no problem, I work as a mechanic so I'm used to picking up on stuff like that
I can't really say much about the ECS kit since I don't have it, the pictures all show the regular M3 bumper but the rear bumper for the ti is different, I'd send them an email asking them to confirm if the rear bumper is the correct one for a ti or not, no point in having it shipped from another continent just to find out it's not going to work.
