Just curious as to what you guys think is a good price for a pair of Alfa 166 from calipers?
Also which models of 166 have the calipers suitable for the 305mm discs, and are these the same calipers that are suitable for 330mm discs as well?

No one?
I've seen a pair up at €230, is that about what other people have paid?
Hello Steve!
166 has 310mm discs and as I read somewere else at least someone has used the calipers also with 305mm discs on the Q4. So that seems to work fine.
I heard about, that 147 GTA had 305mm discs at the beginning and lateron became 330mm discs. Referring to ePER also the calipers were changed:
7189NEW POWERED FRONT BRAKE SYSTEM T?tigkeitsbeginnDAT 10-2003 (V6) DAT 12-2003 (V5)
As I drive a 166 3.0 I can try to have a look at the calipers... probably I can find out if the calipers could fit with 330mm discs.
BTW: The price in ePER from the year 2005 for ONE caliper of the 147 GTA (the big ones for 330mm discs) is around 350,- Euros.
Best regards, Martin
Yep the 166 caliper is quite a common upgrade for the Q4, using fiat Coupe 20vt discs as they still have the right stud pattern for the wheels. You just need an adapter plate to make the calipers fit the uprights.
Being tight with money, I'll be going for a second hand set and refurbishing them.
I think the price for a pair of calipers depends on the condition they are in.
Have seen an asking price of ?250,- and up. Some with pads and discs and some for the calipers only. On average I think they go for abuout ?300-350.
I'm thinking about to use the front Q4 calipers with discs on the rear (without ABS, one brake line to the rear and a hydraulic handbrake with manual adjusting for brake balance rear-front) and 166er brembo's on the front...
Front discs should fit at the rear without great problems...
Does anybody know, if the front calipers fit on the rear axle without mods?
Thought I'd move this as it seems to have gone into a tech discussion rather than about the price of the calipers.
I've never heard of anyone using std Q4 calipers on the rear, should fit under the wheels fine, but as for the calipers fitting onto the hub? No idea.
166 brembos in Slovenia are reachable from 100euros to 20euros max. 330mm discs can be fitted from mercede benz ( i dont know witch model ) with some modification.. ill check at friends catalogue for discs.. for the rear calipers it can be used caliper from vw transporter with 280mm at rear
I think that the 166 calipers work very well. They won't fit under some 16" wheels however..The problem with the 166 caliper / 305mm fiat VT disk is that the disks are a bit small - especially for racecars. I would really like 330 - 350mm calipers...
Colibry - if there is a 330mm disk that fits on the Q4 hub, I'd love to know which one..
I would need to move to 17 wheels however and that would involve quite a bit of guard modification...
I'd expect to pay ?120-150 for a pair of good 166 calipers in the UK...make sure you get the mounting bolts as I hear they're no longer available from Alfa (in the UK anyway!).
They were fitted to the V6 models.

They should still be available, I thought manufacturers were obliged to carry spares for any model for 10 years after they ceased production. Since the 166 went on until 2007, spares shouldn't be a problem.Quote:

I did look around on ebay uk for some 166 calipers but there didn't seem to be any about. Any other places good for them?
The real problem for me Jan, is that on 17" rims's I'd want to use 240mm slicks - that would be 9" rims on the rear and 8" on the front..I'd need a fair bit of guard modification to make it all work..

don't the wheels touch the wings when you tturn the steering wheel?
Hi all!
I found following a few weeks ago...
Up to 400mm x 36mm discs with 8 piston calipers:
http://www.xyz-racing.com/index.php --> Brake Kit
or
http://www.k-sportracing-switzerland...vorn_list.html
But you'll need 20" rims (perhaps they fit without rubber at all) :lol-052:
and it's a little bit expensive, I think :unsure:
jim,
i now the problem had it too as you can see in the second picture
the toyo r888's are 215/45/17 and did not fit so i'll need 205/45/17 or something, why do you want that size?
the oz wheels sometimes touch the wings, we need to make the wings wider
marc,
I asked about your wheels, but you did not respond?
Mine are et37 7inch
That's a pitty, thanks for the trouble.Quote:

Do you guys know what specs of tyres are good for 8J?
I have thought about 225/45 for the rear and 215/45 at front. I'm affraid that 205/45/17 on the front wheel might be too streched for the 8J rim...
Cheers.

