Call Bobby Archer! They sold me my EVO2 seat and custom brackets that the side mounts bolt to. The brackets that bolt to the floor (custom brackets) are expensive for what you get but are custom bent to fit in our cars. I am 6'4' and 220 and fit perfectly in the seat. The EVO2 is 1.5" wider than the EVO which I can not fit in. My seat will not be adjustable. However, I think that Sparco makes a kit that allows adjustment. I have yet to install the seat. Just got my roll bar yesterday from BTR. That roll bar will allow the seat to go all the way back. The Autoform bar does not. Hope this helps. Again, call Bobby. Oh, you will need to trim the left seat wing (seat cover comes off and you trim the plastic)so the door will close.
