do they include hardware? do they include hardware ? and also would i keep my stock ride quality with this shocks?

Luis281080

  • They include mounting hardware. We replaced the stock springs with a set of Sportline Eibach lowering springs during the shock install, so we really can't make a fair comparison. I think you'll be happy with the Koni's.

Are these softer than stock?

Joe

  • No, they are stiffer than stock thus keeping the rear end tighter and preventing rear end bounce.

Will these stop the bounciness caused by lowering springs. I am lowered 2 inches in the back. I am on a budget so i cant do the adjustable ones now.

piezan76

  • The KONI STR.T Rear Shock will help reduce the bounce that is created from the installation of lowering springs. Depending on the severity of the bounce caused by the specific spring, results will vary.

    Great Value

    Installed these with the Struts and SR Performance springs. It all comes together nicely. The Springs are fairly firm and this shock feels a tad soft for them, but it's still a great setup. No doubt, if you can afford the Yellows, go for it, but if you're on a budget like me, these are great.

    Great Shocks for the Price!

    These are great shocks. Put them on the rear of my 2010 Mustang V6 convertible and they perform wonderful. I had previously had Monroe Sensatrack shocks on the rear and there is just no comparison, these are so much better. Highly recommend.

    Some people have said that these shocks are simply a replacement for the stock shocks and they are not. They are stiffer than stock and provide more control on the body as the car goes over bumps, less bounce up and down. While this is a tad more jarring, it's nothing that someone who is familiar with driving a performance car can't live with, as it's not much worse than stock. The orange color is a nice change of pace over the stock black as well. Overall I recommend them as an improvement-but not a dramatic one-over stock.

    Great shocks

    I bought the shocks and struts and had them installed my stock Ford shocks were well worn out and made for a very hash ride at 80 k miles . Originally I was going to get the adjustable Koni's but since I don't track race there was no point in it . I was looking for a smooth ride for my mustang and they delivered soft yet firm and the ajustables would have not provided a better ride at full soft setting , so if you don't track race on weekends and just need a good all around street shock hence the name Koni STR's then you can't go wrong.

    Very good results

    I have Ford 1" lowering springs and had KYB's installed, The Koni's are a huge improvement in ride and keeps the car on the road better. they are a little soft for high end performance but a good balance for a DD. Be worned though, the Koni's do nopt come with mounting hardware - you are expected to reuse the old. With the KYB's the hardware did not fit. Koni stepped up and sent the required hardware though no charge - so thank you Koni.

    Koni STR Rear shocks

    Installed these on my used '06 GT. Installation was a breeze. It took about an hour with basic hand tools and jack. I just wish the manufacture supplied hardware. I installed a set of SR springs a couple of months ago and I was trying to save some cash and decided to run the shocks that were on the car, they looked fairly new. That didn't work, the rear was soft and bottomed out. I read reviews on these and bought a set. The ride and handling are 100 percent better. The car is riding on rails. Lesson learned. Thank you AM for excellent service.

    Improvement over stock

    Installed a set of Koni non adjustables front and rear along with a set of Eibach sportline lowering springs. First couple of days had a bad squeak from front struts. After a couple of days squeak went away, the ride is firm but acceptable. Definitely improved the overall appearance and performance of the car.

    Lowered 08 GT/CS

    Awesome Product! My GT/CS has the HR Super Sport springs so it has been lowered quite a bit. I have to cut the bump stops down so it was not sitting on them. the problem was the stock shocks were very easy to bottom out hitting bumps and in particular badly made bridges that had a lip on and off. I put these on the back of the car and WOW did it change the ride. Much tighter but smoother over rougher roads. My old shocks were not leaking or have any visible signs of being bad but they sure don't compare to these Koni shocks. One of the best investments so far. I marked it took an afternoon to change but that is kind of misleading because I also change the brakes at the same time so just the shocks would have been considerably less time, maybe an hour.

    Install was extremely easy. However, I haven't felt any noticeable differences in performance and ride quality. Would recommend buying these as a replacement if the oem equipment failed.

    Koni STR shocks

    Perfect replacement for my old 65k mile shocks. Bolted right into place without issue and added the Ford Racing springs, and J&M Lower Control Arms while I had the rear apart. This combo really tightened up the rear end, keeps the wheels on the ground, and gave me the exact drop I was looking for. Highly recommend this product!

    I didn't want to fork over for Yellows at the time but these are great for the money. Very controlled ride without killing your spine. Install was very easy. I put these on my 2011 with GT500front mounts and STR.T's all the way around.

    Great!

    My package came in less than 24 hours after placing my order. Unbelievable. These were very easy to install and there is a noticeable difference in ride quality over stock. My stock shocks were leaking so its like night and day now. Hard to say if its just because I was used to the broken ones are these are just THAT good however. Not sure why the "install difficulty" is "Hard". That might deter potential buyers who want to do the install themselves. A teenager with a jack, socket wrench, and common sense could do this install in a couple of hours at most.
