What brake discs are u running David? I had the same feeling of pedal on metal, I had this with the standard brakes. To me its the limitations of a standard brake setup. I also wouldnt run uprated pads (i.e ebc greenstuff) with standard discs, I would use at least 10 grooves for better heat and brake dust dissipatation. I would also recommend installing a cusco bmcs, it will do wonders for positive pedal feel. For a future proof setup, go for a twin pot setup. Then you will be sorted for later on when you start to mildly mod. Thats imho. But before you do anything, make sure to check all functions of the current brakes inc bleeding etc as mentioned above.
