I'm correct in presuming these front wings are plastic?
If so, you may be able to significantly improve them through the use of gentle heat.
Plastic has a 'memory' (i.e. it wants to regain its original shape), and if you remove the wheel & wheelarch liner, then gently warm the inside of the wing with a heat gun (or hairdrier would do), and whilst the plastic is more pliable, push back into the correct shape, then remove the heat & allow to cool (whilst keeping the pressure on) - it should re-set itself.
Sadly no, its steel (I just ran out with a magnet to check lol). I did however, see a vid on youtube, where a guy popped out a dent with a spray can of c02 and a hairdryer! Worth a look if you've not seen it done.
