KG/MM Springs?

I had bought a set of these off another forum member and I still wanna double check on the springrate of these. He said they were 6 KG/MM front and 5KG/MM rear. Anybody have any info on these or use them? I checked on their site and i couldnt find much info on them (can't read japanise either).

I thought they were teaching metric in school these days.....

kg/mm ~ 55.9 lbs/in

Those springs are ~ 335/280 lb/in springs.

It's a little tough to know the spring rate from looking at a picture of baby-blue springs...

I know they are KG/MM brand springs, I bought them off another forum member, He said they were 6 KG/MMF 5 KG/MMR, i juat wanted to verify his information was correct. I know that KG/MM classifies their springs by color but I can find a shread of information on them. You see where i'm coming from now? BTW these are FC springs.

The brand name is KG/MM ? Heh, you're starting a "Who's on first?" thread.

If you want to verify actual rates, then you need a spring tester, or a lot of weights and a ruler.

KG/MM = kilograms per millimeter. It's not a brand name, it's the stiffness of the spring in metric units.

If you're interested, I've got some LB/IN model springs....

That's the spring rates that I was quoted when I ordered them...I just told them I wanted them LOW & STIFF, hope that helps.

Take some pictures with it installed, I want to see how low it brings the car.
