Formula 1 no. Formula 5000, probably. I don't have specs on either one nor am I friends with any drivers from either one. But without Aero, I can not see any reason to use anything stiffer than 14K on a road course that has bumps, camber, and traction changes.

In a nice flat Auto X environment I can see the point. 14K spring with a corner weight of ~800 lbs is pushing the limit of tire compliance and would only be good on a very smooth flat surface-like auto X or tarmac. You will not be getting enough bump travel to ensure tire compliance. I don't know the math on bump stop rubbers, but proper bump stops is probably a better answer than 18K springs whether on tarmac or corner 6 of Big Willow.
