I run the 4009WHR and 4009W in my WRX. Very comfy and supportive seats (kick-ass memory foam cushions). I use the "W"ide models (I'm 6'4", 210lbs) though I can squeeze into the normal width ones (I was going to get the Wide/Tall models, but they weren't FIA certified yet when I was shopping). I find the W's give me more mobility w/ my legs for left foot braking, double clutching, etc. Since I've got a 6-point harness, I'm not really moving around much even if the seat's too wide.
Keep in mind these are fixed-back buckets... it's tough to use the stock seatbelts w/ them. Plus you will need Subaru specific brackets, sliders, and side mounts for the seats if Duckie's not including all those bits.
