Personally, I would never recommend to "cut springs." The Crossfire or any car for that matter when originally designed the ride, drive, and handling qualities were chosen specifically. Care and engineering goes into choosing the spring rates and damper rates. When buying after market springs to lower for increased performance, the new springs are professionally engineered and tested to match the vehicle.

When cutting springs one changes the rates.Hints, ride quality, breaking distance, and handling can be greatly diminished. This DIY can be unpredictable.

This is just my opinion, and I thought I would offer my 2cents. All I can say is do your research.

Correct and well done performance comes with a price tag.
