CT4-V Brake ducts install

[Sebring20]

Hello, has anyone done the install for the brake ducts that come with the car?

Can't find a good video on how to do it on the CT4. Saw one for Camaros, is it pretty similar?

Do you have a problem if you leave them on while driving on the street?

They should be very similar to the Camaro. The recommendation is not to run them on the street because along with tons of air they also direct road debris onto the rotors and part of the install is removing the rotor guard leaving it defenseless.

They are a bit of a pain as you have to remove the rotors, both front and rear, to be able to pull the heat shields off, but it's not the worst thing ever. I run with them on all the time and I drive the car daily. I typically run a track event once a month during the summer, so it's not worth the time and effort to swap them on and off multiple times a year. I've had no problems so far leaving them on for street use, but if you're worried about it, just put it back to stock.

Did it make a difference on track?

Don't really feel like taking the rotor off and the whole nine yards. Might leave it until I need a rotor/pad replacement in that case

It will help increase the life of the pads and rotors. I actually did my very first event with the car totally stock (no track alignment, no brake ducts), and while the car still performed quite well, it was starting to chew through the tires and brakes faster than I would have liked/expected. I expected as much from the tires since the stock camber is way too low for track usage. As for the brakes, while the total braking performance did not seem to be too different between the two setups, it definitely helped keep them from getting too hot and getting chewed up quickly. The stock pads will get eaten up quickly if they get too hot.

Do you mean the rotor shields? Not the brake ducts that clip on to the rear suspension?

I've had the big shields off on the front since new, with the little tomahawk shaped track shield installed instead, and both shields off on the back for the last year. I did not put the plastic ducts onto the rear suspension. No negative effects in my experience from getting rid of the shields, obviously just one data point. Camaro ss 1le and ZL1 1LE ship from the factory with a front rotor shield very similar to our tomahawk track shield. I think the ZL1 shield might be exactly the same.

While it's not like the brakes are going to fail your first time out with the shields on, the front brakes take quite a beating and could certainly use the cooling help if you were starting to push on track especially on a heavy brake wear track. I don't know how needed it is in back, the pads in back last way longer on track then the fronts.

It's apparently possible to remove the rear shields without pulling the rotors. Mirza the CT4 engineer had a post about that and the whole issue of brake cooling on a different forum, I think it was the forum for V Club. Apparently if you pull the pads and remove the rotor screw, you could wiggle the rotor to get enough clearance to remove the bolts holding on the rotor shields. Which is good because the rear rotors are a bit of a pain to remove. Fronts are straightforward.

Makes sense, I ran with track alignment and have great tire wear. Nothing on the edges at all. Brakes I did notice crazy dusting but still looks like good pad life (only 6k miles, 2 track days)

Thanks great insight. I guess I just need to get under the car and see

Ohhh I just realized for our CT4s, its only the rear ducts and smaller front dust shield. No front ducting like the 5s. The bag I have says DEFLECTOR KIT-FRT making me think its a front kit. I should have read the manual in there LOL

Ok I think I wont bother installing then..
