Wow this kit is made by fujimi?? I have a fujimi mazdaspeed RX7 kit and it was nothing like your kit! Mine had the mazdaspeed front, rear bumpers, and hood separated, and none of them actually fit the body! Looks like fujimi updated their tooling for this special spirit R....
Very clean build you got there...are you using separate wheels or did those come with the kit? The design is a bit different from the boxart.
