More Than Adequate Power Steering
The power steering rack is a Woodward power steering unit. The owner, Tony Woodward, is a long time circle track racer and has developed these steering racks to adapt to a wide spectrum of applications.
They are adjustable/tunable which is why it was chosen for this application. Steering weight, feedback, and ratio/quickness can all be changed easily.
They are also extremely strong and can handle very large corner loads.
Even better, the racks are made in the U.S.A. straight out of Casper, Wyoming.
