I found my future wheels. SSR Type F's in Flat Black (possibly silver). Similar to Volk CE28's but I actually like these more

Now the only question is 17x8 or 18x8.....Decisions decisions

Don't get 17s, you'll regret it.

My third gauge would be Oil Pressure. You might also want to look into the Defi Link Display, you can have multiple aspects of monitoring with this system. All you have to buy is the individual sensors for the things that you want to monitor. I have a Spec.B so I dont have the cubby but I'm pretty sure that the Defi Link Display will fit in there.

Gauges: Boost and EGT

BCS: Prodrive FTW, I've had nothing but good experiences on all of my Subarus as well as my friends' cars with this piece.

Spark Plugs: NGK BKR7EIX

Honestly, Brembos are good, but Stoptech and AP Racing are in a different league...

 

2-piece rotors will always be lighter, and generally have better cooling

Stoptech may be better than STI Brembos. But, as a fair comparison, you need to compare Stoptech kits to the Brembo GT or GTR kits.
