Is there any thing like M3 Hood for E46 4 door sedan which is not made of carbon fiber? Otherwise will need to sprayed into car body color unless its black body.
what do u mean retrofit? Carbon fiber one, i prefer to have same body color- silver. Otherwise i will need to spray carbon bonnet to silver...wasted the coolness of carbon fiber.
i have been talking about original M3 bonnets fitting to a Sedan body.
So to retrofit, you have to get the M3 bonnet sliced in the middle, shave off whatever you need from both sides and rejoin the 2 sides back together to get the correct width.
Unless as Marco mentioned, get an aftermarket bonnet that's already been redesigned.
To my understanding, aftermarket bonnets tend to be CF. Unless you go for a Vorsteiner bonnet.