About 10 years ago I had a big problem with a 33 Permanent 4.
The viscous coupling was destroyed (got a leakage and the viscous oil was lost after permanent overheating) because of different wheel diameters on front and rear.
As far as I know the Q4 has also a viscous coupling on center diff and I think that 225/45 for the rear and 215/45 at front could maybe destroy your viscous coupling!!!
I would stay at the same wheel diameter for front and rear wheels.
There's something written about in the repair manual.Quote:

Guys, do you mean that I should stick to same spec for TYRES for front AND rear? For ex 215/45/17 for both axles?
Or do you mean that it's a problem if front rim has ET28 and the rear one has ET25? It's only 3mm plus for the rear...
What about those who have diffrent spacers for front and rear? Like 16mm for rear and only 5mm (or none) for the front. I'm sure I've seen here this kind of wheel fitment configuration.
Cheers,
Cristian.
As far as I know you should definatly stick with the same spec in regards to circumference tyres on these cars.
However, as tyres wear out - say the rears have 8mm tread and the fronts only 2mm tread - is this safe for the viscous? Hope so as that what mine was running on!
Different spacers or different ET on front and rear doesn't effect the wheel diameter.
On the 33 there were mounted 185/60-14 on the front and 195/60-14 on the rear as I bought it. Just later on I noticed that the 4WD doesn't work anymore. I changed the viscous coupling to a functioning one and got extreme vibrations after a while of driving. I was wondering about this up to the moment I noticed the different wheels. I changed the wheels and everything was working fine...
215/45 front and 225/45 rear (tyre hight 45% of 215mm vs. 45% of 225mm) means that the diameter of rear wheels is bigger than the diameter of front wheels and there is a permanent diffence between the rotation speed of front and rear!
This can destroy the viscous coupling due to overheating!
I don't know how big or small the difference between front and rear is allowed to be?!?
I changed the wheels from front to rear and vica versa every 10.000KM's
Or you can drive it properly and change all four tyres at the same time when wornhttp://www.flitsservice.nl/phpBB/ima..._hypocrite.gif
There you may play around a little bit with all the possibilities and you can see the differences in % and in mm:
http://www.reifensuchmaschine.de/rei...fenrechner.htm
It's in german language, but that should not be the problem at all. :thinking-011:
Oh I see now, I was kinda hasty and need to read some more about diffs...:tongue: ,thanks for the slap over my neck.
I will choose same tyre specs for both axles, 215/45/17 or 215/40/17/.

Hi Cristian,
The standard tyres for the Q4 are quoted as being 205/50r15, Both 215/40r17 and 215/45r17 are have a larger rolling circumference than this. The closer size would be 215/35r17 if anyone makes that size.
I use this Tyre Calculator to work out tyre sizes.
215/45/17 seems to be too big (width and total diameter) as it gets too close to the mudguards or even touch them. The rim is already 5mm outer than the front wing's edge so I will have to go for some tight tyre, something like 205/45/17 or 215/40/17 maybe.
215/35/17 is to be considered indeed, if I'd find that kind of stuff...
Cheers,
C.
205/40/17 or 215/35/17...not 205/45/17, it's too big, 45 profiles are for the 16" option.
wrinx
I use 215/40/17 - no problems.
Tire Size Comparison
Specification Sidewall Radius Diameter Circumference Revs/Mile Difference
205/50-15 4.0in 11.5in 23.1in 72.5in 874 0.0%
215/40-17 3.4in 11.9in 23.8in 74.7in 848 3.0%
205/40-17 3.2in 11.7in 23.5in 73.7in 860 1.7%
205/45-17 3.6in 12.1in 24.3in 76.2in 831 5.2%
Incredible low profile for 205/40-17 (and so very streched especially on 8J rims) but maybe my kidnies would bare 215/40-17.
The hardest thing now would be finding good roads to run with such rims/tyres setup...:ohmy:
Thanks for every suggestion, guys! :thumb:
Cheers,
Cristian.
Does anyone know the difference between 166 and 20VT Coupe Brembo calipers if any? Are they interchangeable?
Well logic dictates that they would use the same calipers, but as well all know with Alfa/Fiat/Lancia this is not usually the case.
Eper has different part numbers for the Coupe 20v vt calipers and the 166 v6 calipers but that could just be down to the different arms of the company.
Also the 166 disks are 310mm and the coupe ones are 305mm.
Personally I can't see any reason for them being vastly different.
fiat coupe have 130mm mounting holesQuote:

Thats quite a difference! thanks
the other diference is in pistons
166 is with 2 42mm pistons and 2 38mm
coupe is with 4 pistons but not sure for diameter
