355 Fiorano Handling Package Vs Challenge Suspension ECU.

I was thinking the same thing, however, 170075 arm also works with a standard bar (159353).

 

There’s actually a third front sway bar for the 355. For super early cars equipped with mechanical steering. These must be the rarest 355’s as I’ve never come across one.

You can start with getting a bunch of #6’s in the diagram. Maybe #2 as well.

Bushing numbers for the sway bars were posted above. I’ll gladly take your old ones so save those for me .

Thanks. It's nice to have a visual confirmation of these little nuances for Fchat record keeping.


If others haven't already noticed, my posting style on Fchat probably seems like I'm in my own world talking to myself. I use Fchat as a virtual notebook . Makes it easy for me to reference my own posts with pics any time. Lots of little things to keep track of with these cars.

 

Ok. Received an email response from Eurospares regarding bushings for the uprated FHP/challenge sway bars.

"175878 no longer available no alternative

103259 no longer available but you can use 108748 £16.91 each new in stock"


So for the rear bar, they recommend 108748, which is this....

https://www.eurospares.co.uk/Parts/108748/Ferrari

"This part number 108748 is found in the following part catalogues.

Ferrari 308
Ferrari 328
Ferrari 330 and 365
Ferrari 512"


So 355 is not listed. I asked them to measure out the diameter of the hole. If it's 19mm or slightly less these will work as an alternative. Superformance also has available front and rear FHP bushings, which I'm probably going to try out and compare for the fronts.

It's never straight-forward with these cars. There's always something .

 

I've also been looking into Moog bushings which seem to be a special rubber/thermoplastic blend. No squeaking and no periodic maintenance needed. I guess it's sort of a middle-ground between OE rubber and Energy Suspension's polyurethane bushings. They do offer a 19mm and 24mm. I'd like to try it out sometime. They should improve performance a notch over OE.

Here's Energy Suspension's polyurethane bushings. They will require periodic maintenance if one is looking to reduce NVH.

Eurospares sent me pics and measurements of bushing 108748. Said it's closer to 18mm as they didn't want to cut into the rubber. 18mm diameter for a 19mm sway bar. What do you guys think? Yay or nay?

If your standard bushing is worn out enough, one could get lucky and the 19mm bar would slip right in .

 

This MOOG vid says you can get away with up to .5mm undersized. So close, yet so far... Who wants to take one for the team? I know I've taken plenty .

 

Great. Vid link not working here. Search Youtube vid "Moog Universal Sway Bar Bushings"

 

Personally, I wanted the OE bushings simply because everything else I've gotten is OE, so the experience Ferrari had setup for an FHP car would be close minus quick steering rack and tires. We have better tires today, which is good . For me it was simply a matter of logging in the experience of the OE setup as a reference point so I can comment on them if people ask for my opinion. I'd have no problem running better bushings after that and at this stage, since OE is not available, I'll have to run after-market or Superformance's alternative.

I'm also skeptical of using polyurethane bushings as NVH can be introduced if not maintained. If an OE bushing is cheap and easy to swap out, I'd prefer to go that route as the car won't see enough miles for it to matter. OE bushings tend to offer a pleasant road-going experience. Moog bushings look promising as it seems they can give an OE pleasant experience with a bit more enhanced performance.

 

I have come across a few Spiders with FHP in Japan. However, the 2 spiders in the video appear to be Serie Fioranos imported from the U.S and a modest attempt to Euro-spec them… ex… changing tail lights etc. The front and rear bumpers are still U.S with an attempt to block out the side reflectors.

 

Was there ever a product number for the suede covered steering wheel?

 

I do find it interesting Euro tail light specs were needed to bring into Europe, but the amber circle side marker, which is seen on pretty much every Euro-spec 355 isn’t needed.

Embossed fenders on Euro-spec cars already have the circle for the amber side marker pre-cut. U.S / Canada cars do not. They come like this…
