Product Description

Eibach Sportline Coil Spring Set for 2011, 2012, 2013 and 2014 V6 and GT Mustangs and 2012-2013 Boss 302 Mustangs.

If you’re looking for high-performance lowering springs for your Mustang, Eibach Sportline coil springs are your solution! Eibach springs are designed to lower your ‘Stang and improve your handling while giving your whole ride that just-above-the-surface glide. If you own a V6, GT or Boss 302 Mustang, you can easily set up your ride for responsive handling, even around sharp turns. When you want the best in suspension, get Eibach Sportline coil springs!

Eibach Sportline: Sharp, Predictable and Exciting Handling

Eibach Sportline is the extreme-performance spring set created for the extreme enthusiast - the one who craves a race-car attitude for maximum street performance - with the lowest possible drop, but with the exceptional ride quality you expect from Eibach.

Eibach made these springs to achieve outstanding steering and driving comfort on every compatible Mustang, and they work perfectly. Even if the springs only lower your ride half an inch, you’re lowering a lot of weight closer to the ground. Every little bit counts, and you’ll notice that when you’re hugging the curves of your favorite back road or gunnin’ it down the track.

Eibach’s masterfully-engineered springs are made with the perfect stiffness to support your Mustang while still allowing the suspension to keep your pony car’s body safely above the road’s surface. They’re also just the right size to let you turn on a dime without turning so hard that you throw your passengers around the cab of your car. All in all, these springs deliver the performance results you want while keeping you, your passengers, and your ‘Stang safe when you’re taking sharp turns.

Engineered with the same care as Pro-Kit springs, Eibach Sportline springs achieve legendary handling by aggressively lowering your car's center of gravity, using Eibach's precision engineered progressive spring rates. By lowering the ride height of a Mustang, you lower its center of gravity. Once that’s done, you’ll have much firmer control over your pony car’s steering, and you’ll feel the improved responsiveness the moment you take your first turn.

By radically lowering your car's center of gravity, Eibach's Sportline springs dramatically reduce squat during acceleration, body roll in corners and nose-dive under braking. By using their proprietary, progressive spring design, Eibach Sportline springs provide the ultimate balance between high performance, extreme lowering and comfortable ride quality. When combined with today's wild 18", 19" or 20" wheels and tires, the result is a car that handles just as white-hot as it looks.

- Race car like handling: Eibach Sportline coil springs give your Mustang the performance suspension upgrade you want.
- Lower center of gravity: Take tighter turns at higher speeds for a fun ride.
- Stop quicker, corner faster and get better MPG: Brake more easily and get better gas mileage.
- Eibach million-mile warranty: Unmatched 1-million-mile warranty for peace of mind.

Approximate Lowering Measurements:
- V6 Coupe = 1.1" Front/1.1" Rear
- GT Coupe = 1.3" Front/2" Rear
- V6/GT Convertible = 1.4" Front/1.5" Rear
- Boss 302 = 1.0" Front/1.8" Rear

Eibach Coil Spring Sportline Set V6/GT 2011-2014/Boss 302 2012-2013 is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Way better handling! I purchased these springs a few weeks ago and wish I had done it as soon as I bought the car! They are well worth the cost purely based on aesthetics, but add the performance gains and there's no question about it. My Mustang is the Brembo performance addition, which came with an upgraded suspension, and these springs still made a vast improvement in handeling. The suspension is a lot stiffer and body roll is greatly reduced, along with a decrease in nosedive during breaking. All these performance gains came with almost no change in ride comfort, these springs are a win-win!

is there any other modifications I need to do along with adding these springs?

Asked by: Ski 2013 GT
We recommend a set of caster camber plates and a adjustable panhard bar. These two items will help keep everything properly aligned.

I have 20 inch front and rear wheels on my 2013 GT, do you believe that these springs will cause them to rub?  If so, would you recommend the pro springs instead.

Asked by: Probers2
You should be fine, but it will all depend on your alignment settings and what size tires you decide to run.
Answered by: CJPP Dave

Will these fit OK with factory 19" wheels? Or, will there be tire rub?

Asked by: Hunter77
You would be fine.

Will these work on a 2012 Roush RS3?  The Roush suspension is already lower than a GT so how much lower would these be on the Roush RS3?

Asked by: Chad112
These springs lower a stock GT Coupe = 1.3" Front/2" Rear.

I want yo lower my 2013 Boss 320 with the Sportline springs. Do I need to get this panhard bar also? I want it to look perfect. I am assuming alignment needs to be done afterwards ? 

Asked by: Bryan302
Although it is not necessary an adjustable panhard bar will center the rear end in the car, it always good practice to have an alignment done when changing suspension components.

