Default Are KYB AGX or Koni Yellows stronger than stock WRX struts?

Both the KYB AGX and Koni Yellow (inserts) seem to be popular upgrades for the WRX. They have higher damping rates and will handle stiffer springs, but are they stronger? For example, the stock WRX struts have 22mm piston rods. How does this compare to Koni or KYB aftermarket struts?

Basically, I'm interested in a suspension upgrade, but I like the WRX's ability to do some light offroad stuff stock. I don't want to replace the stock struts with something weaker and turn the car into a pavement-only "sports car".

I realize the inverted 40mm SPT strut/spring combo is probably a better option, but I'm wondering how KYB or Koni stuff compares.

I would say strength wise both the Konis and the KYBs would be near the stock struts. Both of these offer adjustability and superior dampening to stock tho. They are more for on road/track performance IMO.

If you are serious about off roading try the inverted STi struts. Theyre just about a no-brainer for what you want I think.
