Finished up the Karbonius CSL center console. The most effort required in doing this install requires a lot of rewiring/extending the mirror switch that's on the door, and running it into the existing rubber boot on the door to maintain a proper seal. Other than that, it works perfectly fine in the new position!

Any reason why you can't/wouldn't want to epoxy and rivet the roof bow in? Would make this job more diy friendly if it was done that way.2002 Topasblau M3 - Coupe - 6MT - Karbonius CSL Airbox - MSS54HP Conversion - Kassel MAP - SSV1 - HJS - PCS Tune - Beisan - MK60 Swap - ZCP Rack - Nogaros - AutoSolutions - 996 Brembos - Slon - CMP - VinceBar - Koni - Eibach - BlueBus - Journal

Thanks for those pictures. I've been trying to find a close up of how the bow attaches to the pillars without much success for a while now. Car is going to look awesome, can't wait to see it finished.

another route would be to drill holes IN the roof bow so you can spot weld through those holes into the pillar.
We chose to stitch weld, it wasnt hard and it was quick.
i did consider panel bonding in the roof bow if welding wasnt an option. I'd honestly want to talk to a reputable body shop first to get their thoughts on that though.

Technically the bow is supposed to be spot welded in place and it ties into existing spot welds of the other sheet metal but its not possible because of other sheet metal prevents you from getting to both sides o the sheet metal for a successful penetration.
Rivets would only be used to hold the bow and ensure that the epoxy dries at its optimal thickness for max strength, so those wouldn't really be structural once everything is cured. If there's enough of a contact patch, couldn't you just drill the holes for the rivets in places that don't interfere with the existing spot welds?2002 Topasblau M3 - Coupe - 6MT - Karbonius CSL Airbox - MSS54HP Conversion - Kassel MAP - SSV1 - HJS - PCS Tune - Beisan - MK60 Swap - ZCP Rack - Nogaros - AutoSolutions - 996 Brembos - Slon - CMP - VinceBar - Koni - Eibach - BlueBus - Journal
