Guys who run without Fender liners at the track
So because my car is a bit low.. and fender liners kind of get eaten up with suspension travel . I have not been running them ,
The other day I saw a diagram about the fender liners and air flow . with the oil cooler ..
and since seeing that I had a thought could the heat from the oil coolers feeding directly onto the front tires cause some of the heating issues with the FD brakes?
Or when you are at the track basically the air flow at higher speeds kind of makes it irrelevant .

Zip tie the harness up high above where the metal hangs down and you won't chew it up, the tire will have to rub through the chassis 1st. You'll know what I'm talking about when you check it out.
For the track there is only one solution for keeping the brakes remotely cool and that's ducting which is a PIA.
Liners are not very important other than keeping debris and water out of the engine bay
If you go with out liners I'd install screens attached to the back sides of the oil coolers and to the engine bay openings.

AFAIK, that diagram you attached is only for the 99+ rx7s. they had a functional fender vent and fender liners that attached to it. the 93-95 do not have a functional fender vent connected to the fender liners.
can anyone confirm this?
When I took the fender off of my '93 I could see a black plastic duct which routed from behind the oil cooler to the fender vent. It attaches to the top of the fender liner.
Found a pic...

Visually they appear to work. The more important question is with all of the modifications we do to our cars do they still work? Those systems are designed to work together and many people are missing plastic components so they dont work as well.
oh that's cool! next question: do they actually work???
When I race in the rain I do get evidence of dirty water exiting the fender vents.
I always viewed the fender vents as-
Mazda really wanted the fender vents for stylistic purposes, but couldn't bring themselves to put non-functional vents on, so they found a way to kinda make them do something.
-----------------
Venting the oil coolers straight into the fender wells will work much better, though slightly increase front end lift (but also brake cooling).
Then, using the now "non-functional" fender vents to vent the wheel well high pressure probably would have provided a net improvement all the way around but left the outside of the car filthy every time it was driven.
The 2nd gen had better aerodynamics and less lift than the FD with its gaping brake cooling ducts feeding air directly to the wheel well.
Venting the oil coolers into the sides of the engine bay probably would have been a good thing increasing airflow through the cramped hot engine bay.

I get that to , dirty water out of the vents . and I dont have any kind of fender liner LOL well atleast it means its letting some of the trapped air out .
