My Ride: 08 AW M3 Coupe
M3 V1 Install w/ CF roof
So, I just picked up the new M3 coupe on Friday and have already begun to have fun. I looked at the post from Tim330 on V1 DIY, however, my M3 has the carbon fiber roof. Turns out that there are no bolts to which you can mount the ground wire. There are holes in the sheet metal, but after a couple hours at Lowe's I gave up on finding a bolt that would fit. Has anyone else run into this problem yet? So far I have come up with a couple possible solutions:
A. Remove the stock prong thing for the ground wire put a tap on, and just tap into a ground wire.
B. Sand off an area of the metal that is present and just use conductive epoxy or some other type of adhesive to attach the prong right to the metal.
C. Just get a metal screw, and drill it right into the metal.
I posted on E90, but figured I would ask some folks on here...I still look here, so I figure someone that can help still does too.
If anyone has any suggestions or easier/more elegant solutions, feel free to send them my way. Thanks.
