First, my English is Second language. Sorry for bad English.


Now, I have 2012 Mustang GT with Eibach Pro-Kit Springs for 11-14 GT and Eibach.

I have droven over 53000 miles and started give me clunky noise on strut mount.


I want to go with KONI STR.T Front Strut for 05-10 and GT500 strut mount.


The question is, can I keep the Eibach Pro-Kit Springs for 11-14 GT??

or should I get lowering spring for 05-10 GT??


Sorry again for English and I hope everyone understands and give me a good help.

Thank you.

sjooyoon,

First off welcome to the forums! Your English is great for a second language. It's much better than I could do with any language, other than English haha.

You'll be fine with the 05-10 Koni STR.T struts and GT500 strut mounts. There's no need to change your Eibach springs. The Eibach lowering springs are made for all S197 Mustangs '05-'14. There's no need to change them for your setup.

Hope this helps clarify things for you. Let me know if there's anything else I can assist you with!

Thank you, Shane.



You mentioned 'The Eibach lowering springs are made for all S197 Mustangs '05-'14'.

When I google 'Eibach Pro-Kit spring' for S197, there are two different product numbers.

First one is for '05-'10 (product #35101.140)

Second one is for '11-'14 (product #35125.140)

This is why I am confusing.




However, when I google other lowering springs, they are for '05-'14, for example, SR Performance, Steeda Springs and Ford Racing springs.



Anyway, I will assume those two Eibach springs are same.


I will try to install them to my '12 Mustang and I will see if it fits or not.



Thanks again, Shane.

Sorry to add additional confusion!

Some companies like Eibach make different spring rates for 05-10 Mustangs compared to 11-14. While others have a spring that covers all years 05-14. The difference between the springs that Eibach makes has to do with their compression weight rating. It's slightly different for those years since the cars aren't exactly the same weight front to back.

However, the installation and fitment is exactly the same for all 05-14 lowering springs. You'll still be okay with zero fitment issues using those springs!

On my '11 GT, I have the KONI STRT's (I think they where for the '10) mounted on GT500 mounts, combined with the STEEDA Sport Springs, I love that set up, it really made a great improvement on the handling of my car VS the *&%^# stock set up.
