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

Echris

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

    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.

    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.

    For the enthusiast, no other choice...

    Since you are on this website then you obviously want something better than "stock." Like tires, shocks and struts have the ability to transform the ride and handling of your car. These are pieces that you want to buy the best you can afford; don't cut costs here. My 2006 Mustang GT has been my daily driver since I purchased it, so ride quality was paramount to me. After doing a good bit of research, I settled on the following combination: Steeda Sport lowering Springs, Steeda HD strut mounts, J&M aluminum adjustable panhard bar, and the heart of the suspension is the Koni Sports. On full soft, the difference verses stock is amazing. The car is so planted that it is completely transformed. Launching the car creates a birth if squat in the rear and the car just hooks and takes off. During braking the nose doesn't dive; car stays flat and just plain stops. During turns, especially on throttle turns, the rear stays plants, body roll is almost non-existent, and bumps do not kick out the rear end and unsettle the car like when it was stock. The ride is much stiffer but not at all unsettling or uncomfortable. It's perfect for a DD in my opinion. On full hard, the suspension feels like a race car and frankly, on horrible Pennsylvania roads, it's just too stiff. I'll save that setting for track days.

    Amazing cornering!

    At first had an issue with not receiving hardware. But AM was Very professional and fixed the issue without breaking a sweat! These shocks will improve your ride a ton vs stock especially if You are lowered. I'm running Eibach sportlines and my ride is no longer harsh or bouncy. Not it stays flat and planted while cornering. I'm running 0.75 turn up front and 0.5 turn adjustment settings out back.

    Nice improvement over stock!

    Installation was very straightforward on my 2014 GT 5.0 Auto. Did not present any major obstacles. Finished job in garage with jack-stands, basic tools and torque-wrench. Fit was excellent. Major improvement in how the car feels and drives. Not harsh at all, just a nice increase in ride firmness and damping. Quiet, with no change in NVH. After installing these on the rear, the Koni fronts are absolutely going on as well. Added an adjustable Panhard bar and HD panhard brace from here at American Muscle and couldn't be happier with the end results.

    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.

    The best upgrade

    This and the front konis are the best upgrade and improvement any mustang owner could make. Pair it with a set of SR Performance springs, J&M camber plates and a strut tower brace and you have yourself a road racer. This is a 150% improvement from stock in every way. Cornering grip and acceleration and hole shot are what impressed me the most... The car brakes more responsively. Handling the Texas whoops and bumps on the side roads are now non existent. It is a little stiffer but the overall improvement is amazing. This will be my first upgrade on any ride I get from now on. Holeshot traction improved by at least 75%....simply an excellent set up. Thanks American Muscle!

    fantastic ride

    I upgraded my Eibach Shocks and Struts with the Koni's and found a night and day difference. previously the slightest pothole or road imperfection caused a significant shake in the car. With these Koni's the lowered mustang rides better than before it was lowered. I had a shop install and they mentioned no issues with installation. Recommend to anyone considering lowering their mustang, or improving the ride over stock shocks.

    Ride quality much better than stock shocks.

    These adjustable shocks give you the choice of a stiffer shock for better handling, or a softer shock for better ride quality. I prefer keeping at the softer setting (about 270 degrees) for daily driving to get the best of both worlds. The ride is much quieter than the stock shocks, and the back tires stay planted on the road when taking corners. Overall a superior shock and very easy to adjust.

    The shocks the car should have come with...

    Love these shocks! They firm up the ride without being harsh or bouncy when left on low or in a low setting but really help with the feel of the car. You also have the option to turn up the shocks so they are far more stiff if you go road racing.

    This is the ultimate in handling upgrades! I have upgraded everything else but it wasn't until this piece of the investment that it all felt worth it. I highly recommend both American muscle and koni adjustable a for your ride.

    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 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.

    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

    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.

    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
