A lot of people say this brand of coilover is no good but my car is only road driven. I have had them for about four months now and they handle very well with no problems or noises. The install was easy enough and took about 5 hours for the whole car but I also did front control arms and sway bar end links. Look good and are definitely a lot lighter than the stock springs/strut and are a lot cheaper than if I was to buy one replacements. Changing the height is easy enough and gives you about stock height to 2 1/2 inches lower in the front, and maybe 1 inch higher to 2 inches lower in the rear.
