LCR calipers by the looks of them. (external balance pipe)
sort of looks like an ibiza-r brkt also...
wondering what sort of offset?

323mm disks or 305m disks you planning?
 
i dont mean wheel offset, but caliper offset with respect the centreline of a 305mm ibiza-r brake disk. lcr calipers were 5.5mm different offset to ibiza-r ones
