I would say Brembos, that's based on cost, performance, and durability, other kits are available from GBE, and Reyland.

The Brembo kit is not a 100% direct swap, you may need wheel spacers and extended studs if your wheels won't clear the calipers, when I fitted mine I wanted to keep the mk2 11 spokes, the problem is they have no clearance without spacers, life would have been a lot simpler if I'd used wheels with more clearance, something like OZ Ultralegs, or Superlegs would have probably fitted without spacers and longer studs.
