I have a 17’ QV. needed brakes all around. Alfa dealer cost for OEM was $4,500 plus tax parts and labor (I’m in Toronto, Canada). Found a performance shop that recommended giro disc rotors with posi quiet pads, all in cost with tax was $3,500! A substantial savings for an upgraded set up. Had it done in November and it’s just finally getting nice out here so I don’t have much of a performance opinion yet. Over all feel is noticeable for sure. And they look fantastic.

[@autofanaticcars]

Thanks for sharing and yes dealers are crazy thats why i show all the DIY on these cars on this channel to help owners out because doing a brake swap is literally 2 hours of labor. Also nice to see your limited use with the Girodisc you notice an improvement in the car overall. I could not believe how different the car feels just from the weight reduction on all 4 corners.

[@DavidPerez-zz1hu]

What was the name of the shop please. I'm in kitchener ontario. Thanks in advance.

[@HellzHonour]

I upgraded to Girodisc 2 piece all around on my Kia Stinger and I saved 8lbs in the front each and 5lbs in the rear each. I also shaved off 10lbs per wheel going to flow formed and it made a huge difference.

[@Koukiworld]

Love it man Thank you getting some today..... I did NitroR3 Coilovers and they react 3 times quicker... in long curves the car goes from leining to square squatting... Now I need to get these Ideal Race rotors off they are JUNK!!!!!!!!!! don't ever buy them

[@stephenlongfield8492]

I have just retrofitted a full set of new ceramic brakes on mine. Absolutely worthwhile and the best thing I’ve done to the car!

[@autofanaticcars]

what did this cost you and did you just put the rotors and pads or you changed the calipers as well? I was told the IBS module is different for CCB cars did you get yours updated or it seems to work fine as is? What year is your car?

[@stephenlongfield8492]

@@autofanaticcars it’s 2018 car, the calipers are different as the front ccb brakes are wider than the steels. Front set are plug and play. For the rears you need to change the rear hubs as the discs are 360mm instead of 350mm, the main caliper is radial mounted so would be easy to add a 5mm spacer but the Ebrake is lug mounted so no such joy. Message me if you need more details 👍

[@wojciechsobczak3247]

Hi i did exact opposite, changed crappy CCB into P&P Girodiscs, more than happy with this setup right now

[@steriledial]

@@wojciechsobczak3247 Out of interest, what did you do with your old ceramic discs?

[@Sbailey294]

You will feel this upgrade. I swapped my OE rotors for Girodisc on my IS-F a few years back and had planned to do the same on the Giulia. Turns out both cars also use the same front Brembo caliper. I can attest that my favorite part of the upgrade was the improvement in ride quality and the small steering feel improvement. Never had any issue with them - I can say the alloy is tougher than the OE brembo cast iron alloy; and the Porterfield R4S while still fine on the street do not bite as well. Girodiscs can tolerate a more aggressive pad material, and you may want to know that about them depending on your use.

[@Rsam86]

I’m about to order Giro and EBC red for my 2019 S4. I’m on a larger turbo so these should deff compliment the extra power.

[@clark724]

My qv came with CCB, I swapped them with girodisc because I track a lot. From my experience these rotors paired with race pads has about the same stopping power as the CCB. It does make the car a bit slower (some 2-3 miles too speed on the straights), but I don’t have 15k spare money to throw after perhaps 20 track days for carbon rotors. So if your qv has CCB, this is a cost effective option, but if your qv has steel rotors, I agree with Phil 100% this is a highly recommended upgrade

[@autofanaticcars]

thanks for sharing your feedback with us all.

[@wojciechsobczak3247]

Same here :) trackdays kills those ccb's on Giulia really fast (not even mentoin ccb pad costs...), but it's not ccb fault... rather very bad cooling.

[@clark724]

@@wojciechsobczak3247 very unfortunate truth about cooling. The oem CCB pads lasted about 3 days on me, and they gets chewed up unevenly, which makes very bad brake pulsation under street braking pressure.

[@seankwilber]

Reducing unsprung weight made your car slower accelerating on the straights?

[@rosinor6406]

@@seankwilber he has Ccb so yes these are heavier than ceramic

[@genyosai]

This was one of the first modifications I made to my Giulia QV April of 2021, as it is primarily dedicated to track-use. The Girodisc CCM replacements and Raybestos ST43 pads are the best setup for my driving/track-style.

[@autofanaticcars]

loving the rotors so far i am finally getting use to the lighter front end

[@cannonsloan2783]

These look so much better than the swirly rotors.

