The RSR was done to allow for a proper rear diffuser on the car. It was an aero change, not done in the name of balance necessarily.

With the BOP it's impossible to compare advantages with the other cars. But they obviously did it for a reason.

I don't think the chassis has ever really been sub par, I know they mitigated the issues with the recent cars but I still see a ton of 996s at the track.
True, I didnt consider that, BOP still brings a tear to my eye. I just dont understand the point of racing anymore. Even in my local beer budget league I got BOP'd out and now have to run a 340tw conti extreme contact... **** that, just going to build my shitbox to the max with more power and aero and not compete lol

Frank Walliser, who heads the Motorsport division, said it was for weight distribution. Apparently Porsche had been kicking around the idea for a long time.

It also happened to help with aero.

"When I took over Motorsport in 2014, there had already been some studies for, let me say, optimized weight distribution," said Walliser. "In March 2015, we made the final decision with the board and everything–the concept was there, and we did the studies, then we started with the engineering."

Everything I saw at the time said it was for aero. I would imagine Porsche would put itself in a tough spot selling rear engined cars to customers then racing mid engined because they are 'better balanced', so maybe the real story isn't discussed to keep the customers happy?

Our First Look Inside The Porsche 911 RSR Shows How The 911 Went Mid-Engine
The reason for this change, as we know, was to accommodate a gigantic rear diffuser that was recently allowed for GTE-spec race cars. That diffuser sits where the bottom of the 911's rear engine usually sits.

Here is the Road and Track article. Sounds like both the diffuser and the weight distribution counted toward its performance increase.

To be fair, they did move the engine in the RSR from rear to mid. There has to be some advantage to it.

Alters the car’s inertia, which significantly improves rotation, squat and dive, which gives more latitude in spring and damping rates. Yes, that makes the car accelerate, brake and corner better.

I'll be curious if this has any off throttle snap oversteer like the 911 used to. I'd really like to drive one on track to see how well it handles weight transfer from modulating the throttle.

My C6Z has snap oversteer, especially with low fuel. Pro drivers can easily catch it, or induce it, then throttle steer the car (see Tiff Needell vid on YouTube). Everyday club racers / HPDE blokes like me have to work a little harder to do that.

I agree that the proof will be at the track in the hands of the intended track enthusiast customer - especially in the wet.

But as someone said, what a great time to be a car guy. Screw brand loyalty. Buy what makes you grin. Buy the car that you can’t help but looking back at after you park it and walk away.

Those are rear engine platforms...
What??

No sir. They are mid engined sports cars.
The 911 is a rear engined platform, big difference.
If the weight of the motor sits in front of the rear axle, its mid engined. if it hangs over the rear axle, its rear.

Plenty of crazy statements in this thread, but you may have taken the cake :)

that 850hp at 5000 rpm is awfully low. Is that common with FPC turbo motors? I figured they would need all that rpm to make the power. Why even go FPC, CPC way less NVH to deal with?

So setting a engine in the back of the car is not rear engine? Ok

Damn I thought the c8 was impressive but it’s just another car.

I remember when they released the RSR, they made no mention of it. It was basically people looking around the car that started to notice the engine had been moved forwards. There was a ton of speculation/rumor until some people finally came out and asked.

It's a touchy subject for Porsche I would say, the 911 is their darling, and having a rear engine is a big deal for that car. I can see why they didn't come right out and say it though.

Engine in the back is a loose term. Diablo mike is correct. Mid engine is not rear engine

I seriously can’t tell when you’re trolling or being serious. You post some crazy shit sometimes.
I’ve always looked at cars such as boxster cayman different than the Ford GT’s 360 430 458 488 Lamborghini McLaren and such.

What do we call the Audi with motor mounted behind the front axle?

The C7 has the motor behind the front axle as well, still front engined but 50/50 in C7Z trim....

Because its in front of the driver?
I dont think anyone here decided what defines a mid or front engined car, most of us are working with what has long been considered 'common knowledge' as far as I am concerned.
Not here to defend anything, and if you feel better calling a C7 Mid engined, go for it, just expect silly looks from people if you bring it up in conversation :)
