You do not need 2" shoulder belts if you mount your belts correctly, Hans was designed before 2" shoulder belts were being used and using 3" shoulder belts allows you to have the ability to use other H&N devices if a Hans does not work for you.

Eugene,
IMHO, you cannot get them too close together. And 3" belts (again IMHO) work better than 2". The original HANS (~1991) had 'ears' on the sides of the breast plates and an area in the upper chest that conflicted with 3" belts. The newer model no longer conflicts - and the 3" belts actually "kinda encapsulate" the MUCH narrower HANS. The 2" belts tend to slide off more easily and you need to be VERY careful at 'belt in' that they are really where they need to be.
I can't imagine a problem where the belt mounting holes could be too close together. I put mine at the minimum (3" inside to inside?) recommended distance and wish they were closer ... but new mounting holes would leave me with swiss cheese in the mounting bar or I would need to replace the bar .. and $$re-powder coat the frame$$.
Edit .. maybe the best way would be to CLAMP your belts as close together as they can get (1.7" ?) and sit in the car with your HANS on and see how it works.

Schroth has some amazing safety guides. Everything from how it relates to the Hans device, to the details and options on lap and anti-sub belts!
I second the sit in the car thing with the belts clamped to the bar for a trial before you drill! I went commando on my car and just drilled it according to the instructions, which happened to work great for me. But it's all about geometry, and how far the bar is from your neck will affect the ideal distance. Thankfully for me, there's a lot of leeway in the measurements!
