This was helpful. I’m shopping to get the sparco qrt and was optimistic about getting a slider for the same reason you wanted it But looks like fixed mount might be the way to go.
On my C6GS I ended up having my race shop lower the rear of Corbeau bracket mounts and that helped get me lower. Even with that I still sit higher than the OEM seats. Part of me wants to mount a race seat on the OEM bracket to see how low I can get.
There’s a way to bypass, see towards the end the of the thread www.corvetteforum.com/forums/c7-tech-performance/3918452-c7-race-seats-and-airbag-light-4.html
