering of the abs smile

Last week I took part in the Bulgarian Track day for Italian cars and I won second place with the coop smile No problems with the brakes during the event smile

Lancia delta 3's of 09 vintage use 330mm discs that look like they will fit directly onto a 16vt hub. I have ordered some part number Brembo 09.A500.10 (superceeded by the coated version 09.A500.11)to be fitted with the alfa 166 4 pot brembo callipers and a spacer bracket to get the correct axial offset.
Disc thickness is the correct 28mm, PCD is the correct 4*98 (rare size) and hub center is very similar.
I will update if it works, i think others have done it on other forums but haven't found anything on here.

I have this setup on my coupe, it works perfectly !

An other member has also this kit and there is no problem. wink

No, (je vois qu'il te reste un peu de Français wink )

In fact, going 330mm only gives you something like 10% more "front stopping power" from 284mm discs (I had made a calculation but don't remember where I put the file).

This 10% are nothing on the road, and installing sport suspensions/short springs will increase braking power on rear wheels (less mass transfer and the brake valve linked to the rear anti-roll bar will be less active = more brake pressure).

Stock rear solid 240mm discs are big enough even for track day. laugh

Can't find any info regarding the bracket for the Alfa 166 caliper together with 330x28 disc. Do you have a CAD drawing Julien?

Totally agree, but i guess you know that if using wider front tires, slicks or semi's, this 10% will be more than that.....
IMHO the biggest advantage of 330mm is that they can not overheat.....even on trackday.....harsh trackday.....

Yes of course it's more for endurance than stopping power as original discs with good pads are enough...but only for 1 or 2 big stop, after they nearly burn crazy

No - Alfa 166 Brembo has 150mm bolt distance and 20VT brembo is 130mm......

I believe GTV 24v 4 pot calipers bolt straight to the Coupe 20VT uprights.

I'll double check as I have a set and some spare Coupe uprights, but I kind of matched them up a year or so ago and recall they seemed to bolt straight on.

I must admit I thought 166 calipers were the same but have never had a set to play with.

The calipers of the 20VT, 406 Coupe, GTV and the first 147/56GTA are all the same(130mm bolt distance and 305x28 brake discs). But the 166 and the Lancia Kappa ones are different, they have bigger brake pads, 150mm bolt distance and 310x28mm brake discs.

So,

This is the adapters drawing to put 20vt calipers + 330mm discs on 16vt hub. Thickness of the main part is 20mm and material is stainless steel.
You can go smaller if you want (like 12-15mm) but for me, not having any hesitation when hard braking at 250+kph easily worth 300grams more on each front hub

click to enlarge

You need to add some big "washers" of 8mm thick. those are visible on this photo :

click to enlarge

The small weld has just a "location" role, not strength, also you could weld it all around (that's what I did).

If you're not sure, I can give you a contact to have them made (main part + washers + 12.9 grade bolts) for something around 150€ a pair + shipping cost.

Regards

It's better save than sorry, but i'm a "less weight as possible" freak, and was OK with 10mm thick bracket.....Driving AR 156, 1100kg, with 250\64\18 full slicks in front.......Just for your information, it's not advice or recommendation..... cool

No problem it's always good to have some returns from others wink.
I wonder one thing : your brackets also have 2 threads in it or did you use bolts + nuts for mounting it on the hub ? (that's the main reason I took 20mm because I wanted to have bolts directly tightened in the adapter with max torque for 12.9 / M12, which is something around 110Nm. I know this is well overrated but this way I can sleep on both ears laugh ).


@t Begbie : thanks for the image redirecting (didn't have access to host server at work... crazy laugh )

20vt calipers use smaller pads than 166 4pot Brembo. IMO there will be around 10mm of the brake disc that will become rusty because disc/pads won't contact with each other there.

So what is the point of using bigger discs (330mm) when the pad area remains the same as with the oem smaller disc (305mm) ?

Those adapters are for 16VT, not 20vt.
Anyway, even if you put them on 20VT (with 16VT hub) you will have more braking power because the braking point is further from the wheel rotating axis.
You will also have more endurance as the discs are bigger (more energy/heat can be absorbed).
Pads area is always linked to pistons area/pad material : put a giant pad with a hard compound on a tiny brake piston and you will get nearly no braking power.

Just to be clear, as ferrarist said above, the Alfa 166 callipers are a larger bolt spacing than the 20vt brembos and the template above will not suit mounting them to a 16vt

Interestingly the slave piston size is 42mm on the Alfa 166 brembos, which is I believe the same as the 20vt. In theory either calliper will transmit the same effective force.

I have now amassed the parts required to convert to 330mm discs with Alfa 166 brembo callipers and am pretty excited. The callipers are in great condition and have excellent piston freedom and fit. The discs seem huge and are coated in the central ducts so shouldn't rust on the non friction surfaces for a while. I ve cleaned and coated the callipers in a gloss res to make the car faster and the brakes even better smile .
I have new steel braided lines also and a pressure bleeder to get all the air out. Now I just have to wait until I have the time to do it. In the same place as the car and get the brackets machined.

click to enlarge click to enlarge click to enlarge

pretty excited anyway.
If anyone has a template they wish to share for these then it would be much appreciated. If not then I will share mine when i have finished the fabrication.

Does anyone have a CAD file for 20VT OEM Brembo calipers to use them with Delta III 1.8TBi discs?
