What are GTS-ACR Fog Light Covers?

Just read this in a ad and have no idea what GTS-ACR Fog Light Covers are. My '98 RT/10 came with factory fog light covers and those are the only ones I've ever seen on anyone's Gen II.

Thanks

Trick Question....

GTS-ACRs did not have fog lites, much less fog lite covers.
What they DID have was black blocking/backing plates to fill the empty holes.

Here is a pic of mine. Used to block the hole where the foglight is normally.

Can be removed for brake cooling ducts:

here's a set that looks much nicer than the factory covers

Reminder...TOTAL waste of time to try and pick up ducted air from these openings. At speed, they have a negative pressure, and **** air around and past the duct. There is POWER to these holes, so you could install BRAKE COOLING FANS...., but static ducts would be a waste....

Interesting. I was always under the impression that the race GTS-Rs got the cooling from those ducts!

Guess I was wrong!

I have heard that b4 but, due to the amount of bugs that i always find on the foglights, I'm not so sure about it.
If I had air ducts going to the rotors instead of the foglights I imagine that the bugs would end up on the rotors.
maybe I don't quite understand your comment about "at speed".
Do you mean that the pressure change from positive to negative above a certain speed?

Tom;
Thanks for the very interesting link.

The airflow was exactly what i was expecting, the front of the viper is slightly V shaped and obviously,fluid taking the path of least resistance ,the air on both side of the grill opening has no choice than go left and right.
BUT, the viper on the pictorial seems to have the fog light or a cover on so the airflow is backing-up in front of the fog light and slide to the side..
I think that the "problem" is not location but rather design.
If I wanted to use the fog lights as air duct, i woud put a 1/2 moon shaped shield,extending forward about 6" on the outside of each fog opening.
All the air that is now deflected to the side would be forced inside the air duct.
On one of my race cars (a 69 Mustang) the outside headlights are located on both side of the grille opening with the front of the car having a very prononced V shape and when I decided to use those headlamps opening for air ducts, without those shields I was getting very little airflow and brake fade because it was easier for the air to slide by the openings.
The shields made a huge difference.

Luc,
While the body shape is different, the pictorials (image 4) of the air flow direction would be similar. Notice the "arrows" are parallel to the body in the vicinity of the fog lamps rather than perpendicular. That would indicate a low pressure area.

EXACTLY !!!

The bugs that hit the foglites at 5-25 mph die there. And the wings even stay on em! There is not enuf wind pressure to tear the wings off.......

Those bugs enroute to the foglite at 30mph plus are sucked aside.

You dont need brake cooling at < 30 mph....... The lower GTS-R had a different fascia, as well as splitter-airdam and canards. Totally different front...and SOME of them had blower brake cooling fans as I mentioned earlier in this thread. Those PULL air thru fog ducts.

Insect-Aero fact # 3: If you look at the back end of a GTS Cam-tail spoiler, the suction at the rear of the car at certain speeds below 75 mph can actually SQUASH GNATS on the tail panel rear stripes, adjacent the CHMSL and above the license plate. When you wash your car you will sometimes see tiny bugs ......DEAD... on the stripes. This is more pronounced on yellow cars,,,,,and NOT because as Chad sez they **** more......

The GTS-R brake cooling evolved constantly over their production life. Here's the 1997 GT-1 version:

The area UNDER the front splitter is a high-pressure area. Allowing this air to escape upwards to the brakes achieves a dual goal: Minimize lift, and achieve brake cooling.

I installed 2 down-facing, screened NACA ducts under my facia back in 1993-1996... Held in with the fascia mounting screws. Routed the hoses as ORECA did, with zip ties to A-arms. Total cost $76...... It works quite well! Timberine Dodge made and sold these kits for years, my FIRST Viper mod for sale!
