gr8len, I replied to your PM.
From what I understand, the Eibachs that NeedsWings sells, etc. are supposed to work on any Crossfire. I believe the roadster bracing has nothing to do with the springs, you just remove them, install the springs, and reinstall the bracing.
I had the Eibachs on for a day or less. Drove ~10 miles or so and the wheels hit the insides of the wheelwells on every little bump.
Sure, it looked nice, but it was not worth the headache IMO. I would not recommend lowering a SRT6 Roadster.
