if you still have warranty, take it in. should be covered on the 36/36 factory warranty.
if not, I'd consider replacing seat and brackets with a performance seat, there's lots of them around in different price ranges. you'd get better support and drop a little weight off the car. Some Mondeo models in Europe come with Recaro seats. It'd be nice to get a set of those, or the recaros they're using in the Focus.
