that trick only works for r32's that have the hydraulic hicas.
i ripped my stockers out on the weekend, looking at them, they are only 8mm each! replacing them with 2x -6 feed and 1x -8 return. just use a pipe bender to bend the tube into shape, shouldnt be all that hard
also if u wanna get rid of the stock rubber gear in the engine bay and kepe the stock tube lines under the car, u can use speedflow fittings from the tubing to braide, piece of piss really
