I'm running the new 06+ wrx SMFW and oem 06+ clutch in my legacy. I currently am somewhere around 340whp/395wtq (e85, vf52). I've had this clutch for the last ~20k miles and it's been great. I do 99% daily driving, but the 1% is hard driving, including flat foot shifting. The clutch doesn't have an instant grab when doing flat foot shifting and launching, but it does feel like it grabs all the way after a second or so.
