Carbon fibre E46 coupe kidney grilles
This is a pair of re-facelift kidney grilles wrapped in real carbon fibre, not dinoc. They cost over 120 when purchased.
Unfortunately the fit is a bit lose - so the slatted section from an OEM pair or a bit of glue such as tec7 would be needed to hold them in place securely. Its not a major issue, but would rather be straight up about it!