[@autofanaticcars]

yeah for sure i love them so far

[@Vizenz121_OR]

I put them on my 03 SL55 and all the way around it saved 32 lbs. crazy

[@autofanaticcars]

thats huge weight savings for sure wow!

[@mrbryanmarshall]

Good, done several sets already of these with EBC blue, best combo.

[@autofanaticcars]

have you gone through the pads super quickly and have you replace the outer rings yet or your still good?

[@mrbryanmarshall]

@@autofanaticcars yellow stuff goes really quickly, blue is better but tough on discs. Pads last 3 or 4 shortish track days (blue) 1 or 2 (yellow. ) bobbins last about as long as the disc, but you get a new set with the outer ring order. So all good. I need to skim the front about half life, handles it well but they scratched the hub so ordering new complete fronts (basically 3rd set) and second set of rears very soon. I kill any discs very quickly. Car with tracking and blue stuff, this will be 4th set of discs front and 3rd set rear, I’ve done 50,000 kms since getting the car. (Also 10 sets of tires so………)

[@autofanaticcars]

wow you drive hard like I do except I do not track the car here. still scratching my head why the rear EBC Blues have not bedded in better as i show in my video here.

[@mrbryanmarshall]

@@autofanaticcars rear will take a long time with blue. I actually think it’s over brakes with blue on the rear. I’m currently on blue front, yellow on the back as an experiment and it’s much better imho.

[@autofanaticcars]

@@mrbryanmarshall yes the issue is in the US is very hard to get stock on parts now still and the yellows were out of stock and i found the blues from some distributor who had one set left so i bought those and a set of fronts as well. i do not feel the rear being over braked so far but maybe as they bed in more it might make the car nervous under hard braking in corners we will find out soon enough i guess

[@philipmonk5473]

Been looking for brakes for my QV and was considering the Tarox. They don't have a good rep here in the UK. Import for these GiroDics makes them very expensive unfortunately so I have had to go OEM. :-(

[@westschleife]

Doing this upgrade right now, thanks for the vid. Who did you go with for the carbon instruments binnicales?

[@autofanaticcars]

Koshi

[@westschleife]

@@autofanaticcars thank you, is there a good distributor in the US? Alfa9 only has a few parts.

[@autofanaticcars]

We order directly from Koshi in Europe too many fakes being sold all over the USA so be careful the parts turn green and they wont warranty them buy direct send them an email they are very open for international clients.

What brake pads u think are best for street/track

[@justobey733]

Phil are those billet steal rotors do you know ?

[@justobey733]

Are they good for every day driving

[@yoelsegal6254]

Great video! I just ordered the GiroDisc for my QV. I've had a bad time with my Tarox + EBC blue stuff as they start to vibrate at high temperatures. What do you think are the best brake pads options for the GiroDisc besides EBC?

[@autofanaticcars]

yes the vibrating harmonics of the Tarox really bothered me as i mentioned in this video

[@Suavemente173]

Love it.

Hi.I need help to change cylinder head micro filter alfa giulia 2.0 280hp q4.

[@rdrrua]

obviously carbon ceramic brakes trump these in most of the categories (weight, performance, temperature resistance, life under pressure / on track, etc)? or those were outside of your scope of review?

[@autofanaticcars]

my car does not have carbon ceramics and i do not know anyone with an Alfa that does but many who track their cars with ccb switch to the conversions Girodisc makes. the video was to highlight the weight reduction and changes to the car dynamically versus OEM and Tarox rotors

[@rdrrua]

@@autofanaticcars at some other giulia forum: Carbon vs Steel Rotors (each rotor): Front: 6.35 kg vs 10.88 kg Rear: 4.25 kg vs. 9.04 kg Total weight saving: 18.64 kg Tecnico wheels are approx 2.3 kg a wheel lighter, so an additional 9.2 kg saving there, totalling 27.8 kg weight difference in unsprung mass, which is the equivalent of around 83.4 kg / 183 lb of sprung mass!

[@autofanaticcars]

crazy i know plus my car has Sparco carbon seats which are lighter and not all the updates of the newer cars like fold down seat, thicker glass etc so mine is lighter than the newer cars. I had my wheels custom made forged and they are lighter than the OEM technicos as well. this chassis reacts to every single incremental change you make to weight unlike most cars in the sport super sedan segment because most are so heavy to begin with.

