Are there relationships between lateral and longitudinal forces? Of course. Though you should be careful of what you're calling lateral or longitudinal "grip."Erunanethiel wrote:So lets stay on the subject.
Is there a correlation between slip angle (lateral grip) and slip ratio (longitudional grip)?

Honestly I've had a hard time here following what exactly it is you want to do or learn. I think what would be helpful would be if you can be very specific of what end goal you have that you're trying to achieve, and we can work back through technical details (if necessary) from there. Much easier to answer a question like that than poking and prodding around some technical terms without knowing where you're going with it.
At some point it sounded like you asked.. if you have a low power RWD car and bolt on some UHP tires (Pilot Sport Cup, whatever) - will you be able to drift it? Gut feeling - no. Especially in a production car that's set up out of the box to have some steady state understeer.. put on high traction tires and you'll just have power-on understeer (yes, such things happen).
Here's what a lot boils down to, in simple terms: Some tires have a very easy traction transition and are easy to modulate with steer and throttle on the limit, by a professional driver on a closed course. Other tires have a much more violent and abrupt transition where you push them a bit too hard and just be out of control = wrecked car with amateur driver and with obstacles around.
So taking that and adding to what I said early - is trying to drift around everywhere brilliant? No, pretty dumb and unimpressive.
