A general consensus after my last two lapping days is I need a more track suitable brake setup. The stock WRX brakes work perfectly fine, but only if I hold back on use and my top speed.
Got a great buddy hook-up on a set of front and rear Brembos and Girodisc rotors (don't mind the surface rust, they just haven't been used in a while):
I'm just waiting on some 06/07 WRX backing plates to bolt the rears on... cheaper than adapter brackets, and stronger/safer in my opinion.
I'm sure I could have bought better pads and better rotors for my stock setup, but this was a better option... just hoping it doesn't affect my autocross times as much as I think it will (more rotational mass = slower AND a much larger front bias than WRX brakes).
