Have not personally felt their ride on the Camaro but the members that have posted about them say they are quite stiff. When you stop and think about it, they have to be considerably stiffer since they are quite close to the bump stops. Also, you might have problems getting a good alignment on the rear unless you buy the aftermarket alignment parts. The OEM adjustment is hit or miss with adjusting that far out. If this is your DD and ride quality is important to you, you might want to look elsewhere. As far as quality, I think they are close to Eibach. Meaing, they are more of a budget spring that doesn't have the quality of Pfadt or Pedders. Pfadt makes a 1.25in drop spring that looks great on the Camaro and the company is second to none. They also have fantastic customer service so you know you're 100% covered if you run into any problems.
