Fitment I'm assuming the GT500 strut mounts are no longer needed for this part or is it still needed for 11-13 GT?

I have a 2012 Mustang V6 with the performance package. Will the upper strut mounts I have work fine or will I need to upgrade to the gt500 upper strut mounts. I see that its fine with the mustang gt's, but what about the V6's.

Clyde2012stang

  • You will not need to upgrade your strut mounts. Though, it is a good idea to get a set of the Ford Performance GT500 Style Strut Mount Upgrade (05-14 All), item # 50273, (http://www.americanmuscle.com/frpp-gt500-strutmount-0512.html). These Strut Mount will improve handling and performance while replacing your stock ones, which could potentially already have wear. It is a good idea to upgrade multiple suspension components when lowering a vehicle. We also recommend getting an alignment any time you change the suspension. This will help avoid any unnecessary wear on your tires.

    They aren't bad, but not great either.

    I purchased these only because they were on sale and I wanted to start wrenching on my car. Don't listen to the people saying they make a huge difference, because they don't. If you have a completely stock suspension and only get these along with the rear shocks you will not notice much of a difference. They did fit in place perfectly though, you will have to use the old bolts, nuts, upper spring seat assembly, etc. They don't squeak, and the ride is also very similar to stock not rough at all. While cornering they do make the car feel a little more firm and controllable but not enough to justify paying full price. So get them while they are cheap!

    Koni front struts and rear shocks

    I purchased both front struts and rear shocks for my gt to be used with Ford racing lowering springs for a 1.5 in drop and have to say the car feels much more planted and tight in the corners. Probably one of the better upgrades I've done to the car and would definitely recommended to people are are looking to lower their cars and want to do it right the first time

    Koni Str.t front struts 2009 GT/CS, handles good just squeaking and noisy

    Installed the new struts and took the car to get an alignment and on the drive home noticed a squeak coming from the front on both sides. Upon further inspection found the struts were squeaking. Contacted Koni received two new struts installed them today and one of the new ones is still squeaking. Emailed them again waiting for a reply to see where we go from here. Not to happy so far.

    Introducing Your Totally New Car!!!

    I purchased a set of these shocks and struts to finish off the array of suspension mods I was doing on my '14 GT to include SandR Performance lowering springs, JandM adjustable caster camber plates, Whiteline double adjustable rear lower control arms and relocation brackets, and a Whiteline adjustable panhard bar. I waited to get all of these pieces together because I wanted to do everything all in one shot, and I must say, my car is a completely different beast. Everyone knows that mustangs are a straight line rocket, but tended to suffer in the corners, and I was determined to change that. With the addition of these struts and shocks, my car now carves corners like it's on rails, and the ride is just as smooth, if not better than stock. I have no regrets whatsoever in purchasing this setup, and I highly recommend it to everyone I know with a 'stang.

    Good ride quality but terrible sound and company

    Installed these when I lowered my car along with SR springs, Koni shocks, and Bmr panhard bar. The car looks great and rides good but the only problem is the struts are making a terrible squeaking noise on every little bump. I took my car apart twice to check everything to make sure it was good and even took it to a shop to make sure it was the struts and they said it was. I called Koni and that was pretty much useless all they said was fill out a form online. A few guys on some forums are having the same problem and it took over a month for Koni to send them replacement struts... and they weren't even new. They didn't even try to make them look nice they just painted over the old koni sticker and put a new one on. I am embarrassed to drive my car now because of the way it sounds and its a 2014... I will be staying away from Koni and will never recommend them because this product and their customer service is terrible. I called the Koni guy again last week and he didn't answer so i left him a message with my name and number and my question and he never called back. The product does what you want but with an awful squeaking sound when you drive it.. if that's what you want then buy this product.

    Squeaking upon test drive

    Had a shop install a set Koni's with a new set of Eiabach Sportline lowering springs. Noticed a pretty annoying squeak during drive home. Brought the car back to the shop to have it checked out. Found the front struts squeaking during travel. Shop lubed all the components, still has a squeak. Hoping it's just because they're new, will drive for a little to see if they loosen up. If noise continues, I'll be sending them back.

