80/10/10 is about right.
The difference for me between a really badly setup car (ie major over- or understeer, unpredictable bump and jump handling) and a good setup is 10% at most.
Difference betwen cars is even finer - I don't think I have ever made a difference of more than a couple of percent to my times by changing car - but that's because I usually have competition cars anyway. Give me a Tamiya Sand Viper and the difference might be 10%. When I run my Tamiya TT-01 at club touring meetings for fun, I am only about 15% off the pace of competitive 10.5/19T cars, with a car that is arguably much worse and has a lot less power.
So that leaves 80% (at least) for the loon behind the sticks.
