Improves Handling. H&R Super Sport Springs will lower your V6 or GT Coupe for a much more aggressive stance and a lower center of gravity which greatly improves your pony's handling over the stock springs. H&R Super Sport springs are comfortable enough for everyday daily driving and offer more control than the original stock springs on the street or the track.

Application. This set of four H&R Super Sport Springs are designed for use on the 1996 to 2004 V6 and GT Ford Mustang Coupes. Excludes IRS-equipped 99-04 SVT Cobras.

Please Note. When installing new springs you should also replace your old worn out rubber Spring Isolators with a new set of Polyurethane Spring Isolators, see drop down option above.

Technical Note. These springs will not fit 1999 to 2004 SVT Cobra's with Independent Rear Suspension (IRS) or GT Mustangs converted to IRS.

Will LT headers be a problem with the drop? I want to purchase these lowering springs but I just installed long tube headers. I'm just wondering if the drop will make the car too low and start scraping? I wanna lower my car but I'm worried that i might damage my exhaust system

I have got lowersrings on my mach 1 had on problem withgrown clearance
Unfortunately, since longtubes hang lower than the factory exhaust, lowering your car would increase the risk of damaging your longtubes, especially if you must frequently interact with speed bumps.
1.75 inch drop in the front. I would not do it with LT.

18 inch rims with this lowering spring set up All right so I have a 1999 mustang gt and I have some 18" Bullit rims on it I wana lower my car but idk if it will rub with theeze springs and with the tokico hp shocks and I wana no if I drive over a speed bump or pot hole will my tires rub of I have the back seats and front seats with people if any one can answer me these questions it would make my day thanks ,

I highly doubt you'll have an issue. I have seen lots of pics of cars with 18" wheels that are lowered further than these springs will take you, and they don't seem to have trouble. Get them and have fun!
I have these springs and the tokico hp's with 18's. I have the front 265/35/ZR18 and the rears are 285/35/ZR18 Sumitomo's, and I have had no rubbing issues. However, while these will improve the handling of your car, it will also make the ride a bit more harsh especially when loaded down with added weight.
I run 18s with these shocks and never rub. I have 285 35 zr18s in the back and have never had a problem. I've never had my car full of people so I can't be sure that a few hundred more pounds wouldn't create a different response. But these spring are great so do it.

I know that CC plates are suggested for this mod, but what else would I need to make sure nothing wore out quickly.

You would also want to swap out your old, worn out rubber front and rear spring isolators with some new polyurethane isolators. These would ensure that your new installed springs don't make unwanted noise and they will last much longer than the stock rubber! Check out the links below!
I would replace the front struts at the same time or some time in the near future. I run KYB struts with my H and R springs and am highly satisfied.
I had the same questions when I started buying parts for my lowering project as there are so many opinions and different setups out there. I went with hr super sport springs, new poly isolators, tokico HP struts, koni STR.T shocks, And MM CC plates and I'm very happy with the results. The CC plates are required to get it back into spec after the lowering springs are put on, the stock plates won't allow for enough adj beyond an 1" of drop. Hope this helps.

Would I need new shocks and struts or could I get by with just replacing the struts?

Both shocks and struts would be recommended if you are lowering the car because more than likely the stock shocks are worn out and they also will bottom out due to the lack of travel. Bilstein HD shocks and struts have plenty of travel for lowered cars, I highly recommend bilstein with these springs.
When I installed these on my '02 GT, I replaced the front struts. A few months later I replaced my rear shocks. If you have the cash, I would do them both at the same time. But you don't HAVE to replace your rear shocks.

Will new isolators create less of a drop? I purchased these springs and plan on installing them within the next month, I have also purchased the new isolators. I was wondering if putting the isolators on will cause less of a drop for my stang? I want the most drop i can achieve.

The isolators won't cause the springs to drop any less than advertised. You should always replace your old, worn out isolators when installing new springs to prevent any unwanted metal on metal noise. I'd suggest using your new isolators in combination with these springs. You'll definitely be happy with the drop - these springs make the Mustang look so much better than stock!
you must install the isolators, they prevent metal to metal contact which will cause noise and metal wear, you will love the drop after they settle @ 2 weeks or so
I've always used isolators because I want it done right, and I don't believe they would cause the springs to not go to their lowering potential.

will these fit with 315/35/17 tires in the rear and 275/40/17 in the front? 3 answers

Definitely! We offer several wheel and tire packages with 17x9 and 17x10.5 wheels with those exact tires and they will fit without issues up to a 2" drop. You will have no problems installing these springs with those tires!
yes they will, i have the same tire sizes and they look great!
Yes I believe they will fit that tires style with no problem.

The drop. Will I have enough room for all-season tires once the car is dropped? I notice in the pictures, most have replaced their wheels to low-profile look. Also, I have 18x!0" wide tires in the rear....will this also be a problem if I get these super sports. And I plan on getting a roush body kit I think next year though. 2 answers

For an 18x10 wheel, you should be using a 285/35-18 size tire for proper fitment on the 96-04 Mustangs. Using that wheel and tire size combo (an all season or whichever style you wish), you can drop the car up to 2" without any issues. This H&R Spring Kit has a 1.75" front drop and a 1.6" rear drop so you will be just fine! With the drop being over an inch, I'd highly recommended a set of caster camber plates to correct your alignment and new front and rear spring isolators for a smooth and quiet ride!
With the 18's, most have gone to a 35 tire. I had 18x10's on the rear with 285/35/ZR18 Sumitomo's and they fit great. You won't have any problems with going wide with the SS springs.

