I've never seen our drums warp, so this makes me wonder if they tried 
to turn them and got them off-center. It's almost never good to try 
to turn our drums or rotors: There's very little meat there, so 
removing any is a bad idea. If they rusted due to being parked a long 
time, they can be cleaned up by hand and some coarse emery paper.

My take on this is that they may have turned the drums and ruined 
them.

You need 4 hole drums. These MAY be okay, but the only aftermarket 
drums I've seen had a center web that was about twice as thick as the 
OG drums. This meant that the lug bolts couldn't get all the way into 
the hub, so the threads in the hub eventually stripped out. The only 
way to fix that was to replace the drum AND the hub with good used OG 
parts.

I have good used OG drums and relined shoes. They would be cheaper 
than the parts you found on line. I don't know how thick the web is 
on the socalautoparts drums, but the OG parts have a web that is 
about 1/8" thick. Don't let anyone install thicker ones on there. 
That's just asking for trouble.

If your shop turned your OG drums and screwed them up, that's their 
fault. They should have known better, but then again, you said they 
weren't really a VW shop, so maybe they have a good reason to not 
know.
