I got a set of those from him for Christmas. He's a great seller! Install was a piece of cake. Adjusting the height is simple. The ride is definately stiffer. Around here where there are shit loads of potholes, you can feel every one like never before! Handling is vastly improved!! The car doesn't feel like it wants to roll over during a hard corner. My only suggestion is that they be dampening adjustable. Good buy
