Default Multiple HKS coilover models for GS??? Help quick.

I ran across a good price for some HKS HiperDamper IIs but I am trying to find some more info.

The model # is 1760-ST007 and matches what is on the HKSUSA website.Here:

I've also run across some other models for the GS:

#1770-ST002
Here:

and #1722-ST007
here:

Is one of these an older model? Different spring rate?

I'm guessing if there is a Hiper Damper II, there was an original Hiper Damper? What are the differences?

Thanks in advance and I put this in the wrong spot for quick action.

Late

I called HKS and got the info.

You are right on the LS and Hiper.

The LS has spring rates of 8/8 kg/mm and the Hiper has rates of 10/8.

I guess that other model number is a fluke. That is the one I was really unsure of.

Thanks.

Ryan

1722-ST007 are Hipermax (Hiper) Dampers. They were 10 or 20 way adjustable. There were 2 production runs on these. If the label on the damper said Hiper-D, then it was 10 way adjustable. If the label said HKS Damper, then it was 20 way adjustable.

1760-ST007 are the current Hipermax Dampers currently available by HKS, also known as the Hipermax II. These are 30 way adjustable and have different spring rates & valving than the previous versions.

1770-ST002 are the new Hipermax LS and are height adjustable only. Lower price too.

All of the HKS kits include the upper pillowball mounts.

Hope this helps.

Excellent writeup.

Mods, can this thread be merged with the "Are HKS yadayada any good"?

Thanks.

I have had the 1722 and the 1760 versions, and will be using the 1760 version on my third GS (Yes, I said third). The 1722 versions were a bit at the mid setting (out of 20). I like the 1760 more due to the wider range of settings (30) and the slightly different spring rates.

The 1770, Hipermax LS are a great option for ones that dont want the extra emphasis on performance (hense the adjustable stuffness), but will be more than happy with a coilover that offers height adjustment and sport enthused ride and handling at a fairly good price.

Just my $0.02

<side note> pillowball mounts are not a race only part and do not damage the chassis nor make you lose fillings. They do offer crisper steering response and a solid turn-in feel
