So the membership has convinced me not to have my rear brakes done by the dealer, due to exorbitant costs and possible upgrade in the process.
I have a 2017 S with super performance (non ceramic) brakes.

Want to ask what everyone has used for rotors and pads and if they are happy with them? ( no squeeling)
Where you purchased and approximate costs would also be appreciated.

And lastly, ceramic pads vs carbon metallic?

Thanks to all for their input and opinions!

 

As mentioned elsewhere I have Hart brand after-market drilled and slotted rotors and Porterfield R4-S pads and no problems with either.
I bought the rotors about 8 years ago for my old XFR then swapped them to the F-Type, not sure they are still available, but a few here have fitted pretty much identical R1 Concepts rotors and are happy with them.
The Porterfield R4-S pads are not ceramic they are carbon/kevlar but they work the same as ceramics - smooth, quiet, progressive, low dust but a bit slow on the initial bite (which I prefer - not as grabby in stop/go traffic as the OEM pads). The only true ceramic pads I know of for sure that fit the super performance brakes are EBC, either Redstuff (street) or Yellowstuff (street/track), and they also get good reviews. Another possible ceramic pad is Dynamic Friction 3000 Ceramic per the Rock Auto listings, see here: https://www.rockauto.com/en/catalog/...brake+pad,1684.
Hard to tell which ones are 380 mm front and 376 mm rear but definitely not the ones shown as "silver brake calipers" as that undoubtedly means the base 355 mm and 326 mm brakes. No reports on them that I know of as yet but they seem to be a reputable company so worth a try.
The OEM pads are semi-metallic (not "carbon metallic") and they are dusty as hell and can be graunchy/squealy, you definitely want ceramic or Porterfield R4-S if you want low dust and low noise.

 

I have geocoated drilled and slotted rotors (bought primarily for loos since the discs are huge) and porterfield pads. Looks and works awesome. Hated the high dust from factory pads and I was lowering the car on vap coils and adding spacers so I did the brakes and rotors too.

 

Those rotors look great with your wheels!
Do you remember the manufacturer and approximate cost?
Thanks again

 

Don’t recall the cost, but they are made by R1 concepts - geomet coated. I painted the vents etc black.

 

I have the same R1 geomet coated rotors and Porterfield pads. I had no issues with either and a very simple install. I got my rotors when they had a 30% sale. They run 25% and 30% off often. I think the rotors and pads total ran me around $600. You will want to replace the sensors at the same time. One of mine broke during install and thankfully the local Auto Zone had the sensor in stock.

 

How did you prep the rotors before paint? What type of caliper paint?

 

Are the pads R4-S?
They have about 4 different choices for the super performance brakes. Possibly different compositions?

 

Correct-I think that was the consensus of the group. I have the R4-S and no issues with squealing and minimal brake dust. I originally was just thinking of getting rid of the OEM pads since the dust was insane and decided to upgrade the rotors as well since I am there.

 

How do you know what size you need? Looking at firestone, they had 3 different sizes, and that could matter for the width too? like vented, or not etc?

 

How grippy do those brakes feel? what about spirited driving vs cruse along? daily driving vs track?

 

Width should not be an issue but you will need to double check the diameter to make sure you order the right discs. I have the larger rotors on front and back so it was easy to match them up - the brakes were a different story - I initially received the wrong rear pads, had a new set overnighted, and they were also wrong, come to find out the second set was the wrong pad in the correct box, so the third set arrived with the correct box and contents.

 

I have R4-S with new rotors and think they are the only way to go! Unless price is a big factor.

 

Which rotors did you pick up?
I need a set this week, mechanic said slotted/drilled more likely to crack?

 

It's only drilled (slotted or not) that are more likely to crack and even then only on the track or maybe if driven very hard on a twisty road for an extended period. Perfectly OK for normal street/road use.

 

I know everybody loves the look of a drilled rotor and quiet, dust free pads. However, as a very enthusiastic driver, I always prefer the old school performance of a quality solid rotor and Carbotec XP8 pads or very high end semi metallic pads. I avoid typical ceramic brake pads at all costs due to the relative lack of performance and despite the claims, I don't find most ceramic pads to be as good as they claim. Most brake pads have a friction rating like FF or GF and this can be a great place to understand what to expect. (cold and hot friction) But unfortunately, with the common Chinese pads now, the ratings may be inaccurate. I only believe the brake friction ratings from very reputable companies. For what ever reason, I prefer a pad with a little less initial cold bite, but one that warms up quickly and provides fade free performance on spirited drives or amateur track days.

I'm not sure if anyone here uses Carbotech pads, but I really like them.

 

Thanks for your input, I went on their website but they only list the 325mm rear size rotors, and mine are the 378mm, and I assume the pads won’t fit?

 

Correct, 326 mm and 376 mm pads are not interchangeable.
If you are talking about Porterfield R4-S then for the 376 mm rear brakes you want AP 1753 see here: https://www.lpiracing.com/store/pc/s...2&iPageSize=10

 

Many brake companies will produce a brake pad for you. The backing plates are simple enough to make, and the pad material is common. I've asked Carbotech to make pads for my truck and they did!

Here is a handy chart to compare the friction rating and the CoF. My fav Carbotech pads, the XP8's are 0.56 or H rated when hot. By way of comparison, an F rated Ceramic pad could be rated at 0.36 and have about 40% less stopping power. That's a huge difference.
