Kind of a tough thing to describe. The 24:1 steering box is easy to steer IMO, but it depends on what you’re used to. The 16:1 box requires a significant amount more effort. I wouldn’t call it difficult, but some might. And it’s dependent on your alignment, size of your front tires, etc. And what you’re used to. I have a 16:1 manual box on my Duster with 275/35/18’s up front and +6.5* of caster and I like it, but if I had to parallel park it everyday I might form a different opinion. Below 10mph you want to have a plan for turning and parking, because dry steering it when you’re not moving isn’t going to be something you want to do.
PST is selling a 20:1 box as well, just FYI.
