Suspension

Lowering my Fiat 850 (again?)

While waiting for the overhaul company to finish the engine of the 850, the new leaf spring from Abarth-Online / Scuderia Topolino arrived today. Deliverd within 3 days from Germany, quite fast. This is the one:

After two previous experiments that did not give the desired result, I finally bought a lowering spring with the eyes reversed.

As a reminder:

  1. Experiment 1:
    Fazaplaat,
    Short shock absorbers,
    Standard "A"-arms,
    in combination with this adapter (the red "A"-arm is not the standard part!):

  2. Experiment 2:
    Fazaplaat,
    Short shock absorbers,
    Standard "A"-arms,
    in combination with these adapters:

    I was basically satisfied with this setup, but the "stance" of the 850 was not good yet: the front is still too high in relation to the rear (there are lowered coil springs and short shock absorbers there).

    What I have now built is the new lowering spring with the setup of Experiment 2. And that had to be done on the floor of my garage because I don't have a lift.
  3. The Faza mounting plate with the old leaf spring must be removed and the stabilizer bar must be disassembled. Then the old leaf spring has to be taken off the Faza mounting plate and the new one can be installed.
    Not difficult, but it is not pleasant to work on a cold floor.

    The lowering blocks from Abarth-Online / Scuderia Topolino. They are installed on the threaded end of the "A"-arm; then the triangle is mounted on the blocks. Lowers it all by ± 2 cm.

    And outside into the cold for a photo opportunity. Car looks better now, front is  almost as low as the rear.

Low! Low! Lower! Lowering the front of my Fiat 850

My Fiat 850 has a "Faza" spring mount plate in the front and it was once the intention to lower the car a little further with an adapter:

That was not very successful: the overall lowering was limited and alignment became a a bit of a challenge as the camber turned negative quite extremely. Filling up with shims was not enough. So adapters are removed again. I visited the Abarth-online.de stand at the Padua  fair and they had something that immediately appealed to me: a new type of adapter, less steel and faster to install and, not unimportantly: without negative camber:

The stance of the car still is not what i want but the car has not driven yet.

Still working on my Fiat 850

Although one wouldn't believe it while visiting this site, but something is still happening to our 850! After weeks of doubting (and working on) rear disc brakes, we decided to install drum brakes. For the disc brakes, I would use parts from a 124 Special: the caliper holders and the front anchor plates and the rear calipers. Everything was prepared but unfortunately I could not come up with a good solution for the load-dependent brake regulator. The rod between the two sides would pass through the flywheel housing and there is already a flywheel. So back to drum brakes. Because I had not taken this into account, all parts had to be blasted and sprayed and, which was less convenient, we had to invest in parts again. Fortunately not much but still. The purchase of lowered shock absorbers and rear springs is a lot more expensive.

The rear wishbones are now mounted, the brake lines are on and the lowered shock absorbers and rear springs have been installed. Everything was sprayed at the front and built into the newly made Faza spring mount. The parts are not tightened yet because maybe later the cooling tubes have to be installed underneath and I don't want to pry everything out again. The revised steering knuckles with disc brakes are installed, also with lowered shock absorbers and so the car sits about 4 cm's lower. The pedal block has been rebuilt after blasting and spraying, the items in the tunnel are getting installed and we have mounted the gearbox and the rubber around the clutch housing. I bought the rubber in Padua at Cicognani. Lots of rubbers for a lot of Italian cars.

Not much done but useful work. A leafspring for the Fiat 850

A party? Then the metal doctor isn't available. But because there is always something to do  started in good spirits with the modification of the leaf spring of the front suspension. The intention is to lower the car by about 4 centimeters. Enough for exciting looks, but that way there is also some comfort left. There are two options:
1) you take the crossbar apart, but then the vibration damping also disappears, so the fillings in your teeth fall out/
2) you saw the eyes of the transverse leaf spring and you weld them back on upside down.
Now I know my welding qualities and they are not good enough so that is outsourced. But grinding just works. This looks dangerous but because of the sharpening angle I am not hit by debris!

Result is to be like this (this one belongs to an Abarth 850TC)

Klaar

When the leaf spring comes back from the welder next week, I will have the welds checked before I rebuild the spring package. Safety first!

Update: even though the inspection showed no flaws in the weld I since bought a proper leafspring with reversed eyes.
