With an EPS, I'm not sure there is value to a lot of caster. My 73 (4460) is still stock caster (maxed out) and has a nice feel of not fighting you to return to center.
As a matter of fact because of that I'm not sure EPS is worth the effort unless the car is a wide body?
I'm probably used to the feel of an American PS car and not seeing the difference?` I realize this may be a 180° wrong thought but am still working this out in my head.
Anyone want to loan me theirs for extensive side by side testing? I'll be gentler then the car magazines? I mark 7,000 rpm's on the tack with a yellow crayon so there are no issues.
