Custom Vented Fenders possibly in production; suggestions?

How do those vents provide cooling (i.e. providing fresh air) to the bbk?? One would think the vents would need to be located infront of the wheel wells for that to occur

lawl fender vent in front of the wheel hahaha
i think (at least i hope to think) he meant brake duct
the fender vent will allow better airflow between brake duct and fender hence better cooling
not even physics, just simply common sense
like a computer...u got intake fan and exhaust fan to maximize airflow

exactly my thoughts, our cars look too clean & simple for vented fenders, thats why im wondering, with a full wald kit, lowered, red popin bbk, can i pull off these vented fenders without it looking out of place... i duno....
do i want my car to be different then all the other isx50's on the road, yes.... so hmm... guess we'll see what happens
either vented fenders or vented hood ( but a custom one )

You and I are going to look like twins, currently building custom vents for my hood, as well as the fender vents. Did I mention I have a wald front lip and skirts on the way, and i'm molding my spoiler currently. Anyways, I think it will good man, aggressive and different but still good!

that fender looks hella sick
do you have any front shots of his car, wondering how agressive his front end is?
im worried my car doesnt look agresseive enough to pull off the vented fenders
not really feelin the first car thats primered, doesnt flow at all

The function of the vent at its location behind the wheel is to dissipate heat/hot gasses, not provide cooling. Those are two entirely different concepts. To "cool" your brakes, you will need to run ducting from a source that preferably provides non-turbulent air (i.e. front airdam). Air circulation within wheel wells happens to be turbulent and swirls violently in commercial application such as our IS.
Come at me bro, I've got multiple engineering degrees!

I corrected your statement.

It's all semantics. If you pull out hot air, is it not replaced with cooler air? "Sucking" isn't the right way to describe it, but the concept is clear. Fender vents provide a "passive" cooling function, where air dam ducting provides an "active" cooling function, from what I understand from your post.
Science aside, just like how some on this forum translate increased growl from adding an intake to increased power and better acceleration, fender vents have the same placeobo effect with "cooling". Our car's brakes do not produce enough excessive hot brake gases to produce brake fade during everyday driving, or even the occasional track day. Fender vents therefore are purely for aesthetics b/c they are not needed.

I think rather than arguing about the science behind the vents, the real discussion should be:
Will the vents actually provide any increase in braking performance on this IS application?
And if so - will this IS actually be tracked and the vents put to proper use?
I'm all for making a car "your own" - but when goofy (imo) aesthetics are added, it's kind kind of corny.
Goes right along side of the fake/non-functional hood scoops.
Just my friendly opinion.

No, it's not semantics. It's fluid dynamics and aerodynamics. If you understood Bernoulli's principle, you may agree with me. But hey, believe what you want.
Science aside, just like how some on this forum translate increased growl from adding an intake to increased power and better acceleration, fender vents have the same placebo effect with "cooling".
