Default Bumper air inlet / brake ducts?

I ordered some of those nifty looking little air inlets for aesthetic purposes only to realize that i have to cut holes in my bumper for the ducts to protrude into the bumper. So i will either return them and keep my lights or go further by doing the full brake duct kit (hoses, deflector, etc).

Can someone provide some feedback on the benefits? Are they noticeable? This car is maybe 2-4 track days per year if I start using it as such. So far it's just a drive around car.

Car has big brake kit.

I have some for a track car and found while they look cool - they do little to cool the brakes unless they are properly ducted.

More benefit came from removing the back metal brake shields.

Second to remove brake shield. I removed mine made small shield for sensor and ran hose to brake disk center using a custom made mount bracket that bolts on the caliper mount. Works great lot of air flow from inlet in front airdam. NOT the light replacement duct.

Look who came out of retirement? Or did you retire and now you're here?

I decided to vent mine to the dual oil coolers. My brakes barely come to operating temp with endurance pads lol. At current pace / r-comp tires.

I don’t want to derail this thread but yeah - someone left the backdoor unlocked so I snuck back in. 😁

Good to see you back Marc, hope all is well with you, your contributions have been missed (and missed you at the track these past few years)

Oh, and I agree, if you are doing brake ducts, then you need to run the hose to the hubs, only way this works effectively. otherwise, as been said removal of the backer plates provides a considerable increase in air flow.

Some people will say that it will diminish your 'wet weather' braking as the rotors are now more exposed to splashes from standing water etc, I have not noticed any real negative's of removing the backer plates.

The soft pieces like wheel speed sensor and ball joint rubber need to be shielded from heat, hence the cut down versions used on Cup cars

Just a late follow up to show the mods that I made to keep front brakes cooler as mine get hot. I did take a different line ( thanks 911 for this) and ran my hose in the frame channel then back out to get around tire due to limited room. Also you can see small shield that I made along with hose mounting bracket. you can also see the front brake scoop that is built into my front area.
