Even though it was an easy install, annoyed that there were no instructions on how to do anything. Had to watch Youtube clips on how to remove the bumper and install the diffuser, but it was still frustrating that there are no instructions on how to wire the 3rd brake light and there's little to no videos or sites with wiring diagrams/directions. The product is amazing and it gives the rear end of the A Spec a lot more of an aggressive look, which is what I'm going for with my build. High quality, good design, and easy install.
Fairly easy to install. Best to watch some youtube videos first. Replaces front struts (fully adjustable) and front control arms (fully adjustable). Dampers can be adjusted with a simple knob where the struts bolt near the engine bay. Rear shocks (fully adjustable) were easily installed. Adjusting the rear shock dampers requires removing the wheels. Adjust the height on the front or rear suspension requires fully removing the wheels, but it should not be hard with the vehicle on a lift or jack stands. My only complaint was not including rubber padding for the rear coil-over springs. The stock ones have to be modified by cutting the outer rubber. Since the 2017 Civic SI has computer adjustable dampers I recommend purchasing the ADS blocker kit to avoid throwing error codes into the car's computer. They plug in and can be zip tied into place. I installed them and received no error codes. This suspension is natural more stiff than the stock version, but offers a better ride experience for anyone who is going to be doing higher performance driving.
A great bang for the buck upgrade!
It wasn't the easiest install for me without removeing the turbo but it keeps the temps down and I was able to reuse the factory heat shield but it would look so much better leaveing it off. Once the down pipe is installed with the lave blanket I will proubably do away with the factory heat shields.
