I'm not positive, but I think you have the same height issues with other aftermarket seats (like Corbeau, and others), and they sell Mustang specific brackets for about $150 too, so you are still saving quite a bit as long as they are quality seats. I was looking at the Corbeau CR1 + brackets + shipping = $950, so if you are in for under $500 total that is pretty decent.
Do you think the seat back is very strong (at least as strong as the stock seats)? I wouldn't want a flimsy seat at the track.
Is there a hole in the seat for the crotch strap of the 5pt harness?
Oh, and how noticable is the "Hunsaker" stitching, wonder if they can leave that off, or use black thread...I'm not a fan of logos/stickers in my car.
