Default Kyb agx vs gr-2 (wrx)

Hello everyone,

i want know if the difference of price between the KYB AGX and the KYB gr-2 wrx specific really worth it? I'm looking to buy wrx gr-2 with rce black spring or the kyb agx with stock wrx spring or rce spring. Do anyone have this setup? how it ride? i want something that is not to bouncy and i don't really matter about comfort. And with the rce black spring how much drop i'm looking at?

thanks everyone

I'd go with the AGX at very least, but strongly recommend D-specs.

AGX has 4 settings. D-Specs are continuously variable within their adjustment range. Makes it possible to tune the struts exactly to the springs.

Check out the tail end of the "Roo II" journal in my signature.

Which RCE springs? They make a few. Pretty much all of them will be too low, none will work well with GR2s, but AGXs or D-specs should be capable of handling them.

I'd recommend Swift Sport Springs (progressive rate firm yet great for DD), Swift Spec-R (a stiff single rate) or what I have, the ProDrives (progressive rate) if you can find a set. The Swift Sport and ProDrives are a great compromise between OEM marshmallows are the stiffness of Spec-Rs.

I ran those springs and do not recommend it on a Forester unless you really know what you are getting into. RCE blacks would be the tallest spring they offer and some run them on Foresters. It will require a strong aftermarket strut and roll center kit to correct geomerty at the very least.

With GR2s, you can run stock Impreza springs. The so called Pink wagon springs (same rates as stock STi springs) could work, but will be a bit oversprung. The Swift WRX wagon springs are nice but too low for our cars, I ran those too.

It is not what you want to hear, but it is the truth.

What is your goal and budget?

If you want to get low and don't mind the harsher ride, you could get a set of d-specs and use RCE black springs. JDM STi pinks (the real ones, not the wagon Pinks) would also be very nice, I ran those. Swift R specs would be another choice in this category. RCE wagons are about as stiff, but lower, so I wouldn't go that route personally, but with 1/2" spacers it may work okay too. You would want a Roll Center Adjustment kit with these options, camber bolts aren't necessary. AGXs would probably work okay with these springs too, so will OEM STi struts but you'd want them rebuilt by Feal as they are very old by now.

If you didn't want to get as aggressive/expensive, you could get GR2s and try them with OEM STi springs, or the wagon pinks (same rates). It's a bit too much springs for GR2s, but some do it. Honestly, if I were to consider GR2s, I'd get them in Forester fitment and stick with Forester Swift springs -- it will be a bit higher, but will work a lot better for the platform.

Once you start getting close to $1,000 in budget, you have to re-evaluate your situation as the BC Racing coilovers are not a bad option for this price, though I never ran them on a Forester.
