Hi, I've got the same springs, 15mm rubs at the front, as does 10mm just about (under really heavy dips), even with the little winglets removed. 10mm rubs a little at the back but would be fine if you remove those little winglets.She is indeed! Lowered on eibach Sportline springs and I’ve just ordered 15mm spacers front and back to film the arches
As for the winglets, no one had determined what they are for, however I have noticed they sit over the end of the metal panel. Its rounded off but could still damage a tyre.
