This depends on a range of factors including what seats your using and how you particular kit is set up for the seating in the cockpit area and to a lesser extent the rake of your windscreen.

I've run MX5 seats on the standard runners and these are quite thin through the seat area though not as thin as at least one seat I'd seen in recent times but then this didn't have sliders either.

If you can directly bolt the sliders onto the floor area, that's a start. I have to run plates off the chassis rails and welded bolts upright through these onto which the seat sliders mount. In the GF you have a horrible cockpit shape so it takes some work.

As an example for rego (and speed) these plates just traversed the rails straight. My passender seat lowering has achieved about a 60 -70mm lowering in height and I am very happy with this outcome. Guess it also helps to be a short arse too at 169cm!!

Have fun playing.