Eibach Coil Spring Sportline Set V6/GT 2011-2014/Boss 302 2012-2013 Video Transcript
By Bill Tumas: We've done a lot of typical upgrades to our 2011 GT, including a shifter, a cold air kit, and a pair of mufflers. Another real popular upgrade is going to be a set of lowering springs. Ever since we installed our Boss 302 splitter, the car's been in desperate need of being lowered. So, today, we're going to install these Eibach Sportlines.

Eibach offers two sets of lowering springs to the 2011 through 2013 Mustang; the Pro Kit and the Sportlines seen here. The Sportlines is the more aggressive of the two, which is going to give us approximately a 2"drop in the back and an 1 1/2" drop in the front. The kit includes all four springs and a pair of new lower bump stops.

For this installation, we're going to need a jack and jack stands, or a lift and pole jack, 1/2" impact gun, 13/16th socket, 1" socket, 18mm socket, 21mm socket, 3/8 ratchet, T40 Torx bit, 8mm socket, 10mm socket, 13mm socket, 15mm socket, 18mm wrench, hammer, spring compressor, torque wrench, razor blade, Lock Tight, and safety glasses.

We're going to start with the front springs. We'll start by removing the two nuts on the inside of both sides, which will also remove our strut tower brace. Now, we'll just loosen the outers. You don't want to remove them, but basically just break them free. Now with the car up in the air, we'll remove our wheels.

To remove our original strut, first we disconnect our sway bar, then we'll take the brake line off the back here and, lastly, the two retaining nuts that hold the spindle to the strut. Then remove the bolt in the back here that holds the brake line to the bracket. Remove the little Christmas Tree clip for the ABS line. Now, move on to the two nuts that retain the spindle to the strut. Now, you want to hammer out the bolts. Now, go back and remove the nuts for the strut top. And now we can remove the strut.

Now we need to remove the spring from the strut assembly. You will need a spring compressor tool to do this to safely get it off the strut. Once you have it properly compressed, and it's no longer leaning against the strut top here, you can remove the strut nut. Now, remove the compressor. Last step with the stock spring is we're going to remove the factory isolator and move it over to our new Eibach.

Now, we're ready to put it back on our strut. We'll install the spring on the strut. For the Sportlines, we probably don't need our spring compressor. If you're using a different kind of spring, you may need the compressor to get down far enough. We've learned from the past, the Sportlines are low enough you usually don't.

Make sure the end is seated properly on the strut and push it all the way up against that edge there. We'll install our strut mount, again with the cutout, with the spring. Before you install the strut nut, you'll want to put a dab of Lock Tight on the threads. Press down a little bit and get the nut started. I'll tighten it down. Put the cap back on, ready to reinstall on our car.

Now, we're ready to reinstall the strut assembly. You want to make sure when you put it up into the strut tower, this little notch here is facing outward, lined up with the edge of the strut. Tighten these down enough to hold it in place. You don't want to tighten them all the way just yet. We're going to lift this up into place. Reinstall the nut, and reinstall the bolt for the brake hose bracket. Now, reinstall the clip for the ABS line, and move back to the sway bar. Now, we'll reinstall the wheel and repeat the process on the other side.

You want to make sure, once you put the wheel on, you torque it to the proper spec before driving. Once you've finished the driver's side spring, then we're going to tighten the outer two nuts for the strut mounts then reinstall our strut tower brace. Now you can move onto the rear springs.

Now, we're ready to work on the rear springs. The first thing we're going to do is to support our axle. After that, remove the nut and bolt that holds the sway bar into place, that way we can access the bolt to remove the rear shock, which will allow us to remove our spring. Next, remove the bolt for the rear shock. Now, we're going to lower down the rear and remove our original spring. Now, we're going to replace the bump stop with the shorter one. If you leave the stock one on, you'll have some ride issues because the lower spring allows the bottom out too easily.

Here you can see the installed height difference between the stock bump stop and the Eibach bump stop included with the kit. Lubricate the new one a little bit to install it. There you go, ready to reinstall. We're going to reinstall the factory isolator spring back into place. And you'll want to leave with the bottom end of the coil towards the back of the car.

Now, we'll jack the rear back up into place and lift it until the shock lines up with the hole. Slide the retaining nut in the back, and slide the bolt through. Now, you want to leave the sway bar disconnected and repeat the process on the other side. Once you've done the other side, then you can reconnect your sway bar.

When we reattach our sway bar, we want to make sure both links are inside of the exhaust. If you tighten one up, you won't be able to get the other one installed. And the installation is finished.

Our Eibach Sportlines gave our 2011 the look we wanted: the car sits flat, it's nice and low, the wheel well gap is almost gone. Best of all, it's going to be a huge improvement in handling. Installation should take you around two hours. You'll be back on the road in no time.
