The mivec & non mivec brakelines are the same, no difference. All FTO models have the same rear brakes and the front brakes are single pot on GS/GR and 2 pot on GPX (I presume GPvR too).
Ricerocket can supply, also see Camskill (

You going for the stainless steel braided ones? Got those myself, made a difference to the braking alright.
