Review & Installation Video

Review & Install Video

Hey, everyone. I'm Justin with And I'm gonna be taking a closer look at a very affordable coil-over kit from SR Performance fitting your '79 to '04 solid rear axle Mustang. These coil-overs from SR will be an alternative to those other big brand name products on the market but won't come with that big brand name price tag. Now, whether it's suspension components like these coil-overs here or other modifications, SR Performance will perform without breaking the bank. I'm sure a lot of you guys watching this video are already familiar with what a set of aftermarket coil-overs can do, but if not, here's what you need to know. A set of coil-overs like the SR option here basically combines two vital parts of your Mustang's suspension, the springs and dampers, into one easy to install, relatively affordable package that most importantly gives you the ability to address your rod height whenever you want. Now, this is something that isn't exactly possible with a traditional set of springs, shocks, and struts. Besides that height adjustability, these coil-overs from SR Performance will no doubt improve your ride quality and handling performance by replacing the old and more than likely worn out stuff in your Fox body or SM.95. The coil-over kit itself includes both the coil-overs for the front setup here, already preassembled, spring and strut, basically meaning you won't have to mess with any spring compressors. Just bolt on and go. In addition to the fronts, of course you will receive the rear, which is a brand new shock setup along with the springs and adjustable perch here. Now, this setup will not include brand new caster camber plates, but it is something we highly recommend here at to really dial in that optimal alignment settings, especially if you plan on going low, which these coil-overs will certainly allow. So if you are interested in checking those out, you can always do so on the product page or by clicking on the link below. Speaking of low, these coil-overs from SR Performance will allow you drop your Fox body or SM.95 up to three inches, which judging by some of the customer submitted images here on the site, is essentially enough to allow you to slam the car to the ground. So be sure to check out some of those images if you get the chance. The process of lowering your ride with these coil-overs is pretty simple. You're gonna use these two spanner wrenches included with the kit to adjust the collars on either the rear or front setups. Basically, take your time and make sure to measure so you get everything nice and equal. Getting to that install one more time, again, since you do not need a spring compressor with these coil-overs here, the install is very straightforward, and I even recommend my novice mechanics out there to give this one a shot. Now it should take you roughly four hours or so from start to finish, so if it does take you a little longer, don't get discouraged. But either way, if you would like to talk to a Mustang expert a little bit more about the coil-overs themselves or about the actual install, feel free to reach out anytime. So if you're looking to replace the 10 to 20 plus year old suspension in your Fox body or SM.95 and you'd like to have the ability to adjust the ride height to your own personal preference, then you won't be disappointed when checking out the very affordable options from SR Performance which you can find right here at

Performance Handling. Improve your Mustangs handling and give it a suspension worthy of a true track car with an SR Performance V1 Height Adjustable Coilover Kit.

Recommended Upgrade.

Is this package daily driver friendly? My suspension is currently stock, but wearing out. I'd like better handling but don't want a ride that is much harder than stock. How would these work as a daily driver modification? Also, I noticed that the front spring rates are less than half as stiff as any other springs AM offers. What is the reasoning for such low front spring rates?


  • Yes. It will have excellent ride quality and even better handling characteristics. I personally love the kit on my DD and would recommend it to anyone who drives their car to work everyday.

I ordered the coil over kit and then the camber plates. I am having trouble putting the front coil overs on. I am unable to get the bolt on top to secure them. There is still about half an inch left before it even clears. Is there any tips on how to get them on?


  • With the SR Performance V1 Height Adjustable Coilover Kit, it could be a little difficult to install, if the perches are adjusted to a high position. We would recommend threading the perch to the lowest setting, and install the coilovers and once they are in, you may then adjust those perches to achieve desired ride height.


Helpful (1)

should you still replace your front and rear spring isolators? do they even use or need isolators..


  • They are no longer needed after installing the coil overs. The rears come with new spacers to take the place of the stock rubber or aftermarket polyurethane isolators and the front spring pocket will be empty. Hope this helps!

Will the this Coil-Over Kit work with a UPR K-Member?


  • Yes, this will work with any K member that utilizes stock front control arms.

I know this sounds weird but I want to lift my mustang about 3 inches. I don't want to go the cheap route and get spring spacers though. I know that coil overs allow you to lower your cars ride height but would I be able to increase the ride height with these as well?


  • Unfortunately the SR Performance V1 Height Adjustable Coilover Kit is only able to lower the car, cannot lift with these coilovers.

Are the front shocks gas filled? The bracket on the bottom of mine has broken and I need to know if it can be welded or what.


