Ah interesting, I was wondering why even with the fender pull the lip wasnt flat and still so thick. Thanks, yeah that sounds like a better solution, ill try that instead of cutting, less chance of accidentally cutting a spot weld too lol.
EDIT- following up, after taking another look at the inner lip, the shop that pulled the fenders pinched the top of the lip ‘channel’ closed, so wont be able to get a wire wheel in there to clear out the rubber :/
There are spot welds are on the inboard side of the U shape, if you cut off the entire channel, your inner and outer arch will no longer be connected to eachother, you can solve that by welding the entire perimeter, which is what I have on my personal car, but obviously it will need painting on the outer arches at that point, you also need to be careful of heat control and warpage.
Another approach without welding is to first cut the U shape into the L shape, by removing the inner edge with the spot welds, and then carefully only cut out the inner arch part of the L shape, not the outer arch part, then apply panel bond adhesive and fold the outer arch over the now cut inner arch, and seam seal it afterwards, that is how a CSL is from factory.
Here is a CSL for reference.Last edited by bmwfnatic; 01-10-2025, 02:58 PM.E46 ///M3 • 12/2002 • phönix-gelb • 6MT

I was tightening the cylinder head bolts and one of them, number 12 in the diagram, was just a little easier on the resistance side than the rest of them. I was still able to get the 30nm+90+90 degrees, I used a snapon techangle, but it just was smooth unlike the rest had which had more of a tight/clamping feel. I cleaned the bolt holes and used compressed air beforehand but now I'm rethinking if somehow maybe there was residual brake clean or I lubed up the threads with too much oil (used an oil can and just went down the threads, not much imo). It could just be OCD. Any experiences with this/insight?

If you marked a line on the bolt, you can come back and check that it is still in the same position in a few hundred or thousand miles to satisfy the OCD. If the cams are in, even more incentive to keep going forward. You also used a techangle and it is hard to mess up with one of those.‘02 TiAg/Impulse Slicktop
