Community question: What are your favorite modifications that you've made to your S550 mustang?

11 Jan 2017

For starters, I’m glad that I invested in wheels, tires, and eibach springs as 2 first mods. It mixes function with looks, which is a perfect balance in my book! (Car pictured is @kevcity ‘s ecoboost). His car is probably my favorite modified S550.

Though it won’t be found on this list, I know what everyone’s favorite is:
Owner swap!

My favorite modifications are my steeda transmission bushing insert (mt-82 only). Because it stiffened up my shifts and for 30$ (huge bang for buck) it changed the entire feel of the transmission, making it soooo much better and less likely to lock me out of gears. Second is my Bama performance tune. The tune made the engine feel like it should’ve from the factory, with more torque and aggressive turbo spool and much faster revving. Lastly my exhaust cutout valve (custom fabricated) because it lets me have two different exhausts in one. With the valve open its a monster! It sounds deep and agressive without any rasp unlike any off the shelf exhausts. With the valve closed it sounds like the normal stock car quiet, no drone, and no unwanted attention.

Although I’ve done lots of mods so far, my favorite by far has been my RTR white shift knob: cheap, easy, stylish, and feels so much better than the tiny stock one.

What else have you done?

I haven’t done much to mine. And probably won’t. It’s being sold in 2018 for a c7 zo7 but I’ve done springs and exhaust and gt350 wing.

The springs helped the car so much. I’d definitely recommend doing them

I’m planning on getting a GT350R wing, and am an amateur in the modding scene. Did you install the spoiler yourself, or did you get a shop to? Additionally, would a dealer install it?
