Denny is great to work with and almost always answers when you call or he'll get back to you very quickly. I really enjoyed just shooting the bull and bouncing ideas off of him. All around great guy and there to help. And the best thing of all, my car actually feels safe to drive on the streets now after installing his kit. I can shut the car down quick and it stops straight as an arrow. It wasn't at all like that with the factory setup.
