I’m trying to work out spring/wheel rates and roll stiffness distribution for the Spitfire. The specs of the stock suspension sets it up quite heavily to understeer (much stiffer front wheel rate, much stiffer front roll).
Now that I’m sorting out the rear suspension geometry, I can aim for a more neutral suspension balance.
Here’s the question. When I’m looking at relative stiffness front/rear, am I looking for something that’s roughly equal to the weight distribution?
For instance, my weight distribution is sitting at ~54% front. Should I be looking at a wheel rate distribution and roll stiffness distribution of 54% apiece to get neutral handling (or a couple of percent higher for a tendency towards mild understeer for safety)?
