Big Brake Modification
Credit goes to Sub555 and Cream on 155.org.
You will need......
25mm o/d spacers approximately 8-8.5mm thick (best to measure when you can set the caliper in position). I turned these on my lathe but you could just use a selection of washers!

204mm Fiat Coupe Turbo front discs

166 (2.5 or 3.0) calipers (same as Fiat Coupe I think). They are silver but don't take long to paint and the graphics came from ebay. I also remade the bottom pipe with copper as the calipers were about eight years old and it looked tatty!

Mounting brackets, the holes in my brackets are larger, for 14mm and 12mm bolts iirc. You will need the original 14mm 166 bolts, trying to find this size outside of Alfa is hard! Then I also used 12mm mounting bolts. Brackets have to be custom made...

I also needed 15mm hubcentric wheel spacers to clear my wheels, 17" wheels will probably be needed although SOME 16" will fit. 16" Speedlines will NOT fit.

This is not a cheap modification but the results are REALLY impressive!!!

Great modification!!!
Is breaking distance shorter? r just improves thermal fatigue?
-
Braking distance is much shorter and the "bite" is instant! I still have to sort out the rear bias valve so the whole system can only get better.
The brakes on my 156 JTD now feel bad :rolleyes:

Good job, bet they make a difference! I guess the 155 hubs are similar to the Fiat 16vt hubs, I used radial calipers and then had a square bracket made to mount them.
Where did you get the hub centric spacers in 4x98 pcd?
-
There's a full secondhand set on ebay now HERE
...and THIS is like the set I bought, although I've got 100pcd :)

Which is the size of your wheels? 16'' or 17''????
-
I have 17" wheels. Team Dynamics RVO II.
But this upgrade fits under the Team Dynamics 16" RVO I (Sub555 ran with these) with about 1mm of clearance!!!

I have a few questions...
Are the calipers form the 166 2.0 V6 turbo the same?
and the disc is from which coupe?2.0 20v turbo or 16v turbo??
-
Discs are from a 20v turbo and yes, the calipers are the same for a 166 2.0 Turbo (according to ePER).

Hello wrinx,
why 16" speedline (black 5 spoke) will not fit, is the radial clearence the Issue or the axial clearence, is it possible with spacers to fit them?
Regards Michael
-
I think it might not fit BOTH ways :(
Someone on 155.org (Speedy) tried to fit them under 16" speedlines but there's no chance. e ended up using Wilwoods.
I am seriously thinking of changing these now!!!! I have bought a set of Zender Milanos and these will not fit underneath :(
Wilwoods would have to be used with standard 284mm discs...but these brakes are SOOOOOOO good, it's a very hard decision to make :(

-
Great thread mr wrinx.
:thumbs:
I have looked at wilwood calipers lots of times as they really arent that dear, and do have a good reputation,
but i always get stuck on which version and size would be the best for a 1300 kg car ???
-
how much wider is the bigger caliper? i have a set of calipers, discs and hubs from a 20vt coupe at hand here, but im not sure about my wheel clearance.

i believe you need about 65mm from the disc face to the spokes of the weel....
-
Sounds familiar...I wrote the measurements down recently but have lost them!

the 166 calipers differ from the 20VT coupe and 156/147GTA.
on V6 and Q4 the uprights from the 20VT will fit with the calipers and discs from the 20VT/GTA. However, you will need the 2.1 quick steering-rack from the widebody to make it all work and fit and steer properly. You could convert the narrow-body rack, but the 2.1 rack is much nicer anyway. The calipers from the 20VT/GTA stick out even more, most 17" wheels will need spacers.
D2 racing taiwan has 6pod calipers with mounting kits that will fit the original discs (284*25mm). These kits are actually advertised on their site for the 155

Hi!
Does anyone here knows if the calipers from a lancia kappa 2.0 20V turbo are the same as those from an 166?
I saw in catalogues for discs that they share the same front discs and as i asked those one from the lancia is also Brembo.
-
Pictures and measurements would help.
-
Thats the problem ...becouse i only know that they are 4-pot brembos with the same disc size,offset....The brake pads are the same also i checked in the omp brake pads catalogue.
Even the year when FIAT started to put this calipers on the 166 matches with lancia's :)
-
ePER does not list any other car for the Kappa 20v brakes...which is odd, but they could still share pads I guess.
wrinx
-
maybe they have a different colour or print on them, that would give them another number in eper... don't want lancia on my calipers ;)
-
Could please someone post here the measurements(the distance between the mounting holes and so on.....) and some extra pics of the 166 calipers?
I just got the calipers from the lancia and they look very very similar or the same....so i must see a few pictures and measurements so i can verify more precisely .
Thnx
P.S The print on them is just Brembo and the colour is black.The part number for the calipes for 166 is ....735266839 for the lancia is 735266838 :)
I will post some pics later.
-
-
They look the same to me....only difference is the tiny writing and logo in the first picture.

Another mistery solved :D
Lancia kappa 2.0 20V turbo front brake calipers are the same as the 166 it at least look like that :D
