I have Corbeau GTS II in my car there not to bad, I haven't had them in the car for awhile I was going to lower the seatpans, to allow for a little more room since my head is just at the cage. Hopefully the picture helps, if you want i can set the seat back in and take some picture with a measuring tape to see how much room is there. <a href="http://s141.photobucket.com/albums/r59/68fbjjz109/?action=view¤t=Picture030.jpg" target="_blank"><img src="http://i141.photobucket.com/albums/r59/68fbjjz109/Picture030.jpg" border="0" alt="Photobucket"></a>
