Honestly Matt, just grab a set of R34 GT-t Sumitomo 4 piston fronts (with rotors) can usually be done for around the $300- $350 mark.
They literally bolt straight on; with some trimming to the dust shield behind the rotor.
These are a huge step up from the stock front brakes; I don't reckon your missus will want for more.
Obviously having a greater selection of performance oriented pads will help here too.
Throw in a set of QFM HPX pads; around $90. They bite well from dead cold and run up to around 550deg.
I don't rate EBC car brake pads at all; they're overpriced, and poor performing.
RDA rotors are fine; they also do a couple of budget performance pad compounds if you're trying to keep costs down.
They will look good, and still fit behind most 17's; (the stock Stagea 17's might need a hubcentric spacer if you insist on staying with them).
