It seems like the spring rates are being changed from stock ratio of 3/1 rear vs front to 2/1 rear vs front with the upgraded coilover package.
MJR went with the 336 and 672
Subie went with 450 and 900.
Stock 145 and 460 = 3.2/1
I wonder if this is the proper ratio with the 2/1.
Subie do you have an X-drive or rwd?
