If the suspension is tuned properly, understeer may not be as pronounced (i.e., it may still be there, but it won't be as bad).

A skidpad figure is really a tire test... Because the IS300 has Bridgestone RE040's (similar to GS400's RE030's), I'm sure it will hold the road well. However, because it's nose heavy it may have a greater tendency to understeer more heavily, thus hurting its times.....
