That's the top speed I achieved in kansas, I may have gotten another mph or two if I had kept on it but I had the rear hatch overflowing with stuff that I had left at home when I moved. TV, ebony nightstand, luggage ect. so I had an extra 500lbs and passenger in there. without that weight I feel that it may hit 150, though it may have contributed to it feeling so stable at that speed... As far as I can tell though I've got the top reported/recorded speed record for the 08WRXHey Bad Company I see max speed 141mh as your pic. Have you topped your car out? I have had mine to 139 and it was still pulling. I am kinda curious as to how fast they go.
I had a couple pf rattles coming from the inside. I linked it to the A frame on either side of the windshield and the B frame toward the bottom was rattling (or A pillar and B pillar, whatever those sections are called). I also had to replace the hood b/c of sliding into a mailbox and right under the hood scoop squeaks, it's the plastic piece that directs the air downward, haven't gotten that fixed yet, but soon. If the rattles are coming from the A pillar, then ask the dealer to put something in between the A pillar and the dash, that's what my dealer did and it virtually got rid of it except in cold cold weather.I have a rattle as well. It seems to be coming from the front vent foe the windshield. I took it to the dealer, but he said it was not consistant enough to troubleshoot.
"That's the top speed I achieved in kansas"US WRXs have an electronic governor well under 150 mph
if you're hitting these speeds you're probably going downhill with wind behind you
