My experience with 122s and 1800s is that low profile tires is that they cause the car to track poorly on uneven road surfaces. That's why I went with tall 70 series aspect ratio tires on the 1800 when I had to go wide enough to fit the rims. It drives fine, but on the same car with the same alignment, 195/60-15 tires on either 5.5" or 7" wheels (tried both) were pulling me all over the road.

For autocrossing... yes. Lower profile will getcha better potential results. But for a road going only car, a bit taller is better in my experience. I expect the tracking issues could be sorted with exactly the right wheel offset and perfect alignment, but the tolerances are much much tighter.
