Front ones are quite easy to find over here - the Ford RS200 used them 
as standard (and they're expensive compared to the single pot ones by a 
good factor of 4!). We *think* there are some rear 4-pot calipers but 
they'll be £££££

*correct me if I'm wrong* but I thought that cross-drilling was to 
eliminate brake fade as the pads get so hot they start burning and 
releasing gasses - they do little to cool them down.It gives those 
gasses somewhere to go. There're lots of websites out there arguing the 
case for and against, but I'm personally on the side of solid 
double-walled discs.

The Lotus Esprit uses double-walled vented discs from a toyota celica 
which are the same diameter out and inside as the DeLorean. 
Unfortunately the mounting holes are about 1/4" further out. Very 
annoying when we discovered this!
