I used our personal baggage and family gifts to achieve a full load as described above on April 1 that included what the rear seats folded flat but without obstructing any rearward visibility could accommodate. I would estimate that it was 350-400 pounds plus an overweight driver and a passenger whose weight I shall not categorize. It produced a pretty good ride. The gifts are gone now and the ride is still pretty good. You might follow the suggestion above that 100-150 lb. would be a good starting point but “season to taste.” Whatever weights you use I would think centered but as forward as you can get it. However, even with a full load in my case above, the car did not feel “tail-heavy.”What do you all use to add weight?
Ie: gym weights? Sand bag? What?
