Finally finished Brembo caliper upgrades from stock 2022 GT-Line

[NYBIOMED]

Wow, trying to gets the seals and dust boots were quite the challenge, but finally got the rears done, feels GREAT. I also had the 2-pt mid/rear chassis brace installed from Ultra Racing. It's also nice to be running my 3 season 19" tire set and putting away the snow tires until next winter! No fancy 2pc floating rotors for the rears, but the DBA 4Ks will be fine...if only the Apex package was available for 2022s, oh how much dough would've been saved...

How’d you end up sourcing the seals?
I’m considering going blue or gold with mine.

I Googled and made phone calls forever, in the end these guys came through:

www.stockwiseauto.com

Rear caliper dustboots/seals: Centric 143.34030 Disc Brake Caliper Repair Kit. $4.86ea
Fronts: Centric 143.63003 Disc Brake Caliper Repair Kit. $21.92ea

Of course, you will need to order x2 of each F/R

I also placed an order through Summitracing, 6 months later they showed up in the mail, after I forgot to cancel them, so I actually ended up with a spare set for the fronts. I suspect supply chains have somewhat caught up, so you may have much less difficulty than I did.

Thank you for providing part numbers!! I tried to find it once, without any luck. Will be ordering it soon, and getting my calipers powder coated in gold. Edit: just ordered front and rear sets.

Thank you. Much appreciated!

Hi. I own 22 GT line as well. And I am currently looking for brake upgrades. Could you please list the parts and where you got it? It is hard to get support for 2.5T. I am currently thinking about going OEM Brembo Calipers and 3rd party discs and pad. I am new to car parts, so I do not know where to start. Any suggestions?

If you go up in the thread, he lists the links to where he got the parts.

Thank you for the reply.
What I want to know is:
what size rotor did you use?
Does it compatible with oem brembo calipers?
isn't 3.3t rotor interferes with dust cover?
if so should I replace with 3.3 dust cover?
is break line fit with oem brembo calipers?
I am newbie to tuning so it is hard to determine which info is right for me.

Everything from the 3.3TT will swap right into the 2.5T, this is not true regarding dust shields from the early 2.0T. I purchase new SS braided brake lines, they are relatively cheap, so you might as well.

NO MODIFICATIONS NECESSARY, easy swap.

Thank you for your reply.
I may purchase dust covers or if replacing them is hard work, I will just bend them little bit to make it fit.
Thank you so much

Would love to see how they came out. If your up to it, post some pics

Yes I will !

Front dust shield on my 2.0T fit the larger Brembo rotor just fine. The rear dust shields, however, did not. I just bend them to fit when I first installed the Brembo calipers. Later, when I swapped to an LSD (from a G70 6MT), that was the perfect time to R/R the old dust shield with a set (from 3.3T) I bought off one of the OEM parts supplier.

It is a lot of work. You have to remove the 1/2 shafts, then disassemble the drive hub and drum brakes. You'll have to decide if it's worth it just to R/R the dust shields.

I think this is true for the early 2.0Ts- as they had smaller rotors, I'm not sure whether it was 2020, when they were enlarged- closer in size to the Brembos, therefore there should be no clearance issues

Maybe starting with the 2022 refresh? I don't know why they didn't do that from the get go. The slightly larger rotors likely didn't cost them all that much more.

I know that when Genesis dropped the Brembos on some later model year 3.3T G70, they kept the same rotor sizes. A '22 G70 3.3T owner that upgraded to Brembos found that his OEM rotors are the exact same sizes as the Brembo rotors, so the Brembo calipers fit right on.

Thank you for the update, especially work procedure. I have to think about it. Just in case I will follow the same path as you, could you tell me the part numbers? was it 58251-G9550, and 58252-G9550?

And the LSD part, how is it? was it worth it? I believe stinger sends 30% to 40% of the power to front if it detects slide. so in rear it is about 200hp only. I think that is the reason why they did not put LSD on AWD model.

Correct. These are the exact parts I ordered:

58251-G9550 Backing Plate $55.29
58252-G9550 Backing Plate $55.29

Some AWD Stingers did come with LSD. The Indigo Edition, for example. Might be others too. Even with AWD, having an LSD still helps with traction management and keeps the chassis stable under power. Mine's RWD, so to me it's a must have for AutoX and Track Days. For everyday driving... probably not.

So then what benefits do the Brembos offer over the stock non-Brembo brakes?

I would have thought that's rather obvious, but maybe not to some.

Instead of a single piston where the entire floating caliper moves, a fixed monolithic rigid caliper driving 4 pistons reacts faster to driver input and applies brake pressure far more evenly, resulting in more linear braking power and better pedal feel, as well as more even temperature gradient across the pad area, reducing hot spots and the associated brake fade.

Pads will also wear more evenly. Larger brake pads also increase overall thermal capacity, allowing for even less brake fade when pushed hard.

 

[NYBIOMED]

I can only tell you, my braking setup is the best I've personally experienced, with the exception of a 2008 Porsche GT3 I once drove. Albeit, I've NOT driven a lot of premium sport cars (i.e. Corvettes/BMW M3s/Mercedes C63/Audi RS 5 or 7s) I have also never driven a stock 3.3TT, as I have premium rotors/pads and SS brake lines over stock, so I'd imagine my setup is likely a bit better...just saying, it can always get better and indeed does.
