Not everybody wants to do track days and not everyone wants to fly into a corner braking at the last minute.
It doesn't matter if you have 200bhp or 400bhp - depending how you drive will decide the need for upgraded brakes or not. I personally used to love the power rush away from roundabouts and corners and i had no need what so ever for any better brakes than my OE 4 pots with godspeed disks (that were only bought because they were a bargain in a group buy). I wouldn't think twice about running 400bhp+ on a set of std brakes as they would be wasted on me

 

OE 4 pots are not bad at all, as long as you got decent pads. Braided brake lines also help.

 

how much power would my standard wrx take then dont have to be 400bhp just getting near it would be nice and as for feeling the power of 4oobhp ive been in many a car my mates built (Mike L) right up to his 750bhp monster he builtv
