355 Does anyone know how many F355 came with the "Fiorano Package"

My 1998 Berlinetta F1 RHD has it from factory

 

I think it was available for all and could be retrofitted as a kit from Ferrari. As to how many, I doubt anyone knows except maybe ferrari.

 

No one knows the exact number, but I can make an educated guess. Outside of Serie Fiorano cars, the FHP option was primarily available in UK/Euro/Japan markets. Was not available in U.S/Canada or Australia. Might have been available in New Zealand, but that is a very small market.

The option is available for all 3 models. I have seen 1-2 Spiders in Japan with FHP options. 99.9% are ordered from the factory. Up until recently, there’s no record of anyone fitting the parts on (fully complete) after the fact. Too much unknown info to execute properly up until now.


I keep track of worldwide manual B/GTS’ equipped with FHP. I have between 15-20 cars. The cars I don’t know about? Who knows. Let’s say there’s 30 cars.

Since it is only a 98-99 MY option, my guess is it is harder to find a car equipped with FHP than it is to find one equipped with carbon seats. Most 98-99 355’s are F1. Let’s say 75% of cars. If you stumble upon an FHP car, chances are it is F1.

Using this to extrapolate, I’d say roughly about 100-150 355’s outside of Serie Fioranos worldwide max.

 

26 out of 100 Serie Fioranos are manual. I think that’s a good sample to gauge manual/F1 ratio for the 98-99 period.

 

There was a factory 'kit', probably only available in '99 to move the parts as they were transitioning to the 360. A search on here will uncover the parts list in the kit they offered. Be super tough to verify a car had it installed, but I'm guessing if they put together a kit there had to be one or two sold....

 

FHP. Cf seats were offered from 95-99 and my guestimate is 200-300 cars worldwide. But only a GTB/S option.

However, if you count the 100 Serie Fioranos, it’s close to even.

 

The only information from the factory is this…

Easiest way is to take a look at the rear lower forks. If they are straight, it is FHP.

 

2.75 turns lock to lock.

 

Not the A arms. Small pieces. I am referring specifically to part #177707. This part on standard cars curve up. Easy to spot looking from the rear.

Only part of the FHP is derived from Challenge cars. Challenge cars do not have this rear fork. They have standard rear forks. I have a pic of this on an FHP car somewhere.


All you need to do is look at your Serie Fiorano and standard Spider rear forks and you’ll notice right away they are different .

 

I think there were 18 UK RHD factory Fiorano speced cars.I dont know for the rest of the world. I also think a one or two of the 18 were shipped to Australia.
There were quite a dew more that were retrofitted in the UK by buying the parts (bot not all comprehensively)
Easiest way to spot them is the red calipers and drilled rotors. If you have access you can also do the steering lock test or open the passenger footwell and see the ECU that should say Fiorano.

 

Only things they really share are the uprated sway bars and steering rack. FHP is for street cars aiming for a higher level of street performance. Challenge cars are track-focused setups.

 

Exactly. Drilled rotors and colored calipers were standard options outside of FHP. If trying to determine if a car is FHP from the outside, the rear forks is the best bet as only a few people know that was part of the kit.

 

And just to be clear, the Bilstein shock ECU will say Fiorano on it.

 

I think the only bespoke part of the whole kit may be the programming on the shock ecu - but that's not verified. The springs were used elsewhere (512TR?), the rear suspension forks were from the 348, brakes were available outside of the kit, sway bars, rack and pump were challenge parts. So Ferrari grabbed a bunch of stuff they had already, whipped up some new suspension geometry and called it the Fiorano kit. My suspicion is the shock ecu programming is the same as the challenge, but outside of Ferrari there's probably nobody that could verify that. As an aside - this may have been the first Assetto Fiorano kit that later became a regular option for all of the cars.

Now that's not to say it isn't better, I'm sure it is and was probably track tested extensively at Fiorano, but I don't think a single part was created just for the kit, they took stuff that was already built. Not sure if that matters, but it would make the stuff less rare - though it's all relative. Shock ecu is probably the hardest to find, it's not different than the stock unit physically but has different programming. Indeed, some of them were reprogrammed stock units as the Fiorano sticker and part number were just applied over top of the regular stickers.