[@mrbryanmarshall]

Giros are second only to ccb. But, the cost with ccb is mental. Re weight, the technicos help, but they are actually under spec for the GQ. I’m speaking to a guy who designs the Ferrari F1 wheels who makes High end after market wheels, incl for the GQ, and he says they are not strong enough for the parameters of the car. This is evident with tracking, mine are starting to oval, seriously. Another customer’s ovaled and cracked, which mine are also going the way of. Temp on track. Open for discussion, I have high temp fluid, never had an issue after this. But, a friend with exact same set up as me (giro and blue) had a piston failure in one oft he callipers and was getting very odd wear and over heating, but calliper related, not discs I think.

[@stephenlongfield8492]

@@rdrrua great figures. I have just retrofitted the a full new ccb set onto my car and installed the technico forged wheels for the maximum unsprung weight benefit. I have also added the Sparco Carbon seats, but I have added the CWSM back to them to retain the heated seats and steering wheel so not likely to be any lighter now 😀

[@julianskns]

Have the same on my Mustang so worth the price

[@autofanaticcars]

very tempted to do these on the Shelby Gt350R if i keep it

[@julianskns]

@@autofanaticcars it honestly took me months to decide after looking at different options these are the lightest I found unfortunately they didn’t offer for the rear at that time not sure now but I was able to find something very similar in looks only those are one piece rotors aesthetics improved by just doing these GiroDisc for sure!

[@LorandHungary]

Hi , do you think the stock brakes are fine to stick with on a tuned QV? I am making 683hp , so i don't know if i should stick with them. Also, i live in europe , so we don't have all the brands available here.

[@mariuskukosh2562]

What mods do you have done to it?

[@mariuskukosh2562]

What did you do to your QV that it has 683hp?

[@transparentcare]

How long do stock steel rotors and pads typically last

[@autofanaticcars]

the rotors wear depending on the type of pads you use, some pads are very hard and aggressive and others are softer and less rotor wear. usually if the rotors develop any groves on the friction surface i suggest replacing them

[@74amills]

In my opinion I trashed two sets of front Tarox discs and will not be buying them again.

[@autofanaticcars]

thanks for sharing in my first video there were so many negative comments on the brand overall i was surprised myself to learn this.

[@saadameil]

I trusted the tarox brand, too, but they are quite bad. I spend more time having my brakes fixed now with tarox than actually being able to drive with good brakes. The tarox discs warp even while bedding

[@andretasca4374]

Hey Auto Fanatic how's the breaking performance at low speed with these rotors? is the Brake by wire "Problem" solved wiht that?

[@andretasca4374]

I mean walking speed..

[@autofanaticcars]

braking is incredible best so far in all the upgrades I have tested with braking in 3 years. the pedal modulation and feel is just not there because it is brake by wire but you sorta get use to that after a while.

OH- let me also add, be careful what you clean your wheels with…the Girodisc; The anodized aluminum hat can become discolored. I’ve used the CarPro or Sonax cleaners without issue

[@SlumRacing]

The OEM Giulia qv bigger calipers from the ccb are plug and play with your car. Buy a cheap ccb 2017 used car. Do a full switch and put their OEM non ccb brakes on that car and then sell the car. Haha JK. Also did you get a chance to read up on alfissimo new gta ecu upgrade for our car which makes the car if lowered drive smoother.

[@autofanaticcars]

I wish someone made a CCB rotor conversion aftermarket but it is such a small niche market and most track guys are converting to the Girodisc anyways as its more cost effective. the Girodisc is a substantial upgrade to these cars versus OEM and Tarox rotors i can not believe the changes it made to the car dynamically its so different to drive now/ i tried that ECM and it caused lots of fault codes with my Kw coilovers so I think there is a compatibility issue with my car and suspension. It also made zero improvements on my car I drove on it for 2 days and the car felt exactly the same as with the original ECM and switched it back. I was excited to see if it worked and made a significant change but my car is not a candidate for such.

[@tmw2442]

Have girodisc rotors on my 2016 Golf R with hawk hps 5.0s, I am getting a handfull of clicks under slow speed braking 15mph to zero and another hand full of clicking again on acceleration back up from 15...anyone have ideas or experiences like this? No noise during break in, but started after the rotor coating was worn off. kzbin.info/www/bejne/eXKTZnuaorKlrMk

[@autofanaticcars]

please re-torque your wheels this is common issue with noises on GM cars like the CTSV and Camaros and Vettes over the years the rotors are suppose to be a floating design so some low speed noise is considered normal by most manufactures.
