355 Fiorano Handling Pack Brake Pads

355’s equipped with FHP came with upgraded brake pads. They are Pagid Yellows. I’m not sure if they are RS19 or RS29, but my guess would be RS19. Can anyone confirm?


Also, 355 only lists a product code for the Fiorano front pads, but not for the rears … or at least I can’t seem to find it. My question is, are 355 Fiorano rear brake pads also Pagid Yellows?


I decided to go through pics of the recent Serie Fiorano on BAT and noticed the rear pads are indeed yellow. However, it is hard to know with certainty if those came from the factory this way or put on after. I went through all the receipts and could not find any indication of the pads being changed (front or rears), which is odd for a 40k+ mi car.

Interesting to note, when you buy an FHP front caliper new (176017) , it comes with Fiorano spec Pagid Yellow pads included. However, this combination offering does not seem to exist for the rear. Odd.

It just seems to make more sense to me Ferrari would/should equip the FHP 355 with the same front and rear Pagid pads vs just Pagids in the front and standard Brembo pads in the rear.

Thoughts?

You learn something new everyday with these cars


Both FHP front and rear pads are indeed Yellow.

Here are the part #’s:

Front pads - 70000910 (Pagid Yellows) <— I’m
Still not sure if it is a pure Pagid or a Pagid/Brembo. Also need to find out what Pagid it is.



Rear pads - 70000882 (Pagid/Brembos Yellow RS 4-2-1). Same pad as 456 GT rear.



What threw me off is the fact they are Brembos, but ALSO Pagids. At least the rears are. I still need to confirm the fronts.

So I know the rears are Pagid RS 4-2-1’s , not RS19’s or RS29’s.


Here’s an old post from Martin Meade, who seems to be one of the key guys at Giro Disc.

https://www.ferrarichat.com/forum/threads/opinions-on-best-brake-pads-for-f355.40861/page-2

“******** has Porterfield R4-S pads for $89.00 an axle (F355) with free shipping until the end of the year. We recommend the Pagid 4-2-1 compound as the ultimate street/track pad, but they are spendy($150). Ferodo DS2500 is excellent as well but they do dust more than others($135). Either will have higher temp limit than Porterfield. www.********.com


Thanks,

Martin”



I honestly don’t think he knew the 4-2-1’s were FHP pads when he made that comment in 2004.

 

They even come in a Brembo box.

“The most popular brake pad for street cars is the Pagid RS 4-2-1 Black. The high performance compound with low fading characteristics and high cold friction. The RS 4-2-1 is a most comfortable medium friction compound and very easy on the discs (rotors). Very popular for brake up grades or tuning. It is OE on various Super Sports Cars among others Aston Martin, Bugatti, Ferrari, Lamborgini, Lotus or McLaren. Suitable for street and light track use such as track days or driving education.”

 

RS 4-2-1 Yellow might be exclusive to the 355/456 GT.

PAGID Friction Compounds

PAGID racing compounds are complex formulations with very high content of ceramic materials. All Pagid materials are asbestos free. The difference to competitor’s ‘metallic’ compounds is the superior thermal insulation and the higher heat resistance of ceramic compared to iron. Ceramic has, to the contrary of iron, very low heat conductivity. Consequently less disc (rotor) temperature goes through the pad into the caliper. We measured up to 60°C (140°F) less caliper temperatures with PAGID pads vs competitor’s pads. This is very crucial when it comes to brake fluid boiling.



PAGID friction compounds, especially the color-coded yellow endurance materials, have a very low wear rate and are extremely discs friendly. This fact is proven by numerous race wins in 24 hour races world-wide. Brake modulation and pedal feel with PAGID pads are excellent. Consequently it is not only less likely to get (tire) flat spots but also drivability is better.

 

@Senshi458 How’s the squeel/squeek on your FHP pads?

 

I test drove my car some days ago, as the weather was some better in Norway and was after to hear squeel/squeek but not that much. I run PAGID pads on my Porsche and they squeel/squeek a lot. The 355 sound of squeel/squeek is almost nothing

 

I’m going to assume these are still the same Pagid Yellow pads originally installed on the car? How many miles on the car again?


