Cobra Geometry Challenges!

[Excaliber]

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.

Thanks for all the great help guys! I'll definitely be getting the measuring device - if only to be able to check and reassure myself periodically that things are the way they should be. Thanks for the link Cobranip. Yes, I have four corner adjustable coilovers. As for the manufacturer's recommendations....mine is a West Coast Cobra - the recommendations consist in a few assembly instruction sheets, a "good luck" and unanswered phone calls

About the spring platform adjustment - I remember cranking the spring platforms on my motorcycle years ago to adjust spring preload for different riding conditions. If I use this method to adjust ride height, it seems it would preload the four corners differently. Might that influence the way the car behaves too?

Questions, questions, questions.....maybe I ought to attend Wyotech on weekends

You folks are the greatest!
