That Schroth system pictured above is garbage, sorry.
Back when we were younger and dumber my brother-in-law had a similar setup in his Miata. We thought it was the bee's knees because HARNESS. One thing I remember about that idiotic 4 point was that you'd yank on the shoulder belts to tighten them up. Each time you did that the lap belt and buckle would climb higher on your body. Without the sub belt to keep the lap belt and buckle in place they just don't work properly.
I'll also toss out the opinion that if you are struggling or bracing yourself in a stock seat then a harness isn't the right answer anyway. You need a proper race seat, and one that truly fits you correctly. I had a good Sparco seat in my BMW race car and after running it for awhile I realized I was still bracing my leg against the cage or tunnel. I found a Cobra seat that was a much tighter fit and could just drive. A properly fitting seat (combined with harness, etc) will really change how you drive.
I understand for the autocrosser and occasional track junkie changing all of this stuff may be impractical as well as prohibitively expensive. That old adage applies though: speed costs money. How fast do you want to go?
