Fiat 132 spindles and brakes on 124?

Post by Sparky » Thu Feb 22, 2018 7:13 pm

I saw mention of this swap on an Australian forum and then more recently when a European vendor listed some for sale. The idea is that the fiat 132 spindles, hubs and brakes offer about a 25mm drop, sturdier spindles, larger diameter rotors, and more modern calipers.
It looks like the upper control arm would sit about 25 mm higher at the ball joint as well tho.
Anyone have experience with this setup?

Yes, been around the AU 124 site for a good while. Don't recall it being touted on Mira ... ? I would try to make them work if I had a set actually in my possession .... send me some and I will install , test them and report back ....lol I once broke a front stub in my 1978 Alfa Spider thought ... when it was barely a 5 year old car ...

Pera posted this picture on FB with the 132 spindle on the left and the 124 on the right.
Relative to the bottom control arm, it looks like it would drop the front 25mm and it's certainly a larger diameter.
I'm wondering if the upper arm is going to run into the bump-stop too quickly or that it'll change the camber or some other alignment factor in a detrimental manner.

There is a discussion on the Fiatspider.com about this. The drop is only 7mm not 25. It does move the upper A-arm up, thus changed the camber gain curve as the suspension travels. yes need to trim the bump stop. You can use the stock 124 calipers and caliper bracket but will need to space out the bracket about 10mm.

From the lower ball-joint to the centerline of the spindle looks to be a lot more than a 7mm difference. Springs and shocks being the same, that is what's going to make the difference.
Good to know about the extra spacing for the brake calipers, I'm in the midst of developing my own Fiat 500 caliper mounts for my Spider and the extra thickness would be a plus. I was thinking of just using the 132 rotors and calipers, but I've already got a couple good sets of the 500 brakes and they have (much easier to source) vented rotors.

These are exactly the spindles on a 124 volumex spider

On the volumex spider the brakes are vented and the calipers also different (from either pre-85 or 85.5) but that's a different story

The bump stop on the volumex is also shorter

P.S. the volumex used the same A arms but bumped the bottom one out 10mm or so

The bolts on the crossmember are longer to accommodate this

That combination appears to work well, at least felt good to me every time I drove it :) and over any bumps

The question is, why? 124 Spiders are not known to break spindles, and big bumper cars sit high at the rear, not the front. So to even out the stance one needs a set of lowering springs, but I'd guess the front would end up being too low with lowering springs and this spindle. Oh, and where is one going to get replacement bearings and seals in the US?
It would make sense for racing, but to me for the street it has as many disadvantages as it has advantages.

You say that now, but I bet you can find a supplier and we could probably see these on Autoricambi as a new performance product with replacement bearings and seals soon enough :lol:
I'll take a set of drop spindles over reducing the suspension travel any day.

Reinforced front subframes with longer studs to allow more negative camber (spacing out the lower arms) would be a cool new product as well. The 10mm spacers on the Volumex just won't work on the stock subframe, For this first go, I've got 7mm spacers in and think there ought to be enough remaining room to shim the arms for proper alignment, but it might be close.
