What should I negotiate for at Facebook

*updated*

Recently got an offer at Facebook reality labs

Level - IC5 (hardware)
Base - 179k
RSU - 250k over 4 years
Performance bonus annually is ~25k

Location Redmond, WA

How should I negotiate?
Should I ask for more base (190-200k?) or
Ask for more stocks? (300k?)
Or ask for a signing bonus? (How much?)

Please share your thoughts with figures! I’m interested in increased net worth at the end in 20-30 years. Have no preference between stocks or liquidity currently.

Appreciate it thanks.
