Well, as for the R having the same suspension as the NSX, although it is somewhat true. All I can see in commom between the two is the double wishbone suspension (Dealers would also say that the NSX has the same suspension as an F1 car, go figure). Well, basically if you have a good suspension, your likely to wear out your tires quicker because the car is actually using more of the tires capable traction. But I'm thinking...even though the suspension is stiffer, and the tires don't skid as much, then shouldn't tread wear be improved? Eh, tires area such an subjective area...
