Easy fix! Just go back to bias ply tires! NASCAR was fun when with all cars where on new bias ply tires as they came around those first turn! Lots of sliding and rubber in your face if you were near the rail! Had 30 tickets to Darlington and would bring customers. Had to move up and get seats away from the rail!
I'm sure they will get the suspension so it doesn't "push." As Andy Pilgrim said it takes work on the suspension!
The current 911 has its 6 cylinder engine in the same place as it was in its Beetle ancestor.
Not Quite. As model changes have occured in the 911, Porsche has been moving the engine forward until in the 911 RSR the "Water-cooled six cylinder boxer engine is positioned in front of the rear axle".

The new RSR, however, is an honest-to-goodness mid-engine 911. . ,
"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." . .. .
"It's not a waiver," said Walliser. "It's written in the rules of GTE that you can do that. As long as you stay on your platform, no problem."
"So as long as it's a 911. . ."
"No discussion," replied Walliser.
This seems crazy until you realize that most front-engine GT racers do virtually the same thing. Both of the RSR's front-engine competitors, the Aston Martin Vantage GTE and Chevrolet Corvette C7.R, have engines pushed further back in the chassis for better weight distribution.
"At the end of the day, they want to see their brand winning," said Walliser. "Number one is winning; number two is Porsche; number three is 911, and then it's maybe 'where is the engine located?' But if you win, nobody will care."
By the way, there are rule limitations to how far you can move the engine, but the "street" 911 engine had moved forward enough that the final move to mid rear could be done within the rule limitations.
So to paraphrase Wallise,is it ture that "Number one is winning; number two is Corvette; number three is Stingray, and then it's maybe 'where is the engine located?' But if you win, nobody will care."?

My 1990's 911 GT1 was also a winning Porsche ME! Mine is a bit small and have a pic of a cut-away as well!

kind of defeats the purpose... now i still have a heavier rim and tire, and also wider than needed (wide has negative tradeoffs on uneven pavement)
Bigger is not always better... but we will see how it goes.
I think DSC Sport Mike is going to have his work cut out for him on this new car, i believe they are going to be having to release all custom control arms before he is happy with the car.

At times designers win! Fat tires are an esthetic issue as well as functional in certain situations.
I agree they no doubt have looked at many ME rear suspension designs and have included extra suspension components for optimum handling. The C8R may go further.
All they did for my 1967 Corvair was use 3/8 inch rear toe-in to help manage oversteer! In a high "g" turn that outside rear tire was steering the rear back in from where it wanted to go! Helped to a point! Loved that modified '67 that I went Plus 1 with 14 inch wide Low Profile tires. Plus 1 and Low Profile were not words used "in-the-day!" Took lots of measuring but those Continetal 714's stuck like glue and were good in the rain! When I sold the Corvair and bought a 260Z, bought "Minilight Look" wheels and installed those 714 tires that still had half the life left!
"This new engine (L8T) sports the larger 4.065-inch bore (as used in al the 6.2L engines) while adding displacement through a simple stroke increase from the current Gen V 3.62-inch reach by 0.240-inch to 3.86-inches. This calculates out to 400.7 ci (rounded up to 401) all wrapped up in a cast iron block with aluminum heads."
As this is achieved by a GM stroker crank which is forged and should be a straight swap into an Al block, LT, a 401 could easily be produced for the C8.
Should be an easy 500 hp with nothing else fancy to be done.
Great surprise given he worked for a company that built front engine cars & did not want to spend the money Duntov wanted for a mid engine Corvette. That said he did drive a number of GM mid engine cars to various records.

Corvette CERV III
Mid engine Corvette that might have been.

1992 Jaguar XJ220 that actually WAS....
looks a lot like the CERV III to me.
