Is it ok to run the flexi brake line directly from the caliper body to the car, or is some other bracket required in between?
Pictures welcomed, thanks.

Was OK for me when I put my Robin Hood through an SVA. Don't think the IVA will be any diffeent in that regard. The only thing to look out for is that the hose isn't stretched too much on full lock ( and that it doesn't get caught in other suspension parts on the other lock)