    What a Difference These Struts Make!!

    I purchased these struts along with the shocks a couple of weeks ago and only recently got them installed at my local shop. My old shocks and struts were ready to go as my ride was extremely bouncy and the car rattled over every small crack and pothole. I kept the stock springs (for now). After the installation was done and drove away, I IMMEDIATELY could feel the difference in the ride! Ride is much better, feeling a little stiffer but just the right amount. This is my daily driver vehicle so I feel so much better in making this purchase. This is a mandatory upgrade for all mustangs! Thanks American Muscle!

    Good value for the money

    These struts are amazing, Koni makes one of the best in the industry, I have very satisfied with these, I also have the rear shocks and a bunch of other go fast suspension parts, like a a ford racing, lower control arms, springs, adjustable panhard bar & boss tower brace. The car is really dialed in, people tell me I should go road racing, maybe next year. Thanks American Muscle for offering great products for a great price!

    Koni Front Struts

    I had lowered my 2014 using all items from American Muscle using the Eibach Pro Spring Kit. I purchased Koni Rear Shocks first then a week later got the Koni Front Struts. I was not sure how much better it would be over the stock Struts & Stocks because I could not find the specs. from Ford on the stocks ones. After both front & rear were installed, all I can say is wow it really put the finishing touches on my suspension. The car was smooth before or I thought it was but now it's really smooth! Going over a bump no more worries at all. If you are going to lower your car this is a must in my opinion I had the struts installed by Firestone and added the camber bolts to them to do the wheel alignment , cost 120.00 for the Struts to install with Camber Bolts . Wheel Alignment n/c I have a life time contract for that. Plus the sale price you could not beat from Koni !!!!!

    Koni's as new shocks, same springs

    My wife's 2011 V6 convertible was in need of new shocks. It was pretty soft and bouncy at 49K. Decide to install Koni orange all around keeping the stock springs. Had Pep Boys install all 4 for $325 including alignment. They quoted me a price on Monroe's that was $30 more than the Koni's. Great shocks and struts. Car handles much better without being harsh. Was definitely a great choice for a daily driver!

    Outstanding

    Installed these Koni STR-Ts with K-springs all the way around the car and it was a huge improvement, great handling, but surprisingly the ride quality is excellent. The car doesn't feel harsh and bouncy like a lot of lowered cars do, some of that is because in was only a 1.5" drop, but it still handle and rides extremely well. I couldn't be happier with the performance of these shocks.

    Koni STR.T upgrade to V6 daily driver

    Installed Koni STR.T struts and shocks onto my '14 V6 daily driver ( std suspension). Installation was about 1.5-2 hours with the help of a friend with a lift in his shop ( 5-10 min for rears, ~1.5 hours for fronts of which much of that was spring compressor wrenching and searching for a dropped nut, fronts could be done in 30-40 min with a commercial spring compressor and air tools). Stock struts/shock were underdamped for even the stock springs from new. The Koni dampers eliminated the floaty feel the car had with the stock dampers and improved steering turn in and predictability when cornering on less than mirror smooth roads. The perception of brake dive is reduced as the pitch forward is not as sudden with the stiffer dampers. There is some (slight ) loss of ride comfort ( expected really ) due to the significantly higher damping rates the Koni shocks/struts have, and a slight increase in chassis noise over over sharper bumps, but the trade off of having a better planted, quicker responding car turns the V6 into a much sportier feeling car, even on the stock springs/sway bars. For anyone that is willing to give up a just little ride compliance for the significant improvement in suspension/body control the Koni's are worth the cost and work to install. I am very impressed with the improvement.

    Worthwhile upgrade

    Install wasn't bad at all. Definitely firmed up the ride but not harsh or overly aggressive. I have nothing else but the stock GT dampers to compare it to so it's better than those for sure!
