Took things apart tonight to do some adjustments and weigh individual things.
This rig of Sparco base/slider/side mounts weighs 19lbs! All together with the seat it is over 37lbs (my stock seat weighed in at 43.2lbs). Going to look for a lighter alternative, too dang heavy. I think the Buddy Club mount/slider is a lot lighter.
For the meantime, the seat is back in the car after making the adjustments. I moved the slider all the way forward on the side mounts, the seat all the way down in the side mounts, and then re-aligned it all. Also attached the stock seat belt as well as the harness and re-installed into the car.
Oh, and I took out one layer of the padding in the seat itself to sit lower and now I have ample headroom with my helmet on. The Schroth harness is a bit more difficult to tighten at the waist now, but not a huge deal.
