Carbon Fibre Wing Strakes

[Beoon]

One of the wing strakes on my V8VR is a little bit tarnished.
Would anyone know how easy it is to replace them with the CF wing strakes (AM parts are circa £400 online).
Removing the front wheel and wheel arch liner suffice to get access?

If the wheel arch liner is flexible as Luna says does the wheel need to come off or can the liner be removed with the wheel in situ?
