355 Fiorano Handling Package Vs Challenge Suspension ECU.

These are the wrong springs actually. These are the late model 512 TR springs which comes standard on 355s .

 

Problem is, the only thing available brand new on that list is the rear sway bar . You can certainly try though.


Apparently, someone bought the NOS Fiorano/512TR rear springs. Someones been reading my posts .

 

… and there you have it folks. The last brand new F355 OE Fiorano rear spring set left in the world. They are made by Eibach (commissioned by Ferrari. Not available from Eibach), just like the standard springs. It’s progressive profile is clearly shown. Now it’s time to do some testing .

How’s your search going so far ? Let me know if you find a front sway bar .

 

Regarding sway bar bushings, I believe Energy Suspension has proper replacements, but I’ll have to double-check.

Comparison with standard springs (far left and right)

Manufacturers:

Fiorano Front - A. Cagnola Monza
Fiorano Rear - Eibach (Germany)

Standard Front - Eibach (Germany)
Standard Rear - Unknown. Has brass ring around coil with part number. Most likely same as whoever made the sway bars.


Ferrari was all over the place when it came to choosing who to use to produce springs.

Fiorano rear springs. At the highest points, with the set I received, one spring is noticeably a few mm higher than the other. Fronts were pretty close in height. These are all new, never installed.

Big thanks to @Yassa for coming thru with the challenge/fiorano front anti-roll bar. Last brand new one left in the world?

Many might not be aware, but Swift Springs can also produce sway bars. Made in Japan I believe. I can bring it up to them and see what they say.

These Fiorano fronts are solid. They’ve got some weight to them.

 

If not, I do have another company in Japan in mind. They’ve already made the rear bars on a 355, just not the fronts for whatever reason.

There is some discussion of running the rear bar being adequate, but I don’t have the experience to comment on that.

T.W.S made splined bars for the 360, so they definitely can.

 

I noticed the 355 has 2 different product numbers for the front roll bar link. 161813 & 170075. I'm going to assume one is early and one is late version. Will the Fiorano front roll bar work with the early version (which I most likely already have) or will it require the newer version (170075) ?

For those who have FHP, are your brake pads yellow front and rear or front only?

 

Do you know which Pagid Yellow specifically?
