Thanks for the input. I was able to source the Ferodo DS2500 pads here in the US. Apparently they fit a number of applications, including some stuff that came to the states. As for discs, I just couldn't swing the cost of the Nationals, especially with shipping. Total would've been over $300usd, so like 236gbp. Besides, I didn't really want the rotors dimpled/drilled or grooved, so I ordered standard discs from Graham Goode for A LOT less.
Thanks again.
