How about moving all drag racing equipment ~150 ft north then repave turn 10? That way bikes are straight up and down when they get to the new slick spot. That first 150 ft of west wall could then be moved to the end of the strip. No major configuration changes needed. Some staging/procedural changes could make up for the tower not being moved if its use is crucial for drag racing.

Nice job removing the T10 guardrail. That's one less airbag to setup, keep inflated, and tear down across a race weekend.
