a friend of mine changed to PMU pads from project mju. cost around rm600 for fronts. thats the only brake upgrade in his car, and the braking power is simply phenomenal... superb!
to anyone who has gsr under their hood, i heard from a fren who told me that he changed his intercooler to a vr4 intercooler and the pipping is stainless. everything else is stock like turbo td04, injectors...
