2.0t 320mm brake upgrade?

[Mkbruin]

Recently purchased a 2018 2.0t AWD and it’s due for pads and rotors. Non-brembo.

1) is there a way to tell if I have the 320mm brakes vs the 340mm without taking off the rotor to physically measure?

2) Assuming I do have the 320mm base brakes, what would be involved with going to the 340mm?

3) Brembo swap… do the Brembo calipers from the 1st Gen Genesis 4.6 sedans or the track-pack coupes cross reference to the Stinger/g70?

Brembo retrofit was the first mod I did on our '19 2.0T. Donor car was a Stinger GT. G70 Brembos are identical.

I think Genesis Coupe Brembos are also compatible but I'm not certain. 1st gen 4.6 no idea. Plenty of Stinger/G70 donor cars apparently, so really no need to cast a wider net.

I have stock everything from my 2022, brakes were actually quite good and If I knew then what I know now, I'd have prolly stuck with them and just put in the EBC yellow pads. LOW miles, excellent condition.
Taking offers.....

As far as I know, the mid tier brakes on the stinger are 345mm front and 330mm rear. The smaller ones are 320mm/315mm.

The way you can know is to look at the rear rotors. If they are ventilated, they are the 330mm. If they are solid they are the 315mm.

Another way is by checking what were the stock wheels. I am pretty sure (but not 100%) the 2.0s that came with the bigger brakes also came on 19" wheels.

Wow you have really delevoped a long list of mods.
I have always found the brakes on my 22 GT-Line to be more than adequate, I did however upgrade to ceramic pads and the stopping power also increased with less dust, she really stops on a dime as they say, to many hard stories on this forum about Bembro Brakes

For North America, all 2.0T and 2.5T came with 18x8 wheels. I'm pretty sure 2.5T without the APEX package have larger brake rotors. There was a thread on this topic recently. My 2.5T has the APEX and Brembos, so I don't have first hand knowledge on that. However, OP has an '18 2.0T, so none of that applies.

Personally, I subscribe to the philosophy that a car can never have too much brakes. In fact, I value stopping power as much as - if not more than - HP. If I could upgrade to C8 Corvette 6-pot front and 4-pot rear at a reasonable price, I'd do it in a heartbeat. This is especially true for a heavy car like the Stinger. That said, a lot depends on your usage case. Not everybody will drive in ways that exposes the stock brake's weakness or take advantage of enhanced braking power. So, that's up to the individual driver to decide.

The only problem with the OEM Brembos on Stinger/G70 is the OEM ceramic pads that most of them come with. Take that out of the system, and the Brembos perform excellently. Our '21 G70 6MT Sport came with factory Eurosport pads, which handled full-on track driving as well as both our Stingers' Brembos upgraded to EBC Bluestuff/Yellowstuff.

If the OP is wanting better brakes, the easiest way is to upgrade to more performance-oriented brake pad compound. For mostly street driving, EBC Yellowstuff has done well for me, but there are others like Hawk that are popular with enthusiasts. The downside is, of course, increased brake dust, which is almost always a accompanying effect of performance brake pads.

Changing from 320mm to 340mm might be a possibility, but that would likely require either a caliper mounting adapter, or different single-piston calipers. Highly unlikely that your current calipers would clear rotors that sit 10mm farther outward. IMO, getting that figured out is too much work. You might as well upgrade to Brembos at that point. Its a know quantity and opens you up for much more brake pad choices.

PS: I started with new rotors and pads. Also had the red Brembos powder coated bronze, so they were stripped and rebuilt using new seal, yet still get brake shudder returning every 5-6k miles before I need to go through the "cleaning" process of 6-8 hard 70-5mph stops, blah, blah...kinda annoying, which is why I made the statement "if I knew then, what I know now", I would have stuck with the stock 330mm fronts and just replaced with the Yellowstuff pads.
Besides, I cannot tell you the pains I went through to get the piston seals to rebuild the calipers during covid
In the end, it's pretty likely I'll never see another Stinger like mine.

I agree if you had to rebuild and refinish the calipers, that makes it a whole lot more work.

When I did my conversion back in 2020, I was probably the first to have done so. I searched online and didn't see anybody post anything about this retrofit. There was some talk on Genesis Coupe forums regarding OEM Brembo retrofit, but that was it. I looked up the Stinger online OEM parts microfiche catalog and confirmed that the wheel hubs (to which the calipers attach to) are exactly the same parts for both Brembo and non-Brembo Stingers. I knew with a high degree of certainty the calipers are a direct bolt-on replacement, so I took a leap of faith. Just so happened an ebay listing for a set of lightly used Brembos turned out to be local, so I picked up the set for $450 cash. The OEM brake pads that came on them were barely worn, so I knew the host Stinger was almost brand new when it met its early demise. The calipers were in beautiful shape so no reconditioning necessary. In fact, there was hardly a scratch on any of them. Below is exactly how the seller handed them to me.

Adding the cost of brand new set of rotors, and misc. parts and brake fluid, my cost was less than $800 total.

 

[NYBIOMED]

Oh wow, those were very nice indeed. The set i picked up off Ebay, were very good as well, just did NOT like the Ascot green with red calipers, alas the powder coating to match my bronze colored Aodhan 19's
PS: replaced the RTX Envy's, Aodhans much nicer and rotoforged

Just a slight correction, to avoid any confusion:
The front rotors on a Stinger can be 320mm, 345mm or 350mm (brembo calipers).
The rear rotors can be 315mm (solid rotors), 330mm or 340mm (brembo calipers).

Excellent, I have forgotten the exact numbers, thank you. I will go out on a limb here and state without scientific evidence, that the stock brakes on the 2022MY Stinger, was 80-85% as good as the Brembos and simply changing to high quality pads alone would split the difference further....without any brake shudder. I would NOT do it again, or recommend it at all, for a daily driver.

 

[Thebong24]

Just sharing mine upgraded last month got it in pick up parts for a steal 300 all 4 calipers. I just have to cut the brake dust shield in the rear.

 

[Volfy]

Love seeing more Brembo retrofits. $300 for all 4 calipers is a genuine STEAL!

 

[Thebong24]

I almost pulled the trigger Ebay 600$ when suddenly I realized maybe i will check my local pick up parts and they have a wrecked GT Stinger lol the break down was 80$ each front calipers and 60$ each rear

Nice deal, if the rotors were in good shape and low miles, should've grabbed them too. IDK, the 2022 GT-line brakes were pretty good and I didn't suffer from brake shudder, like I do with the Brembos, but I also didn't have them for too long...I don't see reports around here of it tho Trying to wipe them clean is annoying, usually doesn't work the first time, I don't always have the bandwidth to perform...yeah
