Why don't u get the cp-e intercooler as it comes with an additional oil cooler. That's the one I have. Been tracking my car and no limp/heat soak problems.
Stock calipers are good enough. So just buy street/race pads, better brake fluid and stainless steel brake lines.
U definitely need a good coilover. Get TC Kline with camber plates. That's what I have and very happy. Great performance for price and u can pick your spring rate unlike others
I actually have a set of Endless race pads for sale and stoptech ss lines also, as I bought a stoptech BBK for a good price lately. PM me if interested.
