I am intrested in buying Eiabach sportline springs because I want to drop my ride 2 inches. But I found out that the convertable V8 5.0 or 4.6 only offer the pro kit which barely drops it 1.5 inches. Please help and let me know before I make a mistake and purchase the pro kit. Or if any one knows another make that will give me the 2 inch drop Im looking for.
