Mirafiori 1600 upgrade to 2000/TC

Oh yes, you have a nice combo there. If sending to Ireland seems to be a problem, just send it here to Czech rep:)

you wish! poke around in austria, you're bound to find one. it's from austrian steyr fiat 132. as you probably know, steyr is better known for their off road vehicles, so lim.slip diff is their speciality

[wak131]

Yes i know about Steyr, thanx for the tip. Austria is not far from here, so i could probably do a trip there if i don?t find anything nice around here.

Hi, I found a ?73 Fiat 132 1.6 Special for sale in a poor condition, but with the disc axle in. I?d like to ask if i could mount the calipers to a 131 axle straight or i need to weld some fixture for it?
Exactly the part that is not visible on your photo of the axle here
thanx

[djape1977]

hmmm.... 1600 special....
rare as bird's milk.
would be a real shame to scrap it.
how bad condition?

[wak131]

I?m posting it as a new thred as a 132 for sale...

discs on 132 rear axle
i hope that you can see on these what you wanted to know

[wak131]

Thanx for the pics djape , if i see it right the brakers and discs are the same as on the front of a 131, but to be honest i don?t see much of what i needed ... the mounts of the braker (caliper?) on the axle. How are they conected to the axle, that is what i was curious about.
Sorry if i didn?t express myself clearly

Hi Ale?,

I just picked up on your thread and I hope this might help.

My Volumetrico has a modified 132 rear axle with disc brakes so see attached pic.

The ends of the 132 axle have a 10mm thick mounting plates for the caliper cages to bolt onto.
These plates are held on by 4 bolts that go into the end flanges of the axle.

The plates and calipers are also found on the 124 Spider 2000 rear axle.

I have tried to outline the plate in the pic but it is a bit grainy.

Oh i see now!
I was a bit confused, but it?s clear now.
Thank you guys!

A Spider 2000 is even more rare than a 132 here and i know about just one 132 ...
So i?m thinking about going for it, because the price for the whole car is probably less than for what i could have the brake adaptors done. I?m just not sure if the owner will be happy to hear i?m not gonna save it...but i don?t want to lie about it, damn.

My Volumetrico has a modified 132 rear axle with disc brakes

I've got a 132 disc rear end in a 131 I'm wrecking. Is the 132 rear end the same width as the standard 131 rear end? I've got a set of 6" x 15" wheels on my car, they just fit inside the rear guards. If the 132 rear is any wider I won't be able to fit it without butchering the bodywork.

It should be wider just as much as those two

That means you have just added the Panhard rod? Or any other modifications?

[Gremlino]

The whole rear axle is an old conversion done sometime in the 80's by a 131 racer called  N. Buttrice.
The pickups for the sway bars and Panhard rod are all original 131 and have been welded in the correct posititions on the 132 axle.
I think it was the only way at that time to get a reliable rear end without building a Fiat/Ford hybrid.

I refurbished the whole thing and fitted it to my car when the diff let go in the original 131 axle.

It could be wider but because I did not compare the axles when they were both off of the car I'm not sure....all I know is that there is plenty of clearence on the outer face of the Revolution wheels that I use, so much clearence that many have suggested that I fit spacers behind the wheels to make the rims fill the arches better.

If your wheels rub you can always fold the arch lip flat under the top of the arch to make the gap, if not enough then you can machine the back of the rim and the disc/hub face slightly to again give the neccessary space.
Its all trial and error and plenty of offering up to check gapping. 

I hope this is not putting you off, I've found that the advantages of having the stronger 132 rear have made my car a much better drive and it doesn't lock wheels up.....incidently...when I took my car for its MOT the tester was gobsmacked by its overall (F&R) breaking strength on the rollers, he said it had more than a modern Ford Mondeo with discs all round...not bad for a 26 yr old car  .

i wrote in some other thread about brake conversion on my 132d. same thing as with gremlino's 131. extremly good braking!
