    Good quality springs. Stance is a lot better than stock, and has good ride quality. I would also reccomend caster/camber plates.

    Will these springs be ok used with stock shocks and struts? Wanting to know if I'll have to buy new shocks and struts as well.


    • You can definitely install these lowering springs with you stock shocks and struts. But with that said, you'll find that on your 1996, you'll likely have much better ride quality and performance when adding new shocks and struts as your stockers have just shy of 20 years of wear and tear on them. Hope this helps!

    Will I need Caster/Camber plates with these? Running 17x8 on the front with 245s? Thanks in advance.


    • The BBK Lowering Springs - Coupe & Convertible - Specific Rate (79-04 GT, Mach 1; 93-98 Cobra) will not require caster camber plates for the install, however we do recommend them to help fix the alignment.

    I assume a GT Convertible will drop more than a coupe due to the weight. How much more drop? And how much difference is there with and without isolators? Thanks!


    • When using these BBK Lowering Springs on a convertible, the spring will settle approximately 1/4" lower than a coupe. The isolators will add about 1/4"-1/2" height after settling down as well.

      Great springs

      really revived my 14 year old suspension with improved handling and response. significantly reduced body roll and nose diving during breaking and gave just the right amount of drop to give a nice clean look to my ride. great cheaper option to the more expensive springs, and an easy install that I knocked out in about 3 hours.

      BBK Springs

      The springs went on easy and they make the car look much better and handle much better. The only negative was the lack of instructions with the springs. Not having done this before I had no idea the fronts are different then the backs till I looked. That would have saved me 20 min while I tried to fit the wrong spring.

      Great Product !

      For those looking for quality springs that don't bite the wallet BBK is the way to go. It dropped my 04 convertible GT about 1.5" on the front an about 1.25" on the rear giving it a really nice stance and a smooth ride. I'm very happy with this product thanks AM I will recommend these springs to anyone that asks where I got em from.

      lowering springs

      Great overall product. Lowered about 1 inch overall. Cornering speed has increased by about 15mph which is AWSOME!!! overall great product. Would have gotten 5 stars if it lowered the full 1.5 in like the kit said.

      Perfect stance for a convertible

      I purchased these because they were cheap. Also, it was between this and another option due to my convertible being a heavier model. I was skeptical about the outcome but wow, did these springs exceed my expectation as far as closing the wheel to fender gap. From fitting my whole hand between the wheel and fender, I now can only fit about three fingers. I have not measured it but im willing to bet the 1.5" drop is on point. handling turns is better. If you don't mind a bumpy ride then just invest in some shocks and struts but for 200 bucks you can't beat the appearance on your lowered mustang. I don't mind the bumpy road, I like a lot of feedback from my ride.

      great buy and love the new stance

      First off, don't use spring compressors, that's why it took me all day. The bars got wedged and took me most of the day to get it out. Take a jack and place it under the lower control arm for the easiest way. Beware the bottom coil on the spring will more than likely break, making it a fun afternoon for you! Installation is really easy but look at your sway bar bushings as well as you sway bar link and your ball joints. I did these too and the ride is 100% better. It took the play out of the steering wheel and takes curves a million times better. I only replaced the front because the back are weighed down by my sub. The ride quality is better than stock and I'm still not scraping anywhere I've been. Overall one of the best additions to my car.

      Just the way You want it

      i got these springs because the price was good and it dropped it just enough to get rid of that 4x4 look. I love these springs. the car handle like it should of from the factory. I also went with the bbk ones, just because most of the stuff on my car is all bbk, and i've been very pleased with all their products so far.

      MI have had 3 ustang GTs over the yearsa nd I have always tried to soup them up for a bargain, settling for Japanese knock-offs of springs, intakes etc. My friend who has a 98 Cobra reccommended American Muscle to me and with teh free shipping it was CHEAPER than teh knock offs to buy BBK Progressive Rate Springs and the Stang handles a million times better!!! I wish 10 stars was an option. BEST ONLINE VENDOR I have dealt with in the last ten years! Keep up the good work !!

      BBK lowering springs

      Looks good and handles better. Being my mustang is a convertible it really did drop 1.7 inches instead of 1.5 was easy to install. I lifted the car in the shop at my job and by myself i had everything done in about an hour and a half. Very easy with a lift didnt even have to use spring conpressors

      Fantastic ride, must buy. Can always trust BBK.

      Just installed my lowering springs, and let me say it is a convertible and it is a cobra so it's gonna drop a little lower, Let me say The ride is amazing and it handles beautifully, I can't wait to break them in more. But I also installed SR performance rear upper and lower control arms. The previous owner had KYB AGX Adjustable shocks and struts installed as well. Also, It is a must to get rear upper and lower control arms and a nice set of struts,shocks, and quad shocks/dampeners- to even out the ride quality. I highly advise not installing lowering springs with stock shocks and struts. Overall good ride quality, I'm confident in not scraping.

      Car looks great lowered

      Lowered car a full 1.5 inches, ruff ride but that was expected. A spring compressor is a must, no way to remove rear old springs and install without. Fronts will need someone to help pry and push the new ones in, not a one man job.
