I understand Intrigue rear springs are good at stopping rear end squat when the car is loaded. I have heard the springs are progressive.My regal rear springs are very soft. I may replace my rear regal springs with these Intrigue springs. I did some research and found 4 part numbers for the Intrigue springs.


Q: What is the sport/good handling modelcalled inthe Intrigue and does anyone know where I can find the part number for these progressive springs? Is it just the GMPP upgrade springs or is it something different?
