What is the stiffest springs run on coilovers?
Many cars are dual-purpose, some are track only. 16 kgf/mm, about 900 lbf/in, is pretty common. Rates from 10 kgf/mm (about 550 lbf/in) to the 16kgf/mm seem common. However, it would seem that rates as high as 22 kgf/mm to 26kgf/mm might be reasonable, especially for a lowered, track-only car with aero such as a splitter and wing.
What are the stiffest rates that have been run?
Thanks,

On my street/track toy I run 14kg. Ive heard guys running 16kg, but that's about the highest ive come across on this platform. I imagine someone is running higher with dedicated track S2000 with fat race compound tires, but I don't know what. Would be curious to know.

seen 20kg on dedicated race cars, but even then you'd better have a shit ton of aero and hoosiers. Hyperco makes conventional springs up to 3800 lb (67.86 kg/mm)

You can't compare spring rates for one model of car with another. Differences in motion ratio of the suspension are different, car weights are different, which means a 600 lb/in spring will be soft and one car, and very hard in another.
Stiff springs aren't the formula for performance. Stiffer is not necessarily better.
