Hi guys,

I have been getting myself up to speed as I am about to pull the trigger on a 2016 gts. From all the reading I have done, seems like brake cooling is a weak point. I also saw that the new gtr pro has some nice looking brake ducts that look like they could be retrofitted to other amg gt trims. Has anyone tried yet?

Thanks
David

I was at my MB dealership last Friday trying to see if I could find out any info on these ducts. Nothing currently in the USA as the Pro isn’t in their system yet. Plus you will probably need the VIN of an actual Pro to be able to buy a set from what I was told.

I have a sold Pro sitting at my store and I made a request with my parts department. I should have some news tomorrow or Tuesday... in the mean time change your brake fluid to something with a higher boiling point, and install titanium backing plates so you can recover faster... cheers!

DriveAMG

I will have part numbers to post shortly...

Awesome! I'd be interested in ordering a set as well DriveAMG so looking forward to your report. Did they give you a price on the ducts? Do you know if it's possible to purchase the gurney lip on the rear spoiler from the Pro as well? Not sure if they would include that as a separate part or as part of the entire rear spoiler.

is definitely a separate piece that appears stuck on as it actually has some play in it versus the rest of the wing. However if you look at a stock GTR there is already a bit of a flap built into it along the edge just not as severe as the stick on one on the PRO

nrgy

Ah yes you are right. I'm expecting my GTR to arrive next week hopefully so don't have one in front of me. But already planning ahead with some tweaks. Thanks for the photos!

The PRO wing does not have the same range of pitch as the regular GTR, I think that is part of the reason the Gurney flap was added. At the max position, the PRO wing is still relatively flat.
I was a bit surprised the other day when I was adjusting it.

Sweet! You picked up a GTR!! Can't wait to see pics (and lots of them!) and the development of your mods.....always tasteful and perfect!! Congrats...

nrgy

Thanks Zephyr! I struggled for the last few months deciding which car to go with but the GTR just seemed to tick most of the boxes for me. Super excited...I went with the Hell Green after having conservative colors with the last two cars. Only option missing is the CF I exterior. I'll try to get some nice pics to post, but of course you can just go look at yours in the garage lol! I still love silver on Mercedes..is that a mango paint on yours? How often do you drive your GTR?

ZephyrAMG

Great color, excellent car! Congrats! The entire GT line is magnificent in so many ways. Such a great performer all around. And its stunning from the inside and outside. The build material quality, the warranty, the performance, the price, the power, the interior.....all these factors in relation to other cars in this market category, the GT wins. There are a few other cars in the same class but I think the GT wins overall. I have Irridium magno. I have the carbon 1 and 2 package and on a lighter car, even a metallic paint, it stands out and looks athletic. Carbon is fine but to some extent, with so much trim getting carbon, it's sort of getting gimmicky. I just don't have CCB. I drive it all weekends because I can't stay away.

Congrats again...!

Any update on the brake duct part numbers?

dyc1077

Curious if you were able to get the pro brake ducts?

DriveAMG

I wasn’t able to get them to fit.... I didn’t really have too much time but I’m the 20 min or so I played around with the parts I couldn’t see how they fit... sorry for the delayed response. Been busy...

I know it is possible to fit them on a GTR. I am not sure about a GTS

In workshop I have a gtr, gts and I got a PRO couple of days ago... one of the first things I was curios about was the brake cooling and I was suprised/confused/disappointed. So let me first answer the question: YES it will fit a regular gtr and any gt... You just have to cut and remove most of the aluminium heatshield using hobby tools and fasten air guides with some cable ties. But it isn't worth the effort as it is NOT much of an improvement. So I was left wondering how is it possible that AMG did that kind of engineering? What they made is actually not a duct, but an air deflector. I guess the idea was to deflect the air towards the rotor where they removed practicaly entire heat shield and have the rotor suck the air. But I see couple of problems there: 1. Air flow in the wheel housing is completely chaotic so any kind of air guiding device isn't really gonna work. 2. Wishbone is in the middle of the U shaped air guide leaving just couple of millimetres for air to go around it. 3. I explained this on another thread already: It is good to separate the air coming in to the heart (intake) of the rotor from the hot air which is being blown out of the rotor vanes. By removing heatshield You let more of the hot exhaust air to come back to the intake...

What are the part numbers for these brake cooling air deflectors from the PRO?

Can you share pictures of the whole duct? Interested to see other things that can be done to make them work

Draptec

I can't, we already took them out and installed the TIKT brake cooling ducts. We wanted to do some comparison tests as we did with TIKT vs stock on GTR but we had no time as the car had to go to racetrack and we needed brakes to work in order to test other aero upgrades...

Btw. I'm not optimistic that anything can be done to make them work. It looks like it was made just be made and to appear upgraded regardless of its actual effectiveness.

I just ordered the brake ducts from Renntech prior to the first time taking the GTS on track. Would be a shame to burn the rotors.
I also have the diffuser, side rockers and front splitter from them so it's always cool to be able to stick with the same brand.

As soon as they start shipping their cage it will be installed also.

Has anyone successfully retrofitted the pro brake ducts? Can't seem to find a complete picture how they come together. I believe there's a defector on the steering rod and then one on the control arm. Any insights totally appreciate.

might want to consider these.

Until someone can provide real-time on-track rotor temp data via a video overlay (like TiKT has done), I wouldn't buy any brake-cooling product that's in a deflector format ... because I highly doubt they'll be very effective (and that includes the hokey deflectors that were on my GTR Pro, now replaced by TiKT ducts).

Good brake-rotor cooling requires a significant air-flow that's able to be injected into the opening in the inside/back center of the brake rotor so the air can travel through the inside vanes of the rotor. The higher the volume/pressure of that air and the more it can enter the center of the brake rotor -- without leaking around the edges (or through pass-thru openings in the center of some 1-piece rotor designs) -- the better the cooling. I don't see any situation where deflected-air cooling will be as effective as a strategy where the air is gathered (and, ideally, pressurized) and carried via some enclosure (duct tube, plenum) in a manner where it can effectively feed the inside center of the rotor with minimal leakage.

I make these statements based upon having spent a considerable amount of time installing various versions of brake-cooling ducts on a C63 S and taking rotor-temperature measurements at a short/technical track that's brutal on brakes (though they were only static/pit measurements, not while-running measurements) ... which is just to say that I have at least a little practical experience with this.
