My car is street/strip and needed a headrest so my noggin is not bouncing off the roll bar... installed the cheaper procar seats, which seem good for the money. Bracket has three settings, but you need to cut the top half of bracket to use the lower mounting hole.

Feels similar to stock, maybe lower since the seats are reclining. When car is back from the roll cage shop, I can get a measurement from seat to headliner.
