Question WRX, GS, adjustable struts?

Anyone running adjustable struts in G Stock (SoloII) on the WRX? If so, what are you running on how do you like them. Do you have to use the stock springs for G Stock or just height?

you can run any strut you want in GS but must retain the stock ride hieght and springs...

hell, you could get yourself a set of DMS 50mm coilovers if your so inclined. But they would have to be modified (read welded stock spring perches with stock springs at the stock ride height) to be legal in GS.

I hear that the KYB AGX is a good cheap choice. they are adjustable, and retain the stock spring perch mounts if I am not mistaken.

Actually, in the near future DMS will be producing a version of the DMS Gold with fixed stock type spring seats to be eligible for the stock classes.

Can anyone tell me how the rule reads? Do you have to use the stock spring? Can you change the rate? Or does the spring perch just have to be fixed, allowing you any diameter of spring?

Thanks.

The Stock class shock rule is actually kind of long, but basically an aftermarket shock must match the stock part's dimensions (free length, spring perch height, etc.). There are a few things that can be changed, however, including shock construction (twin tube vs monotube, adjustable vs. non-adjustable). Piston rod diameter can be changed.

Springs must be totally stock.

Thanks for the help.
I've been trying to find proof of someone actually running the KYB AGX on the WRX but I have so far been unsuccessful.

Default KYB AGX's on a WRX

I met Josh (that's his i-club name) He is running KYB's on his WRX wagon.

I forget the details, but I think he installed the KYG's from a legacy. you should ask him for details.

Default Koni adjustables

I believe Larry Fine, who has done quite well in several ProSolo events, is running Koni adjustable struts in his WRX. I seem to remember him saying that they are inserts for the RS, but that they fit the WRX strut tubes with a little fidgeting. I hear Koni inserts for Subaru are difficult to find though.

While I haven't run them in my RS, I really like the Konis in my VW. I'd prefer the Konis over the KYBs. AFAIK, the KYB's adjustment knob controls BOTH compression and rebound. In my experience, it is very rare that you actually need to mess with the compression. Assuming the compression is in the right ballpark, it is the rebound that really makes the difference and allows you to tune the ratio. The cover story in Sport Car (the SCCA magazine) a few months ago has a really good article by Danny Shields on the topic. I've ridden/driven/watched a number of RS's with KYBs, and it seems that the compression/rebound ratio is never quite right. When the rebound is where you want it, the damping is too stiff, and vice-versa. They're particularly difficult to tune on a rough course, where the end result seems to be bouncing at any setting.

The Konis only adjust the rebound, but if you're really hard-core you can have them modified to be independently double-adjustable.

DMS-USA: That's awesome news for Stockers! Will you also be making struts for the RS as well? At the moment, it looks like the RS has a good chance of being THE car in G-Stock next year. Some good struts from such a good company would be VERY welcome. Imagine, Subaru could be a successful choice in DS and GS!
