They proposed lithium batteries on RS.1...but it was a disaster for warranty claims so they stopped and not a cheap option either.

To compensate the light nose you uplift the rear a bit and your weight balance is better. kiss

As said by others, the weight location is key and the battery is high enough to be noticeable especially on the front of a 991. You can really feel an empty tank during a track day. Cheap update for weight saving. 

Next one is exhaust...brakes...wheels...and if you still have few pennies left you can go with carbon sway bars from the WP and the cherry on the cake are the gorilla glasses and suspensions. Job done total =-100kg 

last of the last would be roof and frunk in carbon indecision
