Both tires will be a complete transformation from the minivan tires he is on now.
My impressions of these two tires from my car and driving other peoples cars:

Dunlop Star Spec- Amazing traction in the wet, maybe the best I have driven. Excellent dry traction also. Some chunking of the outer shoulder if driven hard at AX or the track.

Hankook RS-3 - Good wet traction but not show stopping. Phenomenal dry traction even after continuous lapping with no visible shoulder chunking. So far they seem to hold up well in the heat also.

Both tires generate more road noise and have a firmer sidewall than PS2 or Continental.
