These have been sitting on my shelf for getting on 5 months now and I am debating whether to fit them or sell them on Ebay.
I originally got the vents only, but later realised that to form the hole in the wing required for them would be extremely complicated - as M3 wings have a hole 'peened' inwards for the clips to fit behind.
I then found the Blackout Shrouds which would then clip behind the wall thickness of the 8 wing. The vents clip into these once the Shrouds are fitted to wing.
Only prob for me is that I really like the way the 'fingers' of the Vents on the M3 overlap the metal, and this effect would be lost using the Shrouds - see pictures. On the up side though they are Black so would match the colour of my car.
I also need to make a fitment/cutting template before my local bodyshop will touch them with their Plasma Cutter
Opinions and/or advice please
