Power steering: Fluid leaks all the time at the track = solved it with a zip-tie and shop towel.
Brakes: I've melted my OE brakes with PFC01 pads to almost "JuniorM3" status. My next mod was going to be titanium backing plates before I got my BBK. Sounds like it worked for you Ricky.
Engine: 30k also and cant believe what an amazing engine this is. Lightweight, fast revving ... and you can go track day to street without missing a beat = S65 FTMFW
Bushings & Subframe: No issues to report here either. And i have my car on the rack after every track day.
