It's not a big difference but, it's definately one that is noticed; in preformance and image. I have nearly no experience working on cars, so I thought the installation would be very difficult; however when I purchased this kit and read the instructions I had no problems installing it, all by myself. It did take my longer than the recommended time
. As far as the proformance of the kit; I would say "outstanding". I've taking my car to it's limits and haven't had a problem out of the lift kit. As it's very well built. I even have 1 1/2" hub extentions and 3-X9 M/T tires. I've put around 15,000 miles on it, since the tires and haven't seen any wearing issues. All around, a great product.
