What did you do for your M3 today?

[stash1]

haha yeahhh I haven't driven the car in a long time and they got all rusty after the wash. I'm gonna assume the first drive it will be back to normal.

Ya, that's what they all look like after a wash...if you let 'em sit for anytime. Yep, a quick drive will clean 'em right up.

Started the rod bearing replacement job. Not too bad, had the oil pan off in a little less than 4 hours complete with beer breaks!

-status gruppe coil overs + reinforcement plates
-CSL style wheels

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!

Got the roof bow welded in this morning. Friend is a mobile welder and made quick work of it. About 15 min total done.

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

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.

Today, I stared at it, intently and admired its beauty.

well you cant rivet it in because the places where the new spot welds (the places you would potentially drill holes for your rivets) WOULD go on the chassis, there are already spot welds in the existing sheet metal for other sheet metal so you would be drilling a hole through other spot welds. 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.

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.

I know this is different between the sedan and coupe, but are you saying there are only a couple points of contact between the bow and the pillar (where the spot welds are)? Looking at pictures of the bows makes it seem like most of the surface area on the "ears" of the bow comes into contact with the pillar, as they look contoured to match.

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?

Finally replaced my original 205k mile hood struts (aka hood droppers). All of 7 minutes and makes such a difference
