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!
Honestly if your mustang is rides good an your shocks/struts are still good I wouldn't worry about it although I would replace the isolaters
My stock struts worked fine. Being an older car I did have other issues. I needed sway bar bushings as well as the sway bar end link kit for the front. Both had old worn out bushings. It may be different for yours but I would have them on standby just in case. I wish I got the camber caster plates because it goes down to the point it cambers out. Not extreme but it does wear the inside out pretty badly.

headers? I have long tube headers and was just curious if they would rub or scrap with these springs?

No they will not scrap unless u hit a big speed bump but in that case any exhaust will scrap
I have bbk longtubes and every once in a while if I hit a speed bump a little too fast they will hit since the headers are the lowest part of the undercarriage. It's always happened when I was in a rush and not thinking. You just have to be more careful with the shorter speed bumps. The lowest point of the headers is about 3" off the ground.
I have lower springs on my mustang with long tube headers, unless they hang REALLY low it shouldn't be a problem. If you have 3 inches of clearnace now from the header to the ground I don't see any way of these springs being a problem.

It says 79-04 V8. This wouldn't fit an 01 V6? And if so, why not? I thought the GT and V6 had identical suspension parts and fitment.

Hi.i own a 1990 mustang convertible. Am planning on installing full length subframe connectors.will i have clearance issues with bbk lowering coils?

While these BBK Progressive Rate Lowering Springs will lower the vehicle, most jacking rails will stay in-line with the pinch welds so clearance may not be an issue. If the jacking rails extend past the pinch welds then there may be some issues.

Will I need Caster/Camber plates with these? Running 17x8 on the front with 245s? Thanks in advance. 2 answers

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.
The BBK Lowering Springs - Coupe & Convertible - Specific Rate (79-04 GT, Mach 1; 93-98 Cobra) will most likely need caster camber plates. The issue is, there is no right answer, every mustang reacts differently to being lowered, however it is more than likely that you will need them.

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! 1 answer

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.

Spring isos Are spring isos needed or do I have to order them with these springs. 3 answers

You should definitely replace your front and rear spring isolators when installing a set of new lowering springs. They are more durable than the old, wore out stock isolators and will greatly improve your handling and steering response. They will also prevent any unwanted metal on metal grinding, keeping your ride smooth and and quiet. Hope this helps!
I would, when I replaced my springs my old isos were all busted up an worn. Definitely worth the money
I would never replace springs with out new isolators, they won't come with these springs so make sure to order them.

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.

BBK Springs

These springs came on the car when I bought it, but I have ridden in many SN95 mustangs before, so I know that these are a very good improvement over stock. There are definitely springs that can get you lower, but because I have a cobra, the extra engine weight makes the springs settle a little lower than a GT. Very good springs for the money. Not too stiff at all for daily driving, I like these.

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.

Great Spring for the Price!

Installed these with a set of Koni Yellows intended for a DD/DE 2001 Mustang GT. Set them to 1 turn front and .75 rear (found the rebound was a little too firm when corning at speed over bumps). This is a great combination. I have yet to feel a single jarring moment. It is not too stiff for a DD with the koni's and is plenty stiff enough for a DE car too. Allows just enough body roll.

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.

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.

Lowering springs

These springs are a great impovement for handling and appearance with a nice level stance. The kit comes with detailed instructions as needed. ...and overall, a somewhat easy installation for the average wrencher like myself. Make sure to read intructions though; other wise, the car won't sit even.

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.
