Help me settle an argument.

It will help the car's performance on the track. I don't think Ford would have changed the spoiler used on the base/tech models if it didn't help. As this may be well and good when using the car on the track, the vast majority of the time, the car is driven on the streets. That being said, I personally do no like the aesthetics of the track spoiler. I think it breaks up the beautiful silhouette of the Mustang's lines. The "lip" spoiler is just enough to aid airflow over the rear of the car and complete the lines of the car. This is not a put down on track cars; rather, when I (just me) look at the side profiles of both cars, the base/tech equipped "lip" spoiler cars just look better and cleaner.

uh, YEAH! Mine made so much down force that I had to adjust the trunk lid stops because it was making contact with the tail lights. I just tracked mine at Barber on Saturday and can guarantee that the spoiler makes a huge difference at high speed. Additionally for Redline77, I traded in my '15GT/PP that i also tracked and there is a huge difference, HUGE!

 

[Zitrosounds]

You'll never notice the difference. Probably won't even matter for lap times for 99% of the drivers.

Guess I am in the 1% but I am sure that the percentage is actually higher factoring how many on Mustang6G are tracking and going to track there cars.

If that truly is the case, that is not good. Downforce should be pushing the whole car down into the ground, not a body panel into the super structure.

Super structure? The whole car down into the ground? Your reasoning is flawed. 1. the spoiler is not over the whole car and only creates down-force at the rear. the front split-er creates down-force fwd, belly pan and rear diffuser create a vacuum which pulls the car to the ground, granted none of these effects are realized at low speeds. 2. the only support structure under the spoiler is the adjustable stops which make contact with the trunk opening. the trunk lid stops have been properly adjusted and no more issues.

You're thinking entirely way way too hard. I was simply pointing out that if there are body panels that are getting squashed together, the downforce is going to waste unless you make adjustments like you did. Calm. Down.

Spoke to my Ford contact. It does make a difference on the longer tracks where high speeds are in play. As we suspected.

On the race car, I run a Gsteam. At smaller tracks, she stays pretty much level. Large tracks is a different thing

You must be a pretty good driver. Even for the people who track their GT350s, unless you can push the car to use the additional aero grip, it won't make a difference in lap times. I've tested this theory with my POC buddies on a 997.2 GT3 and a GT3 RS few years ago. Surprisingly, some people went faster on the normal GT3 due to less drag.

It is not necessarily about the lap times but the stability provided at high speed. I consider my self a better than average driver and always run in intermediate groups. Have only been passed in the GT350 by C6-C7 Z06's with slicks. Would have passed the GT3 RS but never got the point by, I started at the pack of the pack. The GT3 RS was 2nd row. Had to leave the intermediate group because no one was pointing by, pride i guess.

Best time @ Barber with traffic in the novice group 1:50.46.

If you push down on the deck lid with your hands/body, you will deflect the trunk stops just like he said. This weight is still transmitted to the tire and ground to make grip, the force does not magically disappear due to deflection of the mounts. In terms of deflection and force, there's no difference between the air pressing down X-lbs vs your hand.

-Yes the track pack makes more rear downforce, grip, and stability over the base "spoiler". If you're driving at low speeds and far from the limit, you will likely not notice a difference while someone who is near the limit will have a noticeable increase in stability and grip, especially in 80mph+ corners.

That's pretty good. Can you really feed the added stability? I've driven both tech and track up to 150 mph, they feel the same to me.

I can not compare vs the Tech since I have not driven one. I can however compare to my 15 GT/PP (PP has a spoiler delete which is essentially what the base 350 has) that I also tracked and the stability difference at high speed is significant. how much of that is due to the actual spoiler and not the suspension? I do not know. My buddy has a C7 Z06 and I used his time to bench mark my self. His Z06 @ Barber (separate event) with track wheels, slicks and track alignment ran a 1:45 vs my 1:50 on 28psi tire pressure. The Track Pack GT350 is very capable, I can only imagine what a set of track wheels and tires with a track alignment could manage.

Basic logic would say that more downforce is better which the track pack spoiler would provide vs not having one. But I think you'd only notice a difference at high speeds on a track.

 

[M3Convert]

The base "spoiler?" Yeah, I'd say probably useless. You'd probably get more downforce by sneezing upwards out of a sunroof.

LOLZ!

I am glad that you didn't go on on to point out that going on a diet and a good crap before session #1 is a more cost effective way to reduce curb weight than a carbon fiber hood and trunk panel. That would be heresy!

I would agree with this. While the track packs spoiler is larger than the tech pack I can't imagine you would notice too much of a difference between the two. It's just not big enough. Now, the R spoiler on the other hand looks like it produces some decent down force.
