Depends on chassis, calipers used and bracket (quote is for S13) for brakes in general our brackets are made for brembo 4 piston calipers these run for V$375 a side, the other second most popular is 326 Power which is pricey due to the brake calipers but the bracket is V$440 a side. 1 year warranty on all of our brackets to insure customer satisfaction.
I'll be at work at the dockyard until 15:00-16:00 hours, I am sure one of the other guys can wrap up the deals!
(RP bomber right here, if you can't get the dual caliper script/attach line solved I'll send you one or help make one fast once I am home)
