Here are the factory spring rate differences per car model. Source is the official SACHS Performance Coilover distributor in Japan, so it looks to be a quite reliable source.

Car model Front spring rate (N/mm) Rear spring rate (N/mm)
TOYOTA 86 ( MY 2021 ) 28 39
TOYOTA 86 ( 1st model ) 23 33

Car model Front spring rate (N/mm) Rear spring rate (N/mm)
SUBARU BRZ ( MY 2021 ) 30 35
SUBARU BRZ ( 1st model ) 23 35
