I got Brent at SMD to fit my ksport 8pots.
On my newage WRX we found the brackets didn't line the caliper up 100% central to the disc, so it needed spacing slightly (it comes with the washers to do this). It wasn't far out - we're talking 1-2mm max, but we wanted it spot on. If its not dead central, the pistons will have to travel slightly further one side of the caliper than the other.
Just something to watch out for
