I just got done installing these over the weekend and it was a very straight forward process. Very simple to replace instruction are clear and easy to follow. I left the set up complete as it came out of the box so I could see how my ride would change. Spring rate on these are 8k front and 6k rear, drop rate is 1.1" drop on the front and a 1.3" drop on the rear. It does have a 30 adjustable damper setting that is set 16 clicks to the softer side. If you can get the car up on 4 jack stands to make the job of putting the car back on the ground easier. All hardware is provided in the box and did not have to modify what I was provided or the car at all. After I got the car back on the ground I did measure and the front does sit a little lower then the rear does so I will need to adjust that. I took the car out for a 30 mile drive after the install and hit everything I could possibly hit. I went through a road under construction, potholes, railroad tracks, and normal bumps in the road. I did not change how I drove when i came up to these hazards as I wanted to see how it would perform compared to the stock set up. I was pleasantly surprised at the ride quality. It felt as good as stock in terms of smoothness. There was no harshness to my ride. The car did not bottom out and there was no rubbing. Next I took the car out on a twisty and had a lot of fun. The car was able to go around the corners much faster then before. I fell stuck to the road and just with this mod I did notice less body roll. This is the only suspension mod I have on the car right now. Only tip i have is make sure you read all of the instructions before starting the steps so you know in which order to remove the rear suspension bolts.

Overall I give this set up a 10/10

Since some time has passed, how do they feel and have you had any problems? My only question or concern about these is why they don't have adjustable camber plates on the fronts.
