Bucket seat ideas
Dude, you can't go wrong with summit high back racing seats.
For $300 they look great, comfy, adjustable seat back and have track sliders.
Good neck protection if you get rear ended and higher than most buckets can go.
You being 6'6" , your options are very limited.
I suggest you go to summit if you can and sit in one of their display seats to see if they will work out for you.
I love mine but you got a few inches on me.
