danpiu,
A couple of friendly suggestions for safety:
Though your belts are routed neatly… According to the SCCA they are not routed correctly (More stringent belt rules are a result of the Dale Earnhart crash). The belt should run under the bar first, then through the buckle, then back through the rear slot of the buckle again.
This will also allow you to finish the job similar to the way you have it now. The mandate isn’t that you need to start above or below the bar, just that they want you to route through the buckle twice.
One other thing- they suggest that you somehow tie the two buckles from spreading; I use a strong but lose zip tie.
The “Rev” is the smallest of the seats (Also what I use) most people would be too big for it, so on the other side I put the largest seat “2000”. It matches perfect, just has the embroidered 2000 instead of Rev. This way I can also swap seats if someone like Cunningham drives the car.
