will these springs be ALL i need for my 2013 v6 performance package? i was wondering if i needed anything else to put these on with my 13 performance package?


  • William, you should also install an adjustable panhard bar (around $120) because when the car is lowered it changes the geometry of the suspension and in the rear it causes the axle to shift to the driver's side. The adjustable panhard bar allows you to 'center' the rear end (it's not as hard as it sounds). Now for the front. Eibach sells camber adjustable bolts (around $25) for your car that should be installed as well. Our cars do not come with a camber adjustment from the factory, so to get your alignment right you should install these to give the alignment shop (yes, another $80) the adjustment they need to correct the camber change that will occur. You don't HAVE to do any of these things, but if you want it done RIGHT and not have any premature wear issues, you SHOULD do them. p.s. be careful removing the front springs from the struts. The strut plates are pretty cheap and the ball bearings will fall out from between the plates if your not careful. Hope it helps!

Can you wait on C/C plates? Should caster camber plates be installed same time as springs or can you wait to install depending on necessity


  • You will want to get your wheels aligned after the install. Depending on the drop, the alignment shop may or may not be able to get your alignment back on spec. If you need the plates, the longer you wait, the more wear you're going to have on your tires.

    Good quality springs, lowered the perfect amount.

    I put these on my husbands 2013 5.0, and must say I am very happy with the quality of these springs from Eibach. However, there was no instructions in the box, American Muscle has a great PDF write up here on the site, but I feel there needs to be a hardcopy put in the box with the springs. I also do not like that I purchased these for $30 more during the month of December (an Xmas present) and now (January 4), they are only $230. This is a reflection on American Muscle, and not Eibach. These are worth their money, pretty easy to put on; just take your time and follow the instructions here on the site step by step and you'll have it lowered in no time!

    Looks Great, Handles Even Better

    I spent a lot of time researching suspensions systems, and I finally settled on the Eibach Sportlines. I realize they are a little more "extreme" than some of the others, but they make the car look and handle great. Installation was pretty straightforward. It took me most of a day because I had to run out and rent a spring compressor. I also took advantage of having the car on jackstands to replace the panhard bar and sway bars. One word of advice: make sure you have a jack that is low enough to clear the car after the front end springs are installed. I had to buy a new jack because my old one was too tall to pull out after the new springs were installed.

    I put these on my 2011 GT with the Brembo package and it handled great before but now its just silly fun in the corners, not to mention that it looks really aggressive. There is a positive increase in confidence through the corners, well worth the money. I have the stock struts/shocks and the ride quality is firm but its not "jar your bones" firm. Put it this way, my mother likes how it rides, so most people shouldnt have a problem with ride quality. i love how the car sits nice and level!!

    eibach sportline

    awesome suspension set up for a daily driven car that hits the track on the weekends. Fits perfectly and smooth when installing, comes with lower bump stops for the rear end which helps a lot not to be so bouncy. The car lowered exactly what they claim, a very aggressive balanced appearance from the front and rear. It is exactly what you can expect from Eibach :)

    Great Springs

    Installed springs on a 2013 GT spring compressor needed.....took 3hrs. Would consider mech skills above average. Drop is perfect....glad I went with the sport line. Have not bottomed out or scraped the car in about 200 miles of driving. Also installed an adjustable pan hard bar....very strait forward install. Handling is night to day goes around corners like a sports car should. Do no hesitate to buy!

    Corners on rails

    The Sportline springs have not only given my Mustang the look but have made an amazing difference to the cornering ability; no perceptible roll, as well as minimal pitch under braking and acceleration. Now I can make full use of my 93 Octane hybrid Bama tune! It's like she's on rails going around corners; truly! Ground clearance is now a front and back 4.3" (clearance to splitter and convertible bracing). Need to have a real low hydraulic jack to get under the car now though. Ride is firmer and you certainly feel the road surface more, even with stock 17" tires. The rear bump stops engage on bumpy country lanes at speed and make a solid thud - got to slow down compared with stock! However, the compromise for the cornering is well worth it. I have no squeaks and added the Eibach camber adjustment bolts I used a spring compressor to avoid removing the convertible bracing at the rear. The new springs will fit without the need for a compressor. Watch out for the ball bearings falling out of the top of the front strut when compressing the spring. Do it on a table to not lose them. I cleaned mine, regreased and reassembled. If you want amazing handling on corners, less rear axle hop and a stunning look, get these Sportline lowering springs!

    Perfect ride!!

    Great springs wish the car came with these from the factory because before the car looked like it was going off road and now it's perfect. Very simple to install and it on a lift with all hand tools. Took about 2 hours to do everything including the J&M rear panhardbar. Car rides great not to bouncy, no nose dive with hard braking, and handles great. Should have made this my first mod. Note I only have 7200 miles on my car and a lot of people say to replace the upper strut mounts but re used mine and no problems here, overall definately love the way my car looks and drives now.

