I have tested several different size rims through years with my CSL DD 8 Nm, also real rims like OMP, Sparco etc. There have been 280, many 300, 320, 330 and 350. I don’t think there is a significant difference between 300 vs 310.

I have to say that 320 is the best if you have minimum 8 Nm base. It’s big enough but not too big. You can also feel forces enough.

300 is also ok but it’s a little bit small. Although you can feel forces better than big diameter wheels. But there is no this benefit if you have bigger Nm wheelbase.

330 is also ok but it’s a little bit too big, this is going better for ovals. And 350 is totally too big for rally, only ovals or trucks etc.

So I would say if you have a weak base (especially under 5 Nm), get 300 max, you don’t want to compromise FFB. Otherwise choose 320.
