My car currently has EP3 seats in it with modified EP3 seat rails to bolt into a DC2. I autocross and track my car, and its a tight fit for headroom with my helmet on. Basically Im wondering what is out there for lower seat rails. So far I've found Vision "One Touch" Sliders that are made for DC2's to lower Recaro ITR seats about 2". I think they would lower the seat enough, but I'm not sure if the EP3 Seat mounts to the rails in the same pattern as ITR Recaros. Does anyone have a picture or diagram of either EP3 Seats or Recaro ITR mounting points?

Here are the Vision rails I am referring to.

as long as they are bottom mounted, it should work
