    5 Top Rated Questions

    For a street car, that maybe over time work itself to the occassional track or autocross day, how do the two KONI shocks compare, the SR Performance shock compare? My OEM ones have been making noise since 50K and I am looking to replace them now with the car at 77K miles. I am looking for something durable, improving ride handling, quieter.

    • We typically will recommend the KONI STR.T Rear Shock over the KONI Sport Adjustable Rear Shock, as they share the same valving, as the adjustable, but are locked into the settings that Koni has found most commonly used, making this ideal unless the car will need to adjust for different settings regularly, such as a street car that sees regular track use and must have different settings for the track and for street. We do recommend Koni over SR for most applications.

    When installing rear KONI yellows into a 2008 mustang, does one use the hardware supplied in the KONI box or must one re-use the hardware on the car?

    • When installing the KONI Sport Adjustable Rear Shock you can use the hardware provided by Koni.

    Now do you adjust these shocks? Can they be adjusted on the car?

    • The KONI Sport Adjustable Rear Shock have the ability to adjust the dampening of the shock. You are able to adjust the dampening when they are installed on the vehicle as well. There is a cap that goes on top the the shock, that is accessed inside the trunk, that you can turn clock wise or counter clock wise to adjust the dampening for a softer or stiffer ride.

    I have eibach sportline springs but don’t like the rough ride. Would these improve ride quality/softness but still have the good handling from the springs?

    • The KONI Sport Adjustable Rear Shock allows you to adjust the dampening you so can make the rear end as hard or soft as you desire. This will help eliminate that poor ride quality you are currently experiencing with the lowering springs on your factory shocks.

    Stock??? My car is completly stock with exception of flowmasters 10seriesmufflers. Will these shocks work with my stock suspension!

    • Yes these will work well with stock springs. Will help with brake dive and remove some of the floaty feeling in corner transitions.

      Must have for lowered car

      installed on an '05 GT with Eibach lowering springs. Springs were installed years ago when I was not as wise. Ride was very bouncing, especially on back country roads. Installed these shocks and set them as close to the middle adjustment as I could. World of difference. Easy install (90 minutes), and perfect fit.

      Koni sport shocks

      Great shock if you want the ability to make adjustments as you develop your car. They can also be adjusted to compensate additional weight (like luggage/golf clubs) for a road trip. I pared these with Boss 302 front struts/springs on my car. The result was a very balanced car

      A absolute must-have

      Extremely improved appearance and handling. On-ramps to the highway at 60-70 mph are comfortable and confident, the steering response is much more precise and immediate, and this is all on the medium setting. Definitely worth every penny. I absolutely recommend.

      A Requirement for SCCA Street Class Autocross

      Although these are not a cure-all for the handling deficiencies of the Mustang, I cannot describe the difference they make in weight transition situations. With the front set to full stiff, they are tame in slaloms and allow you to really push the grip limit to gain confidence in the car. On the street on full soft they ride better than stock, especially over speed-bumps.

      When it comes to making a adjusting to the shock it is not easy to do. Because there's no marking to tell you what level of adjustment you are at!!

      The koni yellows replaced my worn out Koni orange. To me it was a massive improvement. Love that I now have the option to adjust them when needed.

      What wheel hop?

      So I gashed my tire and when I went to replace the set of 4, I was told that I needed new shocks. I went all out. I purchased the front set of adjustable Koni struts, the same shocks, and (to really remedy the wheel hop) the adjustable lower control arms. Well, after the shocks and struts were installed, my mechanic urged me to give it a try. I did. Speed bumps never felt so good! Going over at tiny bump over 15 used to make those wheels hop incredibly, since new, but now, it's a very smooth ride. I would recommend these to anyone looking to have control of their comfort level and reduce wheel hop. I haven't even installed the control arms yet! Great product, totally worth every penny.

      Simple Install

      I consider myself a novice and I found this install to be extremely quick and easy! I couldn't be happier with the improvement in my ride quality. Takes less than 1 minute to go from soft "daily driving" feel, to a stiff Track Ready feel

      2014 Mustang GT track package - Koni Sport adj shocks

      First of all MAKE SURE TO REUSE FACTORY MOUNTING GROMMETS AND ISOLATOR!!! The mounting hardware provided with the Koni shocks will not work. You will get a knocking sound where the shocks mount to the body. I had to repurchase factory shocks to get the grommet as it is not sold without the shocks. :(, As far as ride quality, these shocks perform very well. Car stays flatter in the curves and launches harder with less squat.

      Smooth Ride

      Just had these bad boys installed and what a difference. Right now I have them set for the softest setting. (Haven't had much time to play with them) but what a difference from the stock ones. MUCH softer ride, no more clunking and rattling. I love them so much that I have just bought the matching struts. Highly recommended these shocks.

      Great shocks

      Great product, really gives a nice improvement over stock shocks, especially since they can be adjusted to road qualities or driving styles. The only qualm I have is the lack of detailed instructions enclosed on how to install and how to adjust them--however I did find some videos on how to install and how to adjust the newer model of both the adjustable front struts and the adjustable rear shocks. The install net wise only took about an hour and a half, the hardest part was getting the stock struts off using only a wrench and a clamp to keep the bolt from twisting.

      Good for the price, rougher, more stable and predictable

      Product looks very good quality, best part is you can adjust with a small cap/tool provided easily in less than 1 min. Package was received damaged which caused some cosmetic scratches but nothing to worry about. So I went ahead and installed them, took about 3-4 hrs without prior knowledge. Obviously the ride is rougher, but makes the ride more stable and predictable in corners. No more floating feel that comes with stock mustang gts or v6s. Also these shocks are a must if you lower your car with sportlines springs or similar, stock struts would not handle dramatic drop very well.

      What a Difference

      Took me and a couple of buddies about 3 hours to install. We also put in lowering springs and caster camber plates. Went to the track two days later and shaved 6 seconds off my previous lap time. Handles like I'm on rails and I was screaming all the way!!! Happy I got them on sale as well. Thanks AM

      Excellent Upgrade Over Stock

      I installed these shocks in about 2 hours, I was moving slowly as was cleaning and checking other suspensions components as well. The procedure I used to replace the stock worn out shocks with these superior Koni Sport Adjustables is as follows. Back your car up on some ramps just high enough to crawl under easily. I found I did not have to jack up car at all or remove the top rear sway bar endlinks. Loosen both bottom shock bolts, do not take out just yet. In your trunk area remove the top shock nuts, then go back and remove the bottom shock bolts, then pull shocks down and out. Install both Koni shocks by placing the top of the shocks into trunk area and put on the top shock nut hand tight. Now align the bottom of shocks with mounting holes and install same bolts you removed. Tighten bottom bolts to 85 ft/lbs and the top shock nuts to 30 ft/lbs. I then adjusted the shocks from the top using the tool supplied. I set mine at full firm as I will be installing the front Koni Struts to match, then adjust as needed. These shocks on full firm make the car handle much better and on full launch from a dead stop, the slight wheel hop I had left was totally gone, car feels like a beast! I do highly recommend these shocks you have so much adjustability for hard launching, cornering, even braking improves. Another quality part from American Muscle I am glad to have put on.
