Brake pad deciphering

[MerlintheMad]

Are you going supply us with more details? Sounds like it could be interesting, and instructional.

However, if the calipers are same as on another car, why not positively confirm this and have the full range of pads for that caliper to choose from?

Because the pad shape and size (and caliper) are not the only important aspects of a brake pad.

As already noted, there are weights on the Kia-specified Stinger pads that are used to provide vibration damping specific to Stinger requirements. While it's absolutely possible that pads specified for Evos/etc will fit, they may not be "right" for the Stinger use case. The compound may also differ for this requirement vs others.

There is not "a compound" to these other pads you are referring to. There are different degrees of compound. Go to the Khartunerz site, you can get everything from mild street daily drivers to race track compounds and in between. From $65 to several hundred dollars. There is not a specific compound that is right for the Stinger, there are choices depending on driving styles ,Track vs non track, etc.....

You are correct about the weights. I put on Gyrodisc pads and so far no noise without weights. You guys holding off are just delaying a fix to the vibration issue due to nit picky semantics !!

I think it is funny when someone quotes my post and tells me stuff that I myself have already posted and said. Anywho, it remains to be seen if the weights serve any other purpose than noise abatement and @itguy61 is correct about compound selection. Choose the one that meets your needs. Personally, I am using the available aftermarket pads after tons of research and the comments here on the forum because the stock ones on my car (and others) are garbage. I chose a new pad compound that others have fitted to "grand touring" cars in the same or higher weight class and with a feel and stopping power that matches my driving style.

I quote posts to ensure it's clear which post I am replying to, no other reason.

I am with you - I am happy to use other pads as well. But you asked why pad manufacturers and/or resellers aren't selling many of the other pads they have in the same size as Stinger pads, and this may be a reason why.

No luck finding a rear pad for the car?

 

[itguy61]

Nick from Khartunerz has stated there are rears coming later this summer. I don't know from whom but I would suspect some of the same brands they currently carry fronts from.

 

[Hydrajin]

Centric has a rear pad stated on their site but tis nowhere to be found for purchase.

 

[MekstingerGT]

So wait are those silver tabs "weight reduction " thingy transferable to the new pads? I really like the look of them makes them look like claws lol.

 

[Tonkabob]

Thanks so much for the info! I will order one of the rubber adapters for my hydraulic jack and use those and lift a few inches behind the jack point .

Thanks,
Tim

The adapters don't work as there is plastic shielding in the way. Just jack behind the jack point and then put the stand at the jack point once lifted.

I looked at the akebono site and the same pad number is used on several different cars with Brembos. Cadillac, Ford, Mitsubishi and Subaru models with Brembos use the same model number pad. I think the folks waiting for a part number that is specific only to the Stinger are going to be diappointed.

Same thing for all these pad makers, the same part number for numerous models that use this caliper. I wish I had known this I would have tried the Akebono pads.

I held out as long as I could and ended up going with the StopTech performance ceramics. I saw no sense in continuing to ignore the conventional wisdom regarding "alternate" fitments when it came down to missing out on new rotors on the dealer's dime. I'll try to report back once my Stinger is back in my driveway and the brakes have been bedded in. BTW, I'm inclined to agree on the Akebono pads. I hear nothing but good stuff from user reviews.

 

[itguy61]

I look forward to your report. I am very curious as to how the pads you bought compare to stock.

 

[ehb5150]

So I can't find any evidence that hawk or stoptech makes pads for the stinger when I use the part numbers on khartunerz website. I understand that they took the time and effort to measure and cross reference the pads to another vehicle that uses the same caliper as the stinger....hence they are the only folks that have pads available for sale for the stinger. I'm not going to ask them what is the other vehicle, since I understand they are running a business... but I feel as a community we can figure this out also and then be able to buy pads for a fraction of the price from any brand we choose. So....who has a digital caliper and is willing to take measurements of their brake pads? Because I guarantee you that the brembo caliper on our stinger is not unique, another vehicle has been using it....for years...

CarID shows Powerstop ceramic rear pads (Z23-1284) for this application, so I ordered them. Wrong part. The application they show is for floating calipers and there's no accommodation for the slide pins.

Those could be for the non-Brembo Stinger models.

Our rear calipers look alot like the Evo caliper, has anyone ever measured the width, height, and thickness of the rear pads? The if the dimensions 86.6 x 63.5 x 14.1(14.1 or thicker), we can use the Evo rears too, not just the fronts.

Oh and for anyone in doubt of whether brembo made these from scratch or Kia just stuck on an already developed brembo; yes these are used on many other cars. Research, development, and testing costs too many millions for brembo and Kia to justify making a unique caliper for the stinger given the return on investment, simple business rules. How many stingers did they anticipate selling? Probably not many given it is a Kia and costs way more than majority of Kia's customer base would spend on, or will ever even seek out in, a car (point a to point b economic car).

Sorry for the mini rant but read several posts pointing to the same question/doubt with no clear explanation as to why it's not a new design caliper lol. All that being said, we need to just dig deeper into which other car has used the 2 piston brembo. As far as I can tell, it looks like a slightly updated revision of the Evo rear, just looks like they changed the overall external shape to save on materials or alter cooling properties or something of that nature.

I think Kia did specify a specific Ceramic pad compound for the Stinger.
Speaking of those pads, the stock pads are rated FG. I upgraded to the Euro Stinger/G70 pads and they are rated GG. This is quite good for stock pads. Care must me taken not to get a pad that’s actually less grippy than the stock pads.

I’ve been looking for another car that uses our rear pads. I’m getting very close to finding a suitable set.
Our dimensions are
Stinger Rear Pad dimensions

103mm wide /

73.56mm tall

14.8 mm thick @ 4K miles


Below, are the dimensions of the front 13.4 rotor pad from a Genesis Track Package.


The Camaro/ATSV rear Brembo pad comes close too




I’d still like to get a bit closer in dimensions before buying some cheap pads to test.
Volvo is my latest lead, there are some possible compatible pads there too. Not through checking yet though.

For anyone who's replaced their rear pads - Carbotech would love to measure them, etc, to develop their own custom rear pads for the Stinger. They already have custom front pad backings being laser-cut thanks to someone from here being kind enough to send along their replaced front pads:
Cquence group buy!!

Guys, I haven't read the whole thread but I see comment about the Camaro brake pads...I came from a 2016 Camaro SS with 4-pot front and 2-pot rears. I have my old brake pads sitting somewhere in the garage I believe.

Actually, I have my old 4-pot front calipers and Hawk HPS 5.0 pads for them sitting there too. Could any of those be used by you guys in your quest?

Can't see those images, too compressed and blurry.
Are those images from centric? I couldn't even select the g70 as an option their site.
