However, yes, the engineers in the mother country took all of that into consideration so mucking with the formula usually doesn't net favorable results. Unless you've taken a holistic approach and engineered the entire system. Adding a 50 lb brick to the front bumper is probably not a good idea. The suspension experts can explain better, but something about moment balance, inertia, etc. Again, don't overthink this all. Run the car in well maintained stock form and pay more attention to your skills than the car's set up.

Didn't the factory already go through that evolution?
-64 Short wheel base car
-(later not sure what year) added weight to the front bumpers of short wheel base
-(68?? lengthen wheel base)
-72/73add a second battery up front of the long wheelbase each positioned outboard behind the headlights in battery boxes
-74 big heavy impact bumper up front and move to a single battery positioned inboard.
