As it regards power steering, I'm actually considering that for my ERA. The G forces are so high in very tight cornering at speed that is extremely difficult to maintain effective control of the steering wheel. This is especially true when your running road race slicks. I've had the car sideways and sliding and it takes immense effort to counter steer in that condition, at speed and with slicks. It is particularly problematic when your coming out of a corner and need to quickly take a new line.

I've found I prefer zero or even slight toe out for auto cross, where the speeds are generally below 80 mph. But the car is a beast to drive that way on the street and becomes unstable and "twitchy" at 80 and above. Downright scary in fact.
