GT500 Track Performance

[Wildcardfox]

Well the CF wheels are sadly not very useful on track once you start going 10/10ths. In Pro racing their is a reason you don't see Carbon wheels.
Also MUCH higher likely hood of damage on track. Same with the tires, Cup2's last about 4-5 track days and they are done, With the extreme weight of the vehicle comparatively may even be less.

The Wing is Nice But I can get one for around 12k I think, and I can get better performing options for the wing for around 2k.

This is an excerpt of an interview that I can't use in an article. It is what Johnson thinks of the carbon fiber rims in on track performance.

"What's the difference between the GT350 and GT350R? 5-seconds at VIR. Tires, wheels, and aero. The tires are worth about 2-seconds. The aero is worth 2-seconds—way in the back, less top speed, air damn in the front. The wheels are worth a second. Rotating mass, less unsprung weight and it’s also less flex. Aluminum wheel with actually bend a little more, a carbon wheel is very strong, so you don’t get the flex and you have the rotational mass is worth a full second at VIR."


Regulations in racing sanctioning bodies has a lot to do why you don't see them in racing.

Rear seat saves around 40 Lbs it looks like, Not sure on wheels

To be clear - that is the weight of the rear seat and associated ancillaries. When you add the weight of the RSD kit back in you are then saving a total of about 32lbs.

Finally, a great thread thats due.

I just want to know the other #'s
1/4 miles for each and weight

Start the ricer math vs its competitors etc etc

10/10ths is a big statement. Are you a 10/10ths driver? Tell me more about your driving......

He can drive Tom.

Apparently, there is about a 150 lbs difference between the CFTP and "base" GT500. I'm not sure if I buy that as around 100 lbs is more likely much like the GT350 and GT350R.

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.

AER, SCCA,WRL and Champ Car. Next race is Champ Car 24 hour at VIR

Good luck!

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.
