    I believe Euro-spec embossed fenders have been discontinued for some time. You can try your luck with Eurospares to see if Ferrari re-introduced them. I doubt it. I got lucky with the U.S spec embossed fenders. Try your luck with those as well. You can always have the hole for the amber side marker cut out.

    Just seeing this, but p-s-t (performance suspension technologies) make polygraphite bushings that give the best of both - poly stiffness but graphite impregnated for lubrication so no maintenance needed. May be worth looking into whether they have some in the correct (or close to correct) size: https://p-s-t.com/c-1176072-suspension-suspension-components-polygraphite-bushings.html

    Patience is a virtue :).

    Getting the parts is the hard part. Getting them on should move rather quickly. Swift still has my springs ;) . But yes, the time has come to get parts on the car :).

    I decided last week it was best to replace my brake lines. Couldn’t find any info regarding anyone upgrading them with the standard setup. Decided to pull the trigger on GruppeM carbon steel lines.

    Just received them. Now we move forward :).

    Did Jeff Segal’s F355 Modificata secretly have a Fiorano Handling Pack installed ??

    He certainly had the quick steering rack and pump, challenge front and rear roll bars, drilled rotors, and “non-standard” springs. I recently discovered he also has FHP Pagid/Brembo yellow pads.

    Did he put the icing on the cake with an FHP damper ECU???




    https://www.pistonheads.com/news/ph-driven/ferrari-f355-modificata--ph-review/41205

    “Crucially, Jeff had no intentions of making his F355 quicker on a lap or more drilled down to the road for a ‘because racecar’ vibe. The lovely five-spoke magnesium Speedlines are a visual nod to the Challenge one-make racers from which he has taken many of the mechanical upgrades. But the dampers are stock, the ride height is actually a tad higher and he chose racing wets for the fact they get a bit squirmy on dry tarmac and let the car move around.”

    “You might consider this a 90s take on the Speciales and Pistas of more recent times, and certainly there’s a sense of that with the F40-spec felt trim, red-cloth on the carbon-backed seats (an option when new) and the harnesses they carry. But where more recent Ferraris cater to driving god delusions with electronic fluffery like Side Slip Control there are no driving modes or assistance functions on this car. What you get out is as good as what you put in.”




    “Of course, the joke remains everything beyond the engine on a Ferrari is an afterthought. These are the areas in which Jeff’s upgrades start making sense. If there were any rattles or squeaks you wouldn’t be able to hear them anyway but that’s not the point. The car just feels taut, without any of the slop or bagginess you’ll find in 20-year-old regular ones, however many miles they’ve covered. And for all the macho noise and drama the controls remain light and easy to use while the car feels alert without being pointy or scary.”

    “There’s the faster rack and new power steering pump from the Challenge car, springs geo perfected by Jeff’s obsessive tinkering


    “The faster rack helps restore some faith in the front end but it’s the smaller F40 wheel and spacing to bring it closer to your chest that really help. Everything feels up to the task too, even the relatively small (but discreetly upgraded) brakes offering staying power while the whole car feels like it could take a proper thrashing without getting all Italian about it.

    By keeping the suspension supple Jeff has maintained the road car’s sense of approachability, the sharper responses telegraphing weight shifts more clearly and accentuating the F355’s natural balance. It’s not as hyperactive as a modern Ferrari, for sure. But it’s easier to get your flow on, the beautifully linear throttle response, the rising howl of the engine note, the knowledge it’ll keep pulling beyond 8,000rpm and anticipation of the next upshift all setting neck hairs to attention. Drive this car properly and the rewards are easy to appreciate, the delicate blips required to smoothly navigate your way up and down the box adding an inspiring soundtrack to a driving experience already brimming with intensity. It’s the kind of car where acceleration figures and other stat-based bragging rights just seem totally irrelevant. Gorgeous to look at, demanding to drive in all the right ways and yet simultaneously approachable and fun – it’s everything you’d want in a Ferrari. With a sense of race-ready toughness you don’t get in the original.”




    https://www.roadandtrack.com/car-culture/a28309552/ferrari-f355-modificata-jeff-segal/


    The race parts sharpen the car, but the magic sauce here is the suspension. Segal sank a lot of time and consideration into a car whose nose "pushed like a pig" from the factory, turning it into something both responsive and livable. Nearly three years of tinkering has led to this spec. "Maybe it's done. Maybe it's never done," he says.

    "There's this misconception that a track car has to be stiff and harsh and brutal. That's not the case. When you look at some of the most dominant race cars out there—for example, the Corvettes racing in the GT Le Mans class… even the untrained eye can see that the Corvette is soft and very compliant but with enough control that it’s not sloppy."

    I had the Superformance Fiorano springs tested by Murray Coote one of the most respected suspension specialists in Australia.

    Elliott, use this guide to see how your choice of sway bars, and other parameters, will affect your car's handling...

    Thanks Barry. Definitely wanting to go for less under steer. Already the damper ecu and the Fiorano springs it’s much more pointy and responsive.

    Elliott, at certain open track events I go to I have the pleasure of sharing the track with racing teams. Here I am a year ago at Watkins Glen International...

    I have 2 cars setup totally different the way understeer was handled.

    One was put on Jenny Craig diet and has a huge splitter, full undercar ground effects.
    Other has fuel moved up front in a cell.
    Both share very similar weight distribution but handle totally different.
    I really like the fuel tank up front I can pretty much plant the nose.

    I reached out to TPCracing.com about them making a DSC suspension controller for the F355. I had one in my Porsche 997.1 turbo and it made a dramatic difference in how the suspension felt with sport on and off. So much more compliant and stable. They make the controller for many brands. Im sure that they could make custom maps that are probably better than the FHP ecu. It would likely require a group buy. Check out the tech. https://www.dscsport.com/

    I wholly support this and would be in. I have used their products as well and really think they do an excellent job.

    For whatever it’s worth @Senshi458 says his FHP 355 has better steering than his 458.

    Anyone who installed just the rear FHP / Challenge sway bar care to weigh in on how it went and a review? Just got my bar from eurospares and looking forward to some feedback.

    I think we are a lot in th same way. I béguin to have a lot of FHP parts

    Steering rack
    Brake discs
    Yellow pads
    Front and rear Roll bars
    It stays Ecu but i'm on a good way, from a Fhp ecu, someone can reflash my one, and the 4 springs.
    My question is …superperformance or Eurospare sells some FHP springs with the good number part ?
    Are they enough ? Quality is good or not ?
