The roll center improves very little with changing the SAI by a degree or two
If it were to improve in a linear manner it, which it doesnt then it would be an improvement of 6 mm per degree by this table I made a while ago

*RC height in mm!
Also keep in mind roll center height is not static and it is lowered when there is body roll

You see I added 12 degrees of SAI to get a better RC height, but having 15 degrees of SAI is silly and will cause huge tyre jacking with steering which you do not want in a drift car.
Camber bolts are not a poor solution if they are properly locked