Sportline Springs

These springs are a awesome way to get rid of the horrible wheel gap the 99-04 cars come with from the factory. Although there are cheaper options on the market I believe these are superior quality. Note: I have had these springs for about a year and a half now and they are pretty stiff. If you live in an area with bad roads or a lot of pot holes you will feel every little bump in the road.

Gets better with time

Make sure you have all the tools necessary (breaker bar is worth it's weight in gold) and this project is pretty straight forward and easy to accomplish. These really made my off-road Mustang look like a sports car! The initial drop looks good, but once the springs settle, looks EVEN better. New shocks/struts are suggested as the car tends to bottom out when fully loaded, but not necessary right away if on a budget. No more lean in corners, and the car holds the road tight!

HRs on my Bullitt

These springs are literally night and day comparison with the stock bullitt springs, feels like a new car. Dropped my bullitt a good inch and a quarter. WILL NEED TO GET ALIGNMENT DONE!! Fairly easy to install the rears but the fronts were a bit of a challenge. If your thinking of putting these on your mustang... DO IT!!!!

H&R SS Springs are by far the BEST for any SN96

This is a great set of springs. The drop was as advertised, and the stance is perfect! I have had many compliments since the install. I paired my springs with a set of Tokico HP struts and a set of Koni STR.T shocks in the rear. The ride is firmer than stock of course but it feels great! Handling is much improved and I can't get over how great it looks now, the way it should. Don't be afraid of the drop as I have had no clearance issues at all and if you have 17" wheels as I do, the 1.5" lowering kits will probably be disappointing unless you have 18" wheels or bigger. Overall an outstanding product and of course great service and shipping by AM!!

Great springs

It took me about 3 hours to install these springs, and hour for the rear and an hour per side in the front. I did not install caster camber plates, and I did not get it aligned. With that being said, I am extremely happy with these. I installed them with new iso's in both the front and rear so the drop isnt as dramatic as it could be. the alignment is fine, although i have some negative camber... I installed 9 inch wheels and tires a while back and it had positive camber once i did that. These springs bring me back in to spec + a lil more. I know I will have some inner tire wear, but I dont care. The handling is much more predictable and the ride is a bit more firm. Overall I am very happy. For those of you have longtubes, be prepared to take it easy on bumps. I have to enter my driveway at an angle otherwise I scrape. The same thing goes for speed bumps. I have already dented and scraped the heat shields on the cat's on my bbk x-pipe.

I'm glad i went with these springs

They feel great with my Tokico Illumina shocks. I used my sock isolators. It took a few weeks for them to lower my car a little more. You should definitely purchase cc plates for a proper alignment when buying any lowering springs.

way better

I had bought these to replace the sportlines springs on my gt.smooth ride turn sharp and body roll is less than sport lines. Much stiffer as well. I would bottom out with tokico hp shocks. H&r super sports are by far a better product. I had sportlines for 2 years so I know the difference. I will be installing bilstein this week end.

Amazing Springs, Amazing Stance

My previous stang (99GT) had BBK lowering springs on it. I thought the look was great, but wanted something a little more aggressive for my new 03 GT. These H&R Supersports look amazing and give my Mustang the perfect stance. In my opinion, 1.75'' in the front and 1.6'' in the back is what everyone should do. Rides and handles much better as well! I have these combined with Tokico Blue shocks and struts and my car rides like a dream.

A great early modification

What can I say that hasn't already been said? At any rate, I hope this will help someone decide whether or not these are right for them. Let's start with the easy part first; they make the car look fantastic. After installation, your car will look the way it should have the day it left the factory. It's truly amazing how much a difference 1.5 little inches can accomplish visually. Now let's get into the aspect that will affect YOU more than anyone else, since you have to drive the thing. Again, what a difference 1.5 little inches makes! The ride quality didn't suffer appreciably, but there were some surprising improvements. First off, being a road course guy, I noticed the quicker and smoother turn-in the night these were installed. Furthermore, it recovers more smoothly when exiting a turn. Bump steer was never a real issue, but now it's all but gone. I sort of feel as though these springs improved the suspension geometry, and I tend to think Ford put a bit too tall of springs in the car from the factory for reasons unknown. With these springs, the car behaves much like a BMW 3 series, which I think is a very good benchmark for an "entry level" sports car! :) If you drive a high mileage car like I do, these will cause your shocks and struts to show their age; you'll experience some shimmy, albeit very minor. I'd recommend grabbing new ones at all four corners, and while you're at it, get some good tyres and rotors and Hawk pads from AM (these are all things that benefit from one another). When finished, you'll have a car that is terrific fun to drive with looks to kill, without the gremlins (and the interior space, but hey) of a 330ci.

Great Springs

I bought these along with just about every other suspension component you can put on a 96 GT and put it all on at once. It all came together great and the springs lowered the car to what I would consider to be the perfect ride height. My handling was improved dramatically although I cannot give all the credit to the springs, but altogether a great product.

In Love With These Springs! Great Stance & Handling!

The review title sums it up nicely. The springs dropped my car nicely, but not too low that I won't scrape most driveways, even with my Mach 1 Chin Spoiler. The ride is harder and more bouncy, but I like that. It gives me that lowered race car feel and the confidence to take corners. Speaking of which, it handles like a dream and turns almost as quick as a go-kart. This is a must-mod for your Mustang, and I plan on getting these springs for any future Mustangs I own.
