I looked at these again only yesterday @ Amethyst.
They have 2 sets in stock..
The only catch with them, which makes me um and ah... is the rubber seal which goes between the arch and the plastic extension bit.... Its black. Clips to the inside face of the arch.
I was thinking about them myself, but colouring coding them from their black, as supplied, finish to yellow (for me) would be negated by the black line which would show the arches are being add-ons.
Not sure how well they would fit without the rubber thing. That would cure the black line problem... Black car = no problemo.
Looks kinda like a Saxo wheel extension...
I could'nt make my mind up...
did'nt like the price either tho TBH.