    The Stang looks awesome with the Eibach springs. Rides a little rough and bottoms out now and then, but I have had many lowered cars and trucks so I am use to it. I'm hoping when I put 20's on it doesn't get much harsher. Installed in about 2 hours on a lift.

    The most compliments in one weekend than the whole year I've owned it.

    I didn't think it would make much of a difference, boy was I wrong! It looks great and handles better than before. I wish I would have done it sooner. I does take some getting used to due to the fact that it's lower and scrapes when going over some speed bumps but well worth it.

    Awesome set of springs

    Expect little to no brake dive after installing this great set of springs. Also no staring at the sky when you give it a little gas. The car still maintains good ride quality and I am not getting any front end "clunk" at all over bumps/rough roads (re used oem mounts). Also about the easiest spring install ever...about an hour with a lift and a buddy.

    Impressive change to the car

    My '12 Perf Pkg handled well off the lot but the sky high stance bothered me, as did the initial leaning on turn-in. I bought these springs after a lot of reading of reviews and I am glad I did. Easy to install (buy yourself a proper strut spring compressor - about $60) and did not take long. The stance is now perfect and the turn in is crisp. I read that they were rough but even on bad pavement they aren't annoying. I am still running the factory 204A struts and shocks and they control the stiffer springs well. I did get an alignment to fix the toe from lowering but the camber was still within spec and I would recommend getting both an adj panhard rod - I went with the JandM - as well as new strut mounts as mine came apart when I took them off the strut. Highly recommend these springs - my car changes direction like a shark now.

    Great ride

    The ride is absolutely amazing now with the sportlines no more body roll, it handles great. My brother installed them for me as a favor and did fenomenal job. During acceleration i noticed that it doesn't feel like the car is shooting to the sky anymore. It actually plants to the ground and accelerates better. More power to the ground. I recommend Sportline to everyone. The look now is amazing.

    Sitting Pretty

    After measuring wheel gap and seeing my splitter sit 7 inches off the ground, I decided I needed an aggressive drop. Sportlines had the right numbers. Splitter sits just over 4 inches high and my wheel gap almost disappeared. Of course the ride became more solid (feel more of the road) but that's what I like. Might not be to my wife's liking but she hardly rides in my car and doesn't drive it. Love my stance and my staggered wheels fit just fine. Only barely rubbed once when I took a roundabout turn aggressively fast to test my limits. And so far I have not bottomed out on anything.

    Time to drop it.

    I was a little concerned about lowering my GT. And keep going back and forth trying to choose a spring. I finally went with Eibacjph because of their reputation and customer reviews. The sportline springs give my car a nice appearance and stance. To me the ride quality was not sacrificed. Yes it's firmer but more responsive and agile. I'm glad I didn't go with the Eibach Pro kit because it would not have lowered my car enough. In addition to the sport line springs I installed maximum Motorsports camber plates and J&M panhard bar. Because of the amount the drop I figured it was best to make sure the rear axel was properly aligned and that I would burn through my front tires either. Overall I am very pleased with the Eibach Sportline springs. I would definitely recommend them to anyone looking for better performance and trying to get rid of the huge wheel gap

    Great handling kit

    The install took a little bit longer than it should have because, as mentioned in another review, you don't want to drop the upper strut mount. You'll never find all the bearings and your local Ford dealer may not have them in stock. The instructions say to remove the additional bracing on convertibles to install the rear springs but you can use a compressor to remove the stock springs and then just slip the new ones in. The handling is so much better now but even though I don't notice it much my wife says it's a bit harsh on the bumps. After I did the front springs I took is for a ride and since like a street rod stance it looked really good but there was still a large gap between the rear tires and the lip of the fenders so I finished the install with the rear springs. The kit lowers the car exactly what is advertised but the rear is a bit too low for my liking so I wish the rear was only a 1" drop. A 1/2" spacer would be nice but so far I haven't been able to find anyone who makes one.

    great appearance and handling improvement

    Sportline springs are a great way to improve handling and appearance of your mustang. Ride quality is not compromised and the progressive spring is great for street or daily driver use. I live in a city with a lot of potholes and bumpy roads and the springs handle the bumps fine. Beware of steep driveways or speed bumps as it is easy to scrape the front spliter. Also beware of high curbs as you will not be able to open the door if parked too close. Eibach springs improve handling confidence and greatly reduce wheel hop during launch and acceleration. Also these springs help reduce body roll and brake dive. Installation took about 4 hours with 2 people and installation guide was spot on. Hardest part was getting the old bump stops out and new ones in. Also highly recommend an impact gun if you are going to attempt yourself. Overall good product.
