Improves Handling. These Ford Racing "C" Springs will lower your Mustang approximately 1" giving it a more aggressive stance and a lower center of gravity greatly improving your pony's handling over the stock springs.

What is difference between C and B springs from ford racing?

cruizer

  • While C-Springs and B-Springs have the same drop, the difference between the two are their spring rates. C-Springs are Standard Rate Springs, which means they are at a constant rate and won't vary while driving. These are better suited for those looking strictly for the performance gains and don't mind a stiffer ride. B-Springs are Progressive Rate Springs, which means the spring gets firmer as it gets compressed. These springs are great for daily street driving, keeping a more comfortable ride.

Question Resolved

RECOMENDED OTHER PARTS? SHOULD ANY OTHER PRODUCTS BE PURCHASED WITH THESE SPINGS, SINCE THE FRONT END IS BEING LOWERED WOULD CASTER CAMBER PLATES BE NECESSARY, OR RECOMENDED?

MATTWO

  • I'd recommend replacing your factory, worn down/possibly dry rotted isolators with new front and rear polyurethane springs isolators. They are more durable than the stock counterparts, will last longer and will prevent any metal on metal noises. With this spring kit, you most likely won't need CC plates to obtain proper alignment. The general rule of thumb is any drop over 1" should also install CC Plates. To my knowledge, most customers installing this kit have not needed them. You can always install them later if you find there isn't enough adjustment stock. Hope this helps!

I have a 2003 Mustang GT, with 20 inch wheels. Will these fit with the wheels I currently have on there?

guttaboystang

  • The Ford Performance Lowering C-Springs - Coupe & Convertible (79-04 GT, V6, Mach 1; 93-98 Cobra) will fit fine with the 20 inch wheels you have! I would not go anymore then a 1.25 inches with the 20 inch wheels.

Question Resolved

Which of the ford c-springs are the front and the rear? Mine are not marked

qazwsx

  • The springs will look the same as the ones already on your car. The only difference is that the lowered versions will be shorter and thicker than your stock springs. (The mounting ends will look the same as the stock ones,) Rule-of-thumb, the rears will have one end that is narrower.

Is an alignment necessary after installing these springs? I know an alignment would help, but will it be ok without one? Or will tires start wearing unevenly?

JarrettD

  • Lowering the car any amount will affect camber in the front alignment. Tire wear will be noticeable in a short time so get it aligned asap!

Are spring isolators needed? Do you have to use spring isolators when installing new springs or can they be left out.

stangcrim

  • When you change out your springs, we highly recommend you swap out your old, worn out isolators. The new polyurethane isolators will last much longer than the factory set and will prevent any unwanted metal on metal noises that can result from installing springs without a new set. If you have any additional questions, please don't hesitate to contact us!

    Great lowering spring

    I ordered these for my 2004 GT. I was looking for a little more aggressive look, but didn't want to slam it. The Ford Racing lowering C-springs are the same factory spring that was equipped on the 2003-2004 Mach 1. Or so I've read. Install was pretty easy, and I was able to do it in my garage with basic hand tools, and a floor jack, with jack stands. Total install time took about 4 hrs. Ride quality is OEM. Not any different from the factory springs IMO. After it settles I'm looking at about an inch of drop on all for corners. And that's with isolators installed on all four corners too.

    Perfect drop

    My convertible GT looks and corners sweet. As for the install recommend removing the front brake calipers so you can get a clearer swing with the hammer, takes a few good wallops alternating from front of lower control arm to back side. For the rear I pulled the bolts and lowered both lower control arms at the same time with a floor jack under each. Worked great, the rear springs came out no problem and re-installing the new ones was a breeze. Thanks AM

    Very Nice

    I had these installed on my 04 GT when I bought the car a year and a half ago. Popped the trunk on the dealer lot and boom they were sitting there along side some Tokico Shocks and Struts. You can tell a big difference between these and the stock ones. Sitting next to a stock 99-04 Mustang and even an 05-09 Mustang you tell can you sit lower. If you're looking for a lower stance the Eibachs are better. I've sat next to a guy with Eibachs on his Mustang and sits lower than mine These combined with the Tokico S&S makes for a real nice handling Mustang.

    Offers a Much Better Stance!

    These springs are great. They get rid of the 4x4 look and give my Mustang a better better stance. Seemed to help the handling as well. Great look and ride for those not looking to slam their pony with aggressive lowering springs, these are just right. Allows me to easily fit the larger wheels on the back too.

    I should have installed these on my 5.0 years ago. It really gave my car an aggressive stance. It dropped the front approximately 1.25" and the rear 1". This is an awesome look for all foxbody stangs without sacrificing the ride quality. American muscle is a true must save bookmark for all of your performance needs!

    2003 Mustang V6

    I installed the Ford C-Springs on my 2003 Mustang V6 convertible. It dropped the front by 1 inch and rear by .5 inches. The manufacturer indicates that these springs are designed for GT models & have not been tested on V6. It worked on my V6 very nicely, except it was .25 inches higher than the estimated drop. It made my Mustang look more beautiful and did not effect the ride quality at all!!!

    Ford Racing lowering C-springs

    I was running the original 1986 v6 springs and going from that to this was a huge difference. The car sits about like the description said, the car can actually take a turn with some speed now. Ride quality is stiff but not bad on your body. Probably the best thing I have bought for my mustang. Would recommend it to anyone daily driving a fox body but likes to have some fun too.

    Ford Racing Springs get an A+

    I picked up a set of the Ford racing springs and went with the C spring because it was the stiffest they had to offer and my mustang is my play toy not my daily driver. I have no regrets with the C springs they are paired with bilstein shocks and struts and it's now a whole new car. It is very stiff but the overall ride quality is much better than I expected and I would honestly recommend these to anyone looking for better handling because I don't see where you would have an issue even as a daily driver. Also id like to note one of my past mustangs I used the BBK springs and spring vs spring the Ford racing are hands down better.
