Yeah, just when i was cleaning the car today and didnt see any form of removable pannel to get to a mounting point.
And as you see in the races, they always have them in the same place, but looks more into the bumper then diffuser but guess thats why there is a drop link with stock tow eye supplied in the boot.
so really if you went into gravel and went to low to remove the diffuser, your in for a mission?
