Galant VR4 kg/mm spring part numbers

My buddy in japan sent me this info incase anyone was interested in other springs then the ones available here....

 

[G]

so the fronts are $170.00 & the rear are $145.00 or is that msrp ?
51mm drop in the front 43mm rear ?
progressive ?

 

i guess not sure the yen rate conversion now adays.as far as being progressive not sure u have to look up the specs on dr21 springs. im not selling these just giving the info out incase u have axcess to kg/mm springs u have a part number to order with. by the way kg/mm are great springs ive used them in all my cars...if i wouldnt have already bought the whiteline springs i would have ordered these.
