Evo callipers have the banjo bolt fitting on them though, vr4 callipers don't. Best to match the calliper with the type of brake lines you have unless you plan on getting new lines made up.
Its just a case of trimming the thread down on the stock banjo bolt 4mm, as vr4 calliper has a shallower banjo thread hole that's its, I've fitted a ton of VR4 twin spots to cars and that's is all you have to do, nothing else.
