Kevin2 Alot has to do with alignment and tires. I started with BFG 15" wheels and the steering was ok. Good for the street which I did little and slow on auto cross. Tires where poor all the way around. Poor grip, wear hard, and slip and slide on tracks. Great for smoking burn outs. I went to GT qualifers of Dunlop and the car handled alot better. Changed the caster for the alignment and the car was quicker to respond and feed back was better. After 20 minutes of track time, had no arms left. Called ERA and they installed and setup, an Appleton /sweet rack. The car handles like a slot car with excellent feedback and quicker than me responce. Upped the caster and camber numbers. Car got better. Went to 17" Pilot tires from Mich and the car pulls almost a "g" in turns, .89 with g meter. Had to upper the springs rates 30% in the front and change the compression in the rear end of the shocks. Car keeps improving. Spax shocks are limited with adjustments. Went to QA1 double adjustment shocks. Mich tires are 200 wear and getting harder. over 260 with gauge for testing hardness. Got a set of Nitto 05 with a 200 wear, heated them up and pulled a .98g. Drivers door popped open on the test. I can drive the car hard for 20 minutes and till have some arms left. I think if you check, you will see there are alot of guys running power steering. It's not just autocross and road racing. It's normal street cars.
Does a cobra need powersteering, maybe not but until you have drivin one with you don't know what you are missing. ERA builds a great car, I just wanted it a little better and got it.
