Wedge Engineering Seat Backets...anyone use them???

Hey Everyone,

I just got a new set of race seats and was just going to suck it up and buy a bracket adapter. Did anyone ever use these?

$105.00 works for me if it keeps me safe and doesn't make me waste a day having a heck of a time custom fitting these seats (APC ).

Thanks
