They were easy to install and did move the seat back so my legs were
not all cramped up but it put my head in the roof, I took them back out and I am 6ft.2in. tall, friend of mine is 5ft.6in tried the seat and said it was perfect for him. CJpony sent them quickly no problem there..
I installed these on a 90 Mustang. I am 6'3". I thought they would be great, but they actually made the seat height about 1/2 inch higher and without tilt, they make the ergonomics wrong. I took them back out.
I am 6'5" and puchased a 2000 Roush Stage 2 based on the fact that these would work. They are incredible. Easy installation and moves the seat all the way back to the rear seats. I even had to move them forward a tad. Completely changed the car for me and I am no longer a sardine. One caveat - if you are real tall you probably have long arms which you will need for the shifter. Not a problem just an observation. CJ sent these quickly and easily. Happy Camper!!
