Getting my 8.4" setup on wednesday.
Just need disc driveshafts, metro turbo drive flanges, fiesta calipers.
I've got some adpaters for the brake lines made up, but i'm looking at this banjo bolt idea too.
When Mark and I were looking at the F-caliper (I have MK2 but I think the MK1 is the same) the brake hose connection sticks straight up out of the caliper, this would mean the hose would need to be bent in an S to reach back to the mini subframe mount.
From what I have seen some people have extended the metal pipe to mount on the inner wing or as Mark was saying you could come off of the caliper at a right angle with a banjo fitting so the pipe follows the same route as the old mini one and will be less likly to foul anything.
