I've ben told to set the ride hieght on race cars ready to race with the driver in it at 1/3 up from fully compressed

you can use a Tyrap on the shaft at ride hieght and then see how much extension you get on a good track, go from there as long as it is not topping the shock travel out

If it tops the shock travel out get longer ones or slow the extension speed down
