This is a little long winded but I Finally converted my stock 2003, 530i bumpers to the M-5, actually M-Technic areo. But not without some remaining issues. I need help from anyone who has actually performed this mod on a 2003 or possibly 2001-2003 automatic 530i. Has to be automatic because the manuals have different parts and the 540's have different parts. There are plenty of threads out there on 540's and one on a '98 528i on BMWTIPS.com but it seems that there are some part differences from one engine/year to another. Here's the existing problems:
1.) Can't get the new engine cover or "screening" part to fit due to the brake ducts are in the way. I finally found the right engine screen/cover because the holes now match up to the holes on the frame. But, I think I need the brackets or intermediate ducts that attatch to the brake ducts to make this fit? Not sure. I'm told now that I have already installed the bumper I now have to disassemble the entire bumper to install these intermediate ducts or brackets but were not even sure these will make the engine cover fit.
2.) On the drivers side fog light opening there is a piece of black trim called the "Frame" that surrounds the fog light and covers the opening around the fog light and fills out the rest of the fog light opening. My car has a duct directly behind this drivers side fog light and is clearly visible and looks unfinished with the piece of trim that only covers the fog light and not the entire cavity. Maybe it's just me wanting perfection?
3.) On the rear bumper: I have a 1" gap at the bottom corner of the bumper and the inside of the wheel liner. Threads are saying the M-5 liners have to be customized to fit on the drivers side. If the M-5 liners are not bolt on and the stock ones don't fit correctly what is the right liner? I know BMW had a Canadian model 530 M package from the factory so what part would they have used?
The dealer or the BMW body shop can't seem to solve my problems and quite frankly, they really don't care. I can provide part #'s if needed but if anyone has performed this mod on this year, model please help.
