Best Springs on OEM Brembo shocks/struts

My 2012 Brembo GT has 4,000 miles on the odo and I have finally had enough of the 4x4 look. I'm seeking suggestions and advice on which lowering springs would work with stock Brembo shocks & struts. I know it's in my best interests to replace the shocks & struts as well...and eventually i will, being that my Mustang has low mileage i wouldn't mind sticking with the stock stuff for a while.

Thank You all for your help

This is a good question that is a bad question. The reason being that there is such a wide variety of opinion and none of it will take into account your peculiar sensibilities. And the "experts" opinions are worth two small farts when it comes to this. Second, nothing will ruin your driving experience more than springs that are too stiff. Potholes will feel like an ice pick to your medulla oblongata. expansion joints will slip a disc. I know. I have been through several spring sets until I finally settled on stock Boss springs. An incremental performance advantage that ruins your everyday driving experience is not worth it. The only thing you can do is learn by experience. Other people's experiences won't help you much. The bottom line is what is your tolerance level? Only you know. General rule is: the younger you are -the stiffer spring you can handle.

I know you have explained your reasoning for keeping the stock struts and shocks. But, If I had not already modded mine, this is what I would do:
FRPP Handling Pack - only $325 - SVTPerformance

Definitely a good deal!

I saw that too. For somenoe who just wants to lower, that's great. But I'm going with P Springs and Koni STR.T's after some more homework.

None. First off, why do the same job twice---get the springs and the dampers at the same time, or at least do the job at the same time. Second, it's well established that the stock dampers don't actually do their job very well. So adding a lowering spring that essentially is stiffer than oem will ask the shocks to do even more more work that they already aren't very good at.

If you look up the Best Drivers Under $35k issue of car and driver for a year or two ago, they published damping curves for all of the car, including a BBK mustang GT. It was vastly worse than every other car being tested---miata, GTI, 370z, Evo, and a couple of others. You wouldn't notice a change in ride height, but your handling would probably improve if you just replaced the dampers with something better.

But yeah, do it all at once if you can.

honestly search some more on this forum before you buy springs only. might change your mind and get dampers as well especially that Konis are on sale big time at Strano.

For it its do it once and do it right. when you lower, the car on stock dampers, the damper are not shorter and don't take into account the drop.
Vorshlag explains it best Vorshlag Motorsports-Bilstein BTS Test- 2012 Mustang GT - YouTube and they know all about handling since they race their cars

The only springs I MIGHT do without a strut/shock upgrade would be the FRPP P springs since they only have a 1" drop. I would never do something like Sportlines with the OEM's on there.

Technically to lower these cars RIGHT you need the springs, struts/shocks, adjustable panhard rod, new strut mounts and camber bolts. This is my plan as I not only want it to look even better, but I want it to ride and handle better as well.

You can probably get away with Eibach Pro Kit without upgrading you OEM shocks/struts. It gives a 1-1.25 drop. Anything lower you will need to replace the shocks/struts.

What are you trying to achieve? Looks, ride performance etc...

PM or Call me directly. I'll be more than happy to help you with what you are looking for.

Thanks

I agree, we have many satisfied customers running our Springs on the stock struts/shocks.

That being said, with the deal we have right now.....I wouldn't recommend it.

Check out the BMR Spring / Koni STR.T Package we have right now, for a limited time:

BMR / Koni Package - $465.45

Yes, that is (4) Koni's and (4) BMR Springs for $465.

To touch on the stock strut w/ Lowering Spring topic....for years we have not seen issues, but I have had a few people recently experience stock strut issues on our springs. I do not believe this is indicative of what "will" happen, but I believe it is a good idea to incorporate a quality set of shocks and struts into the package when lowering your S197.

Happy Modding!

Before I fully upgraded my suspension (see sig), I too wanted to get rid of the 4X4 look and went with the Ford Racing K-Springs. Overall drop is about 1.5" front and rear. It looked great and rode well - plus the price was right.

^^What he said. The Eibach Pro Kit springs (which are the same specs as FRPP K, Roush DUB, and UPR Pro springs) are probably the most common choice. I had them on my car with stock struts & shocks, and now with Konis. I'm very happy with them. They corner well, straight line grip is still good, and ride quality is reasonable.

Hey Kelly,

I think your warning with using factory shocks and struts should be a no brainer for everyone. If you change something like springs, you will affect something else, sometimes for the worse. The factory hardware was meant to go with factory hardware. Your honesty with some cars running into blown dampers is and of the highest integrity. Do it right the first time and only time.

With that said, I take it the springs in this package are fully compatible with Ford Racing GT500 strut mounts, yes?

They are absolutely compatible with the 2011+ GT/V6 style Upper Mounts AS WELL as the 2005-2010 and 2007-Current GT500 Mounts.

Thank you for the compliment. I appreciate it.
