vented BRZ fender trim?!

Yea, roughly this much:



I didn’t cut under the slot cause there’s a chassis beam behind it anyway, not much air coming from that.

Do you think the extra cutting makes a difference? Or would the air still stream through without it being cut? Maybe the smaller exit would create a vacuum?

Yes the cutting makes all the difference. A smaller exit will not create a vacuum, just less flow.

I will likely do what you did, but keep the clip parts and cut in between.

So I got the fender garnishes. I am cutting out the spots between the clips from behind, but not the black trim part. Just the backing behind it. After that I am drilling multiple holes along the angle lines of the black trim part. Not sure it will be enough open space , but I want to go subtle first before I go big and cut it all out.

Pictures of your progress would be appreciated!

Would drilling a bunch of holes so it's essentially a perforated fender area allow the heat to be reduced and retain the factory clip locations without ruining the cooling abilities of the rest of the cooling system?

I think you'd need multiple temperature probes in a few different locations around the engine bay and a few test drives or a huge dyno styled fan to test all of this....

also would require airflow sensors to determine if it's helping or hurting aerodynamics as well.

Here is what did. Still have stock ones in case, but went for a drive. When I parked the car in the garage the heat is pouring out of the fender garnish. Have no idea if it works at speed. It’s good for now, not perfect but I like it. All clips were used and new 3m tape. Let me know what you think.

I trimmed down cast aluminum registers to make my garnish vents. This allowed a large openings in the fenders to let air out of the engine compartment.

Nice job, but I would get more of a grill with smaller holes. I think it will look better and still allow plenty of air flow.

I'm sure there is a better option out there but these were less than $20 each.

damn thats function over form for sure!
