are you allowed to use seat sliders or do you have to have your seat set at one position. i am trying to see if i have to make my seat mounts adjustable or if i have to make them fixed. also if you do have to have them fixed, are the required to be roll cage mounted or unibody mounted? thanks

Yes you are allowed to use seat sliders. I have them in my rally car. But you must use a fixed back race seat.(none reclinable) And all seats are recomended to be mounted to the factory locations. Hope this helps.
