These may have already been suggested, but here's my $0.02.
1) More audible cues as to what the tires are doing. Also, more progression with in the cues. Tires make a distinctive scrubbing sound when pushed and only squeal when really taxed.
2) More track surface feedback through FF. Since there is no 'seat of the pants' feedback in computer simulations, high resolution FF becomes even more important to the overall experience. An example is when going across bumps in the track, the visual cues are definitely there, but the FF (at least in my case, Logitech Momo) did nothing.
3) This only really applies to open wheel cars, but visual cues on the tires themselves as to their condition. (A minor suggestion)
