I used Brembo discs cheap and good..

If you want uprated kit, then I can recommend EBC

Get a pair of their Turbogroove discs, and a set of Greenstuff pads.

Note that Greenstuff are NOT suitable for anything quick or heavy - you
should use Redstuff Ceramic instead, or even Yellowstuff R (I've got these
on my 210bhp 406 Coupe and they're great).
A 2.0 406 is slow and not particularly heavy though, so I'd just stick with
the Greenstuff - it's unlikely you'll be able to get enough heat into the
pads to make the best use of the Red and Yellow.
