If you've got the standard 2-Pots then I'd agree they are a 'bit average'... A set of 4-Pots from a '99 onwards car with some decent discs and pads are a good upgrade.
You could go one stage further and add a Godspeed Big Brake conversion to the 4-Pots. If you won't to go further than that then you are looking at K-Sports/Brembos/APs depending on how deep your pockets are!
