so today, i finally got these springs tested properly by the guys at Swift, who by the way are awesome!
all 4 of my front sti pinks with the white paint markings (usdm), were ~215lbs/in
the 2 rears with orange markings were ~190lbs/in
the 2 rears with purple markings were ~290lbs/in <---not a typo, 290
these rates, while accurate, can be considered rough because different manufacturers will average their rates at different points dependent on the application.
it makes sense that the higher rate purple marked ones (290) would be shorter than the lower rated orange marked ones (190).
now the question remaining is, with the given rates, what are they?
the orange marks throw me off, but their rates say usdm pinks
the purple marked spring rates say sti tarmac, but i thought those were all black???
please feel free to chime in.
