For a hot rodder, EPS does appear to have some real advantages over traditional hydraulic steering.

It removes weight from the front of the car and eliminates the possibility of fluid leaks. What weight it does add is more toward the center of the car.

In theory it can be installed on virtually any car as long as you take the frontend weight into consideration. The Saturn Vue that my unit came off of tips the scales at around 3500 lbs and is front wheel drive. I don't think I would put it on my 4000 lb 46 coupe, but something like a 60's Mustang or 32 roadster would most likely be fine.

It can also give adjustable assist. In fact, this is how most cars that have it from the factory are set up. More boost for low speed and less for high speed. If you read that a car has speed sensitive steering it's most likely electric. This boost adjustment is controlled by the car's computer.

EPS doesn't use any real power until it's needed except for the small amount used by the control unit. It just requires a couple of heavy gauge wires from the battery for power.

Eliminating the hydraulic pump on some builds will greatly simplify fitting everything in a tight engine compartment and since the EPS unit is small and can be hidden behind the dash in many cars, it lends itself to being installed in cars that you might not normally even consider. Fenderless street rods come to mind.
