The only thing more enjoyable than driving my GTV on the street with 185/70-14 tires, is driving my Giulietta on 155/15's! The narrow tires give you incredibly light steering with great feedback. But if you plan on being in a hurry (i.e. track day), I'd put more rubber on it. My '74 GTV has 205/55-15 Bridgestone Pole Positions on it, and has done numerous track days. There is NO evidence of any damage to the steering box or mount. I did break the Burman box on my old race car, but that was with 225/50-14 race tires. And the failure happened in the PADDOCK when I was PUSHING the car. To avoid stressing the sheet metal around the box, I think the most important thing is to make sure the bolts holding the box are always tight. If it gets loose and flexes, then you will have a problem.
