Sparco seat bracket question

[koga_shuko]

Heya guys I just purchased a set of sparco r333 seats and they came with Wedge brackets and sliders. Anyway the seats are sitting super high...im 5 foot 7 inches and my head is almost touching the roof! ive been looking around and cant find a solid answer. Ive also emailed sparco but havent gotten a response yet. Anywho... I know some manufacturers make low brackets but which will fit my seats? Or would it be better to get a base like the one Planted makes and put my seat on there with no slider?

R333 seat bottom is super thick. You're going to sit high unless you can figure out a way to mount the seat directly on to floor pan.

From the looks of the seat, it seems to be bottom mount which don't have good options for off the shelf seat brackets/rails. Correct me if I am wrong but, you'll have a lower seat if they were side-mount.
