SK, can you please calculate the rates for my progressive Apexi springs. Measurements taken with springs on car under load)
Front:
Thickness of wire: 13mm
Number of coils: 9.5 (approx 4 used up due to progressive rate - SEE PICS)
OD of coils: 10cm to 13cm (floor to roof direction)
Rear:
Thickness of wire: 14mm
Number of coils: 10.1 (approx 3 used up due to progressive rate - SEE PICS)
OD of coils: 13cm constant
My ride is a bit harsh, could be due to bump stops though (I have already trimmed the first groove off (~2cm). I'm using bilstein shocks front and rear.
Thanks very much
