raising the rear roll stiffness with springs does not reduce grip. it raises it.

it is the change in weight transfer f/r due to the stiffness that changes the balance of the car.

I would argue, that the toe out method of getting oversteer would be less effective than moving weight around, or tire sizes, or roll stiffness.

but I could be wrong =)

suspension isn't simple, and the fact is not even top F1 engineers can tell you what the best solution is, you just have to play around with it.

for instance, top E36 BMW drivers Brian Matteucci and Bob Tunnel use vastly different spring rates in the rear. But both are insanely fast. There are often very different but equally fast suspension setups.

Because it flat out works better for SoloII. Increasing rear roll stiffness is well and good for making the back end slide around since it also unloads the inside rear wheel more, reducing available traction even more. Adding toe out in the back results in the outside rear wheel helping to "steer" the car around while the inside wheel is planted a little better. More power makes for more steering effect, which points the car faster so you can unwind faster and get forward bite quicker without waiting for grip to return.
