Big brake kits

[sfella]

As my vxr8 has been stood for a few years the brakes are cream crackerd, rather than just replace I have been looking at the big brake kits avaliable. Just wondered if anyone knows why the wortec packages are so much more than the walkinshaw kit? The walkinshaw kit offers 380mm discs up front and 6 pot pistons with 4 pots for the rear, including braided hoses this is only c.250 quid more than the 360mm wortec fronts alone. Big difference on quality or stopping power? Cheers
