Nice way of saying what I've observed. I guess that I'm lucky to run on very consistent track surfaces. Sealed parking lot, ozite carpet, and a concrete super-speedway road course.

It took about 3 race weekends to dial in the car for each surface. Once I hit it, my car was very fast and very predictable. Just loose enough to rotate fast but just tight enough to turn in well and accelerate well out of the turn.

So stiff is good, if you know how to set up your car. Also explains why real cars run softer setting in the rain then in the dry.

Just a tip from full size racing.

A stiffer chassis will work better if it is set-up properly given a consistent racing surface. The set-up "window" where the car works is smaller because suspension changes have more affect on the car.

A more flexible chassis will often work better when the track is slick or inconsistent because spring and shock changes have less affect. The set-up window is larger but the chassis won't ever be "perfect". Sometimes this can make the lap times faster.
