My MOT has the same, last year took it to a place, I had replaced the w brace for an ultra racing one before my MOT because the old one had rusted through, and the mother f@#%er said to me my subframe was badly corroding because the TINY LITTLE BRACKETS that hold the black plastic kidney shaped covers on covering the bolts to the w brace were very rusty, I'm not gunna lie, they were very rusty. I told him about the ally subframe so can't be rusty... he said its connected to the subframe and looks bad doesn't it, if you had painted them before I wouldn't need to put it on an advisory. What a d%@khead.
