If you want to see what is happening to your roll centre plot it on some paper. One advantage is that you are using a 1/10 scale car, so you could hold the front and rear of the car up against some paper and mark off all the pivot points, move the suspension in increments and mark it again. Do this for all your normal link positions and you will get a plot of what is happening to the roll centre.
Someone at the weekend said you have lowered your roll centre because I had gone to a shorter link on the front, but I could have lowered the outer link height and raised the inner link height and had the same roll centre as the longer link at the same ride height. I would have had a roll centre that would have moved more due to changes in ride height and one that changed camber on the wheel more through the suspension movement.
The weight will transfer to the front through the roll pitch which is the difference in heights of the front and rear roll centres, so normally most rwd weight rearward cars have the front roll centre lower at the front than the rear to transfer the weight forward.
Also the higher the centre of mass the more weight transfer to the front and rear and side to side. If your rollcentre is higher than the centre of mass you get negative transfer of weight about the roll centre as you corner ie the part of the weight transfer equation that is weight transferred due to the roll centres reduces load on the outside wheel. At this point there is still an increase in weight on the wheel due to weight being transferred globally from its central roll centre (where the centre of mass hits the pitch angle between the front and rear roll centres).

Its all a bit of a fluid system so realistically you are back to just trying things out. The only way you could make sense of it would be to work out the G pulled by the model in a corner and record loads of setup data and calculate the load transferred in a corner. Then at some point you might have enough data to find some magic numbers that work on different track surfaces that require different tyre slip angles (that's also a big bit of data missing in the RC world compared to fullsize).
Also you wont find too many fullsize race cars with 50/50 weight distribution as that tended to give inconsistent handling, most seem to have going up towards 60pc weight at the driven end.
