SCCA Solo II ruling

I've driven in a few autocrosses. I am looking for someone well-versed in SCCA Solo II rules for a specific part ruling.

I am trying to keep my car in the stock class, so I'm limited to what changes I can make to my car. I need new struts and only two different kinds are offered for my car. There's a basic, stock replacement set which would be better than what I have now (ancient, soft struts). But I want to move up to better struts.

The Koni Sport Cartridge (mfr part #86-2588SPORT) is listed in Tire Rack as being "Standard Adjustable." Would these take me out of the stock class or would they be legal?

Please help me! The Spring season is just about here!

That should be fine. So long as you don't modify the housing, stock replacement inserts are stock legal.
