Just to bring to your attention article 5.24 in the ACU Road Race regs, page 184, which reads as follows:

"BRAKES. For machines fitted with two front disc brakes the split of the front brake lines for both front brake calipers must be made above the lower fork bridge."

This is not a new regulation, but to avoid disappointment at first practice, I thought I'd make mention of it now. Many new bikes have an "up and over" brake line, which runs from one caliper to the other, straight over the mudguard. No bike will be allowed through scrutineering with this set up. Also, cable-tying brake lines together below the bottom yoke produces the same effect.
