DougM - No we do not carry Carbotech pads. We only carry Ferodo pads for the STi/Brembo brakes. Check your PM's, we'll give you a quote for the Ferodo DS2500's F&R + SS lines + 1.5L of Ferodo Dot 5.1 fluid.
SUYA - We haven't tried these lines on the FHI 4pots, if their line lock mechanism is the same as the Brembos, then you could definately use them.
TheMadScientist - The NASIOC/i-Club member discounted price for the lines is $179US -> + shipping *for payment via MO, CC via Paypal only; subject to 5% equalization charge*
