5mm, 10mm to be safe.How far do think you need to move the bracket to clear the Tyre? There is usually a bit of movement in those rigid pipes If not a brake specialist will be able to bend/ move it no problem or make up a new piece that f necessary
Great idea. I don't want anyone messing with the brakes who isn't 100% on the impact of the mods. The pipes don't look to be made of the most durable stuff. I reckon that's the way to go.