  • The SR Performance V1 Height Adjustable Coilover Kit should not be welded, as this can compromise the integrity of the shock body or strut body, causing serious safety concerns.

    SR coilovers for my 86 gt

    I am loving my choice of suspension! These are the only suspension mod I have done to my car so far. I've been driving on the SR performance coilovers for about 3 days now and They are a big improvement over the factory set up! The ride is just stiff enough but not to stiff we're it makes it uncomfortable. My car feels stable around turns at speed and doesn't squat on take off or nose drive with hard braking. The installation was easy and took a full day for me with basic hand tools and the internet.

    Extremely disappointed

    Complete waste of time and money. I bought them to have some choice in the ride height. There is no choice, car scrapes everywhere unless adjusted to the highest setting. They pop, klunk, and rattle when turning and going over bumps and generally feel unsafe. I wish I could return them. Out almost $1000 when you count the required caster/camber plates.

    Amazing set up for price!!! Huge improvement!

    I bought this set up last winter and finally got to install when I finished my resto. Wow! What a difference from the KYB/BBK set up my car came with. This kit is perfect for a daily driver, not too stiff and not too soft, but great when you take the car to the track. Took me 2 hrs to install, material quality seemed to be good and everything installed with ease.

    SR performance Coil overs

    I ordered these about a year ago, never installed them and I ordered the camber caster plates with them but unfortunately I got the wrong plates. I haven't had a chance to drive with them yet I am very excited to see the stance on my mustang after. Great product especially for the price.

    DON'T BUY Coilovers Snap!

    Don't buy these they make the car look great but after 4 months the right front snapped. American Muscle customer service is great and sent me a whole new coil-over, but in 3 weeks the front left snapped as well.

    Get what you pay for

    I bought these coilovers with the camber plates the difference you can notice right away you. But the build quality is bad from my experience. I went through some railroad tracks(very bumpy) not even hard going around 40 I heard a metal snap. Didn't think about then as it turned one of the coilovers snapped I had to get my mustang towed. Went to stock suspension. I had to buy camber plates and the camber still won't align right. Safe to say I will buy these coilovers or any SR product ever.

    Not as adjustable as I would have liked

    I bought these coilovers for an adjustable suspension so I could easily transition between street and racing. These made my car extremely LOW and will not adjust much higher. They are advertised as a 1-3 inch range, but I got more like 2.5-3 inches, so a range of maybe half an inch.That means the car is almost un-driveable on the street even when adjusted to the highest setting. I even bottom out pulling into my garage going over a small hump. As to racing performance, they are certainly better than my stock shocks that I replaced, but not as smooth and tight as I would have expected. Love Amercan Muscle and always have a good experience with them, but I would not recommend this product.

    SR Coil-Over Review

    I ordered this kit for my 2003 GT that I daily drive. Everything you need for the install comes with the kit except for the caster camber plates which I highly recommend getting along with it. Installing it all in a family friend's garage took just over 5 hours, and that's with some set backs of rusted bolts and what not. After installation and driving it around for a little while there is some rubbing noises under the hood that I haven't figured out what it is yet and may just be in my specific situation. Hitting bumps and anything else on the road sounds horrible from inside the car since the suspension is a lot stiffer than stock, but it normal with a kit like this. Overall, with the relatively simple install and adjustability of this kit, I highly recommend it for any SN95 owners.

    went out in a year and 4 months -__-

    Product was great for the time it lasted, made the car have a great stance, but unfortunately the driver side strut metal piece where the nut goes snapped on me early March of 2016. Had it installed by Wheel Works and everything has worked well since then. Pretty upset it gave out on me unexpectedly and definitely would not buy again.

    I wasnt sure about going with sr performance as their products are normally cheaper and arent as good but ive had these for about a year and they still work great and havent blown as is common for any coilover kit. This kit allows youre car to be ridiculously low or have an aggressive stance and improve corning. Though with that you get a rougher ride.

    These were pretty good for the money. You definitely get what you pay for in quality. It took me quite a while to install these in my car with the caster camber plates being there were no instructions. I think the rear shocks in this kit aren't much better than stock. But the front is a little bit better.

    Love the new look!

    Really simple install but all of the amazingly tight bolts and springs will slow you down. Love the adjustability, the new look, and the inproved handling. If you are looking to slam your car- my rear height adjustment is maxed out and there is still a 1.5inch wheel gap and the front can still go lower by a lot. But im sure it depends on what wheels you have.
