The 46mm shocks are sturdier, have less travel, and their spring rate is the same as the hardest option for the singles at S111. If you're not building a dedicated track car, and don't have aero, I'd go with the nitron singles with the soft springs. That's exactly what I have in my car, and it works great with slicks and no aero. It's also comfy on the street. I don't know about auto-X though, as I don't do that. (keep in mind that the Soft springs are much harder than LSS and more than double the stock suspension).

Save yourself $600

I totally agree. I have the Nitron singles also.
