Brakes, its all down to how much you want to spend, remember your brakes are only as good as your tires!
Another thing to consider is it to coupe with your power now or are there any other long term power gains you are looking for such as 260bhp+
I use mintex 288 discs and pads, with some uprated castrol brake fluid followed by all steel braided hoses *back and front*, the difference is brillaint, no spongyness, and the braking is sharp.
As for your power, remember, humidity and temperture also effect your performance, Such as earlier this year on the roads it just pulled and pulled in comparison to this weather. So do expect the performance and response to keep shifting all round the year, unless its really effecting performance, such as rough idle/stalling or no boost then its a pipe loose somehwere.
