I don't doubt you know, but, then again, so do I.
I have owned cars with regular style wheels and tires and High Performance types. And yes, they can ride a bit rougher, but is mostly due to the suspension set up. Stock on Stock is, well, stock. Modified wheels and tires on stock is a bad idea, and even worse on cobbled together suspensions, like the cars you posted.
Well thought out and engineered suspensions usually handle most driving and can be set up for street or track. The days of cutting or heating coils, air shocks and long shackles are dead, unless that is your thing.
But to compare what you posted to what I posted is like comparing rocks to feathers, not the same.
