The stock rubber will be ok if it's in good shape. It seems trite, but everyone forgets: the tires are the only part of the car that touches the road. Good suspension and good brakes wont mean anything if the tires give up in a turn.
upon recommendation from ppl on this board, I got Dunlop SP Sport A2's about 6,000 miles ago.
