Steering ratio doubler advice.

If You've got power assist that keeps up with the steering gear controls, there is simply no such thing as 'too fast', unless You're running rallies etc. where You're getting bounced around....that is last thing I would be worried about. The last years of the Shelby Daytona/Z's were barely over 2 turns lock to lock, & My 1st 'hotrod' 7hp B&S homemade go-kart was 1/3 turn lock to lock....yeah..no power assist there.....
