Installed the OEM Track Brake Ducts that came as standard equipment on my 2017 1LZ Z06 with iron rotors.
Kit consists of four pieces.
- Two "clamshell" pieces which mount around/encapsulate a portion of the leading strut of the lower control arm.
- A riser which attaches to the clamshell pieces directing air upward/vertical befor turning 90 degress towards the rotor. The outlet ends several inches inside of the rotor/spindle. If they extended any further I believe they'd hit the spindle while turning.
- A riser support bracket which attaches to the top of the riser and also serves as a deflector at the bottom directing air into the duct intake. This piece also adds strength as it attaches to the leading strut of the LCA.
Note I didn't install the wheel blockers as I ran out of time. I think I'll mount them and leave them on all the time even though GM says to only use them on track. I can't see how they'd do any harm.
The wheel blockers capture air coming from the riser outlet and directs it down and around the rotor and through the rotor vanes.
Also, you do not reuse the existing air deflectors mounted at the factory that you remove as the first step of the installation of the track ducts.
The kit is also 100% independent of the existing brake ducts off the grill which just dump air into the wheel well.
Only tool needed to install is a small torx socket or driver. Install of the first side took a little over an hour. The other side took 15 minutes. The instructions are sort of difficult to follow.... Not hard just have to figure it out.
It took more time putting this damn post together than it did to install the ducts....
FWIW, I've put 970 miles on the car in less than a week. Need to get to 1,500 to get on the track. I'll have that by the end of this weekend.
I do not have part numbers for the kit. I previously posted part numbers but was informed they are the numbers for the install instructions. BTW, the install instructions are in the owners manual.

I would think these should work equally well on a J57/CCM brake car. The blocker ring maybe not, but the duct would still direct air to the appropriate place. Now the front carbon rotors may not be designed to effectively take that air and send it through the vanes, but that is another story.
Wonder how long it would take to get my hands on a set of ducts from GM. I'm guessing it will be next year before they are available due to constraints/backorders, etc.

It looks like these grab air from under the car. Is it possible debris could be picked up by the duct and blown onto the side of the rotor? On an iron rotor that isn't an issue, however, with a fragile ceramic rotor the rotor itself might be damaged.

Bill,
As stated in my post and pictured these surely do grab air from under the car. The 4th picture in my post was taken with the car on the ground and the camera right behind the splitter. Basically, a head on shot of the intake at ride height. Debris will get in them but it might be difficult to get through the two 90 degree bends that exist before the rotor. No different than debris getting in the ducts catching air through the grill or like the ducts we used to run on the C6Z with the Quantum or LG ducts.
They will pick up/catch debris and restrict air flow or damage/hit the rotor. As such, I've already thought about putting a wide mesh screen on the air intake. Something that wouldn't restrict air flow too much.
All I know is they came with my iron rotor 1LZ car and I did not order them as an option.
Thanks. I've seen two separate threads on this nice "delivery surprise" but on the Chevrolet build it site for the 2016 Z06 they were listed under accessories.
BTW - the 2017 is now up on the Chevrolet Build It Site and they don't list these under accessories, so they are probably included on all 2017s.

I would be surprised if they came with "all" 2017 Corvettes. I imagine you were inferring all 2017 C7Zs?
I was thinking they would come with all dry sump engine equipped cars, however, a friend of mine took delivery several weeks ago of a 2017 Grand Sport and he didn't get them.
Found out some more info. The ducts are listed as an option for the GS, standard on the Z06/GS J56 cars and are restricted to cars MY 2016 and newer. That may mean there were more mounting holes or different holes drilled into the LCAs. Might be interesting to see if there is a difference in part numbers for the 2015 and prior LCAs and 2016 and later LCAs. There isn't anything about the ducts being made available as a separate kit or as an accessory. However, that could change after SEMA. There are no part numbers released yet.

LOL, I'm the guy that started the first thread you mention. I opened my big mouth about getting them and have been inundated with requests for installed pics. This is why I stayed up late last night to install, take pictures and start this thread.
Note the ducts offered as an option on the 2016 C7Z are NOTHING like the ones that I received with my 2017. The ones that came with my car are much more complex/effective than the ones you refer to. In my prior thread someone posted a picture of the ones you reference. Big difference and those did not come with wheel blockers.
A link to the original thread I wrote is below. Scroll down to Post #4 and you'll see the ones you reference as being available for 2016. Apples and oranges....

Yes, since I referenced the 2016 Z06 and didn't check the Stingray and Grand Sports sections.
