Drive the car hard, really hard, full compression turns with alittle lock im pretty sure this will rub where the arch liner meats the front bumper, i could get my ET32 to just glance this hence to move to ET34, with your ET29.5 upfront im pretty certain this will rub, again depending on tyre size.....The rub i has was so minor i could really call it rub BUT i didnt want any contact, i could just see their the tyre had glanced the plastic, this was with 2 people in the car at full cornering speed.....
