Hey guys. sorry i've been away.
I have two othe threads, but they are on the bimmerforum. Not sure if i'm allowed to post a link?
To get the wing flush, i did the stitch weldin with a really low amperage welder, thinnest wire (0.8 mm i think?), and about twice as much gas on the mig as you would usually have.
THis was because i was warned by multiple people who said icouldnt do it, that even if i could i would deform the panels from the heat.
So i stitch welded it as you can see here.
To get the wing flush presented its own problems.
I pepped the inner wing like this?: -
By running angle grinde with a big stainless steel wire brush on it, to get a clean 1+ inch clean bit of metal.
I kept trimming the wing up with 1mm cutting discs off ebay (be aware these will spit and embed grit in your forehead!!!!!)
and once i had a good dry fit
i then had to knife edge most of the edges. THis was the difficult part. As i sharpened each edge to make it blend to the wing (basically i ground the back edge from each joining face on the m3 wing),
i made the metal thinner, which naturaly made it even harder to weld.
oh, i forgot. cut the original wing high, and weld the skins back together. Have a friend in the boot ready to blow out the insulatin that keeps catchign fire (its not serious).
When you cut the outer arch do not do it exactly as i did it above. I should have cut just the outer face, and left it almsot like this: -
because i could have then welded the existing inner arch to the innder of the new m3 arch. As it is now, i ended up putting cuts into my welded inner arch, and be nding the tabs out to fit my m3 inner, but i will have to add additional metal in now.
The m3 front arch is rather simple.
I fitted the saloon arch to the m3. Its the same except for the bottom.
clean the original arch up.
dry fit the m3 arch
it will fot something like this.
cut the bottom off of both arches, and tac the normal bottom of the wing ontothe m3 wing whilst on the car like this.
then take it off, and weld together like this.
and then
done! Hopefully your welding is better than mine!!!
Fuel flap i have no pics of uploaded at the mo.
But what i will be doing is buying the m3 filler neck, so it fits to the original wing. The only thing you have to do is cut a nice hole in your original wing so that you can re-locate the central locking solenoid for the filler.
I intend to make up my inner arches below, and then bond a section on around the inner fuel flap (on the original wing). after that i will pump in expanding foam to help stop any vibration, and minor dents, it will also make the whole rear end better possibly, and not weigh anythign compared to the extra wings.!? besides its cheap stuff!
I'm actually glad i did it this way, as the e30 doesnt have enough weight at the rear, considerign the weight of the m30 up front!
hope this helps you guys.
Here's a few recent pics to show i am still doing it!!!
and im still looking for a front m3 bumper re-enforcer/ support if anyone has one!!!!!??????
but its in fibre glass 
, just wondered if anyones fitted an m3 kit? i'm trying to find out how much the metal rear arches are?
