Corbeaus sells brackets as well, same price, however the aftermarket brackets are not up to the task of hard landings <img src="/forums/images/graemlins/smile.gif" alt="" />, sliders tend to bend a bit making it harder to slide them back and forth...

Corbeau and Recaro ive found are very comparable, only complaint about those racing style seats is the side bolster wears out on the driver side, have new foam for mine ready to go back in (warranty covered the worn foam pads) if i could do it all over again, it would be mastercraft suspension seats, those are $500+ each though...