And which exact Pagids do you run on your Porsche?

 

In your opinion, do you think Ferrari made an excellent choice using these Pagid pads for the 355?

 

I really like the Pagid brake pads and think Ferrari did great choice using Pagid pads.

I run this set-up on my Porsche 911
Front: PAGID Pad set 2474RSL29
Back: PAGID RACING BRAKE PADS RS29

I will check on Ferrari to see if still yellow Pagid pads, my 355 have 48k KM, I think thats 29k miles

 

Update:

Front and Rear Pads are Pagid/Brembo Yellow RS 4-2-1 Pads. They are both sized U-1202 (Pagid dimensions for F355). Fronts are 17.4mm tall and rears are 16.2mm tall. Minor difference, so I think fronts and rears can probably be used interchangeably. I've ordered front and rears and they should be here in about a week. Looking forward to the FHP experience.

 

The Factory chose great pads for the FHP.

I upgraded my stock 951's brakes with StopTech slotted rotors and Pagid PORSCHE 951 944 turbo brake pads RS4-2-1, U1202 (Black). You'll be pleased, Ken.

I spoke to Martin Meade of Giro Disc a few days ago and he mentioned Pagid has discontinued the RS 4-2-1 line, meaning most of their stuff is now on the aggressive side. I haven’t confirmed the discontinued part elsewhere, but he now feels his second recommendation (from 2004), Ferodo DS2500, is the next best comparable although they dust more.

I’ve only used Ferodos on my other cars, never a Pagid. I’m curious to how good of a choice Ferrari made in 1998 . Can’t wait.

 

Some pics of front and rears provided by sellers. I purchased from two different sources as I’m a deal shopper .

Ken, I upgraded my Porsche's brakes in 2016. New Pagid RS 4-2-1 pads are available at ALCONKITS: Pagid Black RS4-2-1 P Type Brake Pads

Call them and see if they have yellow (I think Pagid only comes in black) U1202 pads or get the Pagid/brembo pads you show above.

Barry

 

That’s good to know Barry. Could be alot of old stock left out there.

 

There just might be some old stock Pagid/brembo yellow pads around. Check eBay.

Otherwise the new Pagid RS4-2-1 blacks will yield the same braking effect. You can always paint them yellow.

 

By the way, slotted rotors are a better choice over cross-drilled rotors. None of the F355 Challenge cars on the track today have cross-drilled rotors. They've all gone Gyro Disc slotted.

 

Like so...

Cross-drilled rotors had the tendency to crack...

During the Challenge Series, racing teams complained bitterly about frequent cross-drilled rotor failures.

 

For extreme uses, drilled isn’t the way to go. A slotted or Brembo Type 3 style would be best. For non-extreme use, drilled should be ok as long as it’s made by a reputable brand like Brembo. GD rotors is a notch under Brembo quality given the same design, but they are fairly priced.

GD doesn’t recommend drilled although they’ll do it if the client understands the risks.


Here’s a good link by Brembo.

https://www.brembo.com/en/company/news/disc-drilled-or-slotted

“Who is the drilled disc for

For those, on the other hand, who do not expect to subject their brake discs to extreme operating conditions, the “drilled disc” option is preferable because one of the benefits of this version is that it provides greater cooling capacity.



Both the drilling and the slotting are designed specifically to guarantee superior heat dissipation compared to standard discs. Nevertheless, the presence of holes implies greater heat dissipation capacity during braking than that guaranteed by the slots that characterize the slotted discs.





The Brembo Xtra discs could also be better suited for those who are more attentive to the aesthetic side since for most enthusiasts, the drilled disc is synonymous with sportiness.“

 

^

And I agree with this, Ken. As long as you don't use your brakes to the extremes we do on the track, cross-drilled rotors are perfectly fine for even sporty driving on the roads.

Several years ago I did see the damage caused by an original cross-drilled rotor on an F355 Challenge that fractured on hard braking on its way into a 90 degree turn. Damage to the right rear quarter of the car and parts of the engine bay was extensive. Those original cross-drilled rotors, the same used on F40s, were a big problem.

Pads are in. Brembo/Pagid Yellows RS 4-2-1 front and rear confirmed.
