Was looking through Japanparts.com and came across this. I have trouble with head room in MY05 WRX and now STi when I'm wearing a helmet (I headbutt the roof on the bumps at Collie), so would like to lower the seat.
It will still have to accomodate a shorter driver too.

Anyone used one and does it lower it enough to be worth it? Exploring cheaper options before I just go to MMS and fit a race seat!
