Hi SK
Can you help calculate my spring rates please. HKS coilovers for S13. Hypermax D. I'm guessing pretty stiff
Not sure what to measure when it comes to the Coil OD's as I have progressive springs. So attached pic for your assistance.
Fronts:
Coil OD lowest coil 82mm/very top coil 82mm. Widest part of OD is the middle of the top 5 coils and that measures 95mm. 5 coils at top close sprung.
Wire OD = 11mm
# of coils = 10.5
Spring Rate =
Rears:
Coil OD lowest coil 87mm/very top coil 87mm. Widest part of OD is the middle of the top 5 coils and that measures 95mm. 5 coils at top close sprung
Wire OD = 11mm
# of coils = 10.125
Spring Rate =
Thanks
Sam
