FOR THE DRIVING ENTHUSIAST
Built with daily driven sports cars in mind, our Pro-ST shock absorbers are shorter than factory, lowering the vehicle approximately 3-inches while still retaining full shock travel. This, coupled with the 12-way damping adjustability and stiffer springs, allows you to adjust to the perfect setting for the driving environment.
52MM MONO-TUBE SHOCK BODIES
Large 52mm seamless carbon steel mono-tube shock bodies provide strength and provide room for a larger hydraulic piston and valves, more shock oil, and an enlarged nitrogen chamber. All of these upgrades add up to huge jumps in compression and rebound response, vastly improved handling characteristics, and extreme durability even in the harshest of conditions.
INDEPENDENT HEIGHT ADJUSTMENT
Externally, the shock bodies are threaded along their length to fit spring preload adjustment collars and the internally threaded lower shock mount and collar. This allows for independent changes in ride height and spring preload, giving the ability to tune each corner's weight to achieve optimal 4-wheel corner balance without sacrificing ride quality. Additionally, the shock body and threads are protected from the elements with gold-colored zinc electroplating and the lower shock mount is powder coated.
PERFORMANCE COMFORT COILS
After rigorous testing, we chose to fit linear rate springs instead of progressive. Featuring spring rates of 10kg/mm up front and 8kg/mm in the rear, the linear spring offers more consistency under all different measures of weight loading while cornering and hitting bumps. This offers the most predictable vehicle feedback in all driving situations. Each 2.5-inch spring is made from the highest quality AE9254V Chrome Vanadium forged specifically to work with our oil-nitrogen filled strut to provide the greatest possible balance of street and track performance.
STREET, TRACK AND EVERYTHING BETWEEN
Each Pro-ST coilover features a machined, knurled knob at the top of the shock shaft. The 12-way adjustment variation gives you complete control over the ride quality and handling of your vehicle. This allows adjustment for street or track use and everything in between in a matter of seconds, without removing a wheel.
TOP LEVEL STRENGTH
A suspension system is only as strong as its mount to the chassis, so all Pro-ST kits include aluminum, CNC machined, anodized top mounts for maximum strength and protection from the elements. High quality polyurethane bushings are included to keep precise handling and feedback while retaining a cushier feel for the street. Additionally, a padded spring seat at the top and nylon thrust washers at the bottom of each spring reduces friction to eliminate noises from spring bind commonly found in many coilover systems.

I got the skunk 2 14-15civic si pro st coilovers. I really like them along I was able to raise the rear of the car a little and with my upper adjustable rear camber arms that I've had for longer I can now be a part of that stance life. In all seriousness I installed them at work and it was pretty straight forward. Definitely need measuring tape or a tool to measure. But once it's all the way you want it and get the alignment done with the specs you want and it's pretty good I raised the rear end and lowered the front and I'm happy with it. I tested the stiff and soft settings on the top of the coil over and rear shocks. I started with the stiffest setting and that is very bouncy lol. I lowered it to 7 in the front and 8 clicks in the rear and it is much smoother now. Im very happy with my purchase. The main reason I did this was because I have after market wheels and my tires hit the fenders in the rear and I didn't want to have a blow out so to have a little stiffer shocks and raise the rear a little helped very much now over the bumps I used to hit I no longer have that issue. I'm sure if your going to slam the car to the ground by lowering it just be careful full with drive ways and bumps and tire sizes but a very awesome product. I recommend doing it on a lift. But it can be done with Jack's and jack stands just more time consuming. I did it with a lift at work a d it was very easy to do. Thank you K series parts.
