I'm running stock EVO IX Brembo's. OEM pads and rotors for now. 1" GS Galant master cylinder stainless steel lines. Motul RBF 600 brake fluid. No adaptors, had a forum buddy from Australia ship me a pair of JDM 8g Galant knuckles.
I'm pretty happy with them. With the stock pads, they don't have nay more grab than my old dual piston GSX calipers with ceramic pads had, the brake force is very progressive. I imagine once I switch to ceramics they'll be neck breaking.
