    Automobile Magazine reported...

    "Ford’s long-anticipated, upcoming Mustang Shelby GT500 produces maximum rear downforce of 550 pounds at 180 mph when equipped with the optional Mustang GT4–like rear wing that comes as part of the Carbon-Fiber Track Package. The downforce number is 379 pounds at the same speed from the Handling package’s smaller wing that features a Gurney flap (for context, the Ford Shelby Mustang GT350 produces a tad under 300 pounds of maximum downforce, the company says).

    Ok, well that is a big statement from anyone. I still don't know who he is. And if so, what's with all the questions?

    I’m talking about the difference in weight not downforce.

    I’m likely not gonna be able to swing this car, but these performance rumors have taken my excitement to see some of you get these to a new level. Sounds to me like it’s gonna hurt some major feelings.

    Heres a Snipet of myself from our Daytona 14 Hour Race in one of our Boss 302R's. This is also on a 200Tw Street tires, We ran the same set for 14 hours straight

    If I remember correctly he's a fairly young kid that built a car along with his father and has SCCA, NASA, and possibly some AER experience. He's done chump races too. He's done well.

    On edit....see previous post, lol.

    So based on your earlier statement, either you've spent a bunch of time A/B testing different designs of carbon fiber rims on track vs. aluminum or you know someone who has?

    Please tell us where your in-depth knowledge of carbon fiber rims has come from.

    No, But i have cracked enough rims to know that if you are going to ACTUALLY track the car more then 2-3 times a year that putting aluminum wheels on is the much better choice. Also Aluminum is less likely to shatter like carbon would.

    Im not Denying that the CFTP vs Base will be faster in stock form, But they are all easy to take care of differences.

    So you are saying that your extensive basis of knowledge comes from an engineering or manufacturing engineering background where you have built and destructively tested many different designs of CF rims vs. similar aluminum rims?

    I wouldn't call that 10/10ths, however nice driving. I noticed your line varied a bit around Rolex turn 1 and 3 with no reason for each variation. I like to stay low in the banks..... you can pick up a little time there too. I couldn't sit and watch the whole thing but 2:06 are decent lap times. I'm right in that time bracket and I do not call myself a 10/10ths driver. I noticed you spend a lot of time with your right hand on the shifter and not on the wheel. I'm sure you know this, but my biggest concern at Daytona is when a tire delamination occurs. The guys who I have seen save the car from the wall are the ones with both hands planted on the wheel.

    Anyway, I didn't know who you were (or are), but you and your driving certainly qualifies you to make the observations you did.

    Nice job!

    So basically, give or take a bit, stock, we might be looking at around 5 seconds between the two.
    Sure, you can do add ons and deletes to make the base car faster. Mod to oblivion if you like!

    I should have stated I was not going 10/10ths in the video, Right around 8.5/10ths. This was hour I think 7 or 8 of the 14 hour enduro, so no reason to destroy the car. I went on to drop the time down to 2:04, on 275 Street tires (Hankook RS4)- https://speedhive.mylaps.com/Sessions/4905214 Like you I also found that staying low on the bank would improve lap time but with lapped traffic and a pretty high speed differential I stayed up high and out of the way. You are defiantly right about both hands on the wheel, Bad habit I have But with our Aero the car is pretty planted at speed.

    As far as tire delam I actually cracked one of my wheels in about Hour 12, The nice thing with the street tires they are way stiffer than slicks so they can take a decent amount more abuse. We ran the entire 14 hours on the same 4 Tires ( other than the one that was changed.

    I look forward to going to the Daytona December Audi/Mustang event, Hopefully I will have a GT500 by then and will Defiantly be bringing it if I do.

    If my car gets built in time, then we should be the only two there with 500's. What group are you running in? I assume 1? I drove group 2 last year. I was lucky to have a very good student.

    Not sure or signed up yet. I'll be in the most advance group since I have my Comp License.
    Trying to decide between that event and the 25 Hours of Thunderhill. Still a way aways.
