I am about to purchase Global West front and rear springs. I have a few questions that I hope some members will be able to help me with.

1. What is the difference between the Performance Street and Semi Comp springs?
2. What are the spring rates of the front and rear springs for the Performance Street and Semi Comp springs?
3. I know these springs will lower my car about 1 - 1.5 inches. Does anyone have clearance problems after lowering their vehicle this much? How often does the car scrape? - entering driveways, speed bumps, etc...
4. Anyone have pictures of their car with this setup?

Thanks for the all the help.
