McMoney's car didn't have the new one piece diff housings and the new 4 point layshaft mounts. Both of these changes make the car stiffer. The way the front and rear shock towers bolt to the latest version of the car also give it a stiffer more box like structure.
Keep in mind that stiffer is not always better. The stiffest car available now is the Graphite XXX-S. However the really fast team guys all mill holes and slots all over it to get it to flex more.
On some tracks Factory AE drivers run a graphite chassis with almost all the ribs milled out so the car flexes more and generates more grip
Factory Xray drivers all run the Raycer molded chassis (a stiff version you can't buy right now) that flexes more the and Evo 2 Carbon chassis because the car is faster everywhere like that. The also have 4 diffrent top decks. A stock stiff deck and 3 pregressively more flexy decks. Most of the factory drivers run the 2 softer decks.

How does a car that flexes more produce more grip? I think this is just a way to compensate for an inaccurate setup, where their suspension isn't doing what it is supposed to.
This would make the car more forgiving, and perhaps easier to drive, but far less accurate. If you had a 100% perfectly tuned suspension, you would want 0 flex out of your chassis.

Your exactly right about using flex to compensate. A tuned amount of flex is designed into every R/C car on earth to make it handle better.

This discussion i nothing new. I have posed responses on this matter a dozen times in the last 10 years that sedans have existed. It goes further back than that. Stiff pan cars didn't work right either. 50% of the suspension on a pan car is controlled chassis flex and they are WAY faster than sedans.
History Lesson
Yokomo releases a budget plastic molded sedan the Mr-4 and finds out its a better car than the big $$ carbon YR-4 Pro.
The car sells well and racers ask Yokomo for a higher spec graphite molded kit. It comes out and it handles like crap....Until Masami Hirosaka and Barry Baker figure out that if they mill out a big chunk of the top plate the car flexes more and handles better. The first gen MR-4 Pro was terrible until the kits started coming with the milled top decks. Yokomo won everything for a year and a half with that car.
Over the years there have been super stiff parts made for just about every car. They all accomplish one goal thay take a good car and make it awful.

And all this tells us is one thing......racers know what they WANT.....but not necessarily what they NEED!

If your talking rubber tire carpet or rubber tire asphalt then yes stiffer is not better but here in the states almost all of the big races (indoor) are foam tire on carpet... there stiffer is better. I twisted McMahons car at Cleveland and I thought it had lot of flex... I am glad to hear the final version is stiffer. I am not bashing the car either... as I am on the list for one.
