New version is up, mind you the roll angle calculation doesn't account for roll bars. But with that data you can guess what combination is suitable, as you can see the front needs less than half the weight transfer to roll as much as the rear and I'm running a 2.5mm bar at the front and a 2.8mm at the rear and the front still rolls visibly more than the rear, it's ok because I'm happy with track manners.

Thank you all, combining both thread's views are a little more than 3000 and it means a lot to me. Any question or difficulty while filling the spreadsheet let me know, also any setup question or if you want to question my method is OK.
