BIG F1 fan here. The F1 cars acutally have an inboard coilover shock system using rocker arms and push rod. This was the insipriation behind the REVO. They rather have the shocks inboard so they could reduce the amount of airdrag. Mostly for F1 it all comes down too 4 things: Tires, Aerodynamics, RPMS, and driver. As for dragsters, i have no fricken clue

Yes, but make sure you keep the magnetic strips aligned or you'll encounter torque steer.

So we can assume that nobody here actually "knows" the answer to this.
I think that if you could optimize the suspension then there would be no need for pneumatic tyres and the chassis could be very rigid, in the real world everything is a compromise and we make allowance for our lack of perfection.
Now I'm off to break my goat's spine and see if he handles any better.

Well, we've yet to see any convincing reasoning in support of the flexible chassis notion.

. . . . though hitting a gutter at full noise could be one of them.

If you want to see a full blown debate about the chassis flex VS handling issues, check out the HPI pro3 thread in the electric forum. As you might know, the Pro3 was designed with a flexible tub chassis to optimize handling on bumpy parking lots. I think that the general concensus is that the better the driver, the stiffer the chassis needs to be, while the flexable chassis make the car easier and more forgiving to drive.

Here's a bit of F1 chassis flex.

Taylor, yeah, that's probably more flex than I'd ever want ... in any car.
