Technical Help identifying lowering springs please

[balidey]

I've just bought a set of lowering springs for my cinq sporting, but I don't know the manufacturer.

They are blue and the only markings on them is 17-170-032-HA on the rears and the same but ending VA on the fronts. The claimed drop is 35mm, but not yet fitted them to confirm

Anyone know what they are from the colour and part number markings?
Thanks,
Steve

My spare Apex rear springs are yellow
Witech(or who ever they are) are green IICR

I had a set of JR springs 60/40 = BLUE

Had it confirmed that they're Hormann springs.

Anyone had experience of these?
