Cars w/ lower motion ratios will require significantly LESS stroke.
You only need enough stroke to be not fully compressed on corners and have enough travel to soak up the bumps.
You could rig up shocks like these if you think longer (stroke) is better:
Hell ya I would take shocks with that much stroke!!
Peep this pic:
As others have said...you are wrong about stiffer springs needing less stroke. That car has double height adj Zeal coilovers with pretty stiff springs (600lb all around) and street tires. It has droop travel numbers similar to the values mentioned on the first page by TiC. As you can see...its lifting a front wheel when tryin to power out of curve. Dont know if you race but you can def feel when this happens and it effects the car everywhere. Meaning power application is delayed and steering feel goes numb. Then once the tire lands it upsets the car.
This is where as much travel as you can get no matter how stiff your springs are is need!
Here is a pic of what good droop travel will do for you:
This is a hard breaking left turn and as you can see the inside rear is firmly planted on the ground allowing the driver to get the power down early. I wish I could find other cars going around the same corners for reference but I hope this helps.
