I have priced everything up pedal box, hoses, cylinders, remote servo, remote reservoir ect and like you say It is nearer the 2k which for a fast road and track car prob wouldn't benefit. There would also be fab work needed on the shell! Think I'm going to use the standard pedal box and servo with braided hoses and a bias and like you say use a decent front and rear disc and caliper setup!
Cheers
