I've been talking with the guys at KYB and they sent me this in an email, thought some of you guys might find this interesting:
QUOTE
The AGX products have the following approximate damping force values.
When adjusted, both rebound and compression damping forces change.

Setting#: Relative Value
1 - Same as Factory 100
2 - Same as our GR2 products (10~15% firmer than Factory) 115
3 - 50% firmer than #2 172
4 - 30% firmer than #3 223

For an eight position adjustable product, the damping force values are approx.
the following:
With #2 being Factory at a relative value of 100,

#1 = 95 (5% softer than Factory #5 = 143.5 (43.5% firmer than Factory)
#2 = 100 (Factory damping force) #6 = 172 (72% firmer than Factory)
#3 = 107.5 (7.5% firmer than Factory) #7 = 197.5 (97.5 firmer than Factory)
#4 = 115 (15% firmer than Factory)(GR-2) #8 = 223 (123 % firmer than Factory)

Interesting. That would make it look like the Gr2's are actually a little better than an OEM replacement... (not a lot, but it could be noticeable)

Well I've got the gr2's and noticed a difference. Of course, I also put on eibachs at the same time so I can't be positive about how much the kyb's did as opposed to the eibachs. However, the gr-2s can be found for really good prices too!

^^

not to mention you were replacing old and worn struts.


even a OEM hyundai strut would have felt great if it was brdan new.

i think our stock struts might have actually been tokiko's or kyb's from the factory, i thought my stockers had one of the two stamped on the housing. (might have been my probe though)

cool to know.

a lot of people slightly overdamp in autocross without touching springs. stiffens up the ride a bit and still keeps the car in the lower class.

GR2 struts are like OEM replacement. That's not a real performance upgrade.
Use KYB UltraSR fing02.gif

^^^thats why on KYB's website they dont even list them as a preformance upgrade. check this out http://www.kybsport.com/home.html

no mention of gr2's at all only agx/ultraSR/and monomax.


if your going to do preformance upgrades then make sure the parts your buying are actually preformance parts and not OEM replacements.

I only bought them as a oem replacment when I bent one of my stock struts. I didn't expect much "performance" out of them for the price (which was great!)and considering they are kyb's bottom of the line model. I happened to come across a sweet deal on some eibachs about the same time so I figured I might as well change em both at the same time.

What kind of info do you want on the eibachs zoned? Specs or opinions?
