you can but its a pain in the ass due to offset of discs you really need a 355mm rotor and bell to use those calipers

An expensive conversion as i tried on a mates escos,cheaper to find a s/h set up imo

The focus disc will foul the steering arm sorry,you will need a flatter style disc.I even tried a pug v6 305mmx28 disc but theres not enough room for the brackets

hope this helps a bit
