You don't 'spin out' in the gravel like side-stepping the clutch from a stop. Locking up the wheels while braking doesn't create the same blast of gravel. Did this with two nicely painted '66 Mustangs during adjustments over the years and not a scratch. The alternative is to make nice skid marks/flat spots on your tires locking up on hard pavement.
Of course doing anything on gravel with an air dam is risky.

*It irks me that Wilwood does not provide this but Stoptech has a good article on this and in graph C you can see what the knee point is. This point of pressure reduction is what is adjusted by the spring in the valve body as you "dial it".
