  • The Ford Racing Lowering G-Springs - Convertible (79-04 GT, V6; 93-98 Cobra) will not fit a 2003 Mach 1. If you are looking for Ford Racing lowering springs that would work, I recommend the Ford Racing Lowering B-Springs - Coupe & Convertible (79-04 GT, V6, Mach 1; 93-98 Cobra) item #50151 (www.americanmuscle.com/b-springs-7904.html).

What makes these springs only compatible with convertible Mustangs? The only difference I can see between these and the "B" springs are that the front and back drop an equal amount on these, whereas the "B" springs drop the front more.

  • Convertibles are actually a bit heavier than coups, so because of this, there are often springs that rated specifically for one or the other. Technically, you could put these springs under your mustang, however it won't quite drop as low as advertised, and it will be a much stiffer ride than the designed intention. For this reason I would suggest finding a spring specifically rated for a coup.

will I have to replace the Castor Camber plates when installing these springs?

  • Caster camber plates are recommended for anything over a 1 inch drop. While they're not essential for a good alignment with a 1.2 inch drop, they are definitely necessary for a 'perfect' alignment.

    Good allaround springs

    I took off a set of racing springs that handled like I was on rails, unfortunately it was rattling my interior apart. These are stiffer than stock but still have a good ride. We had to install the fronts 2 times because the car looked like a 4x4 still after we took it off the stands. We pulled it all apart and took out the top isolators. This made them look much better. We left them out in the rear to keep the measurements consistent. These make the car level so the tail drops more. The front looks perfect, but I think the rear isolators will get put back in when we do the gear swap. It looks just a touch too low. I docked them a star for having to remove my front isolator to look like a lowered front. After a couple days of settling it looks great. They come in the red Eibach box so you do the math what they really are. Overall I am happy with them.

    Ford Racing "G" Springs

    Let me first say that the AM staff (shout out to Mike @ ext. 102) are awesome fellow mustang enthusiasts that made my purchase a pleasant transaction. I chose these springs for my '99 35th special anniversary package GT convertible as part of a complete suspension restoration / overhaul. My goal for the springs were to: 1) Fill in some of that wide gap between tires and wheel well AND 2) Maintain excellent street road manners. It did both jobs very well, and as a side bonus did contribute to improved handling. Before purchasing, I did extensive research on various forums and could not find much information about these springs. When I recorded the order, I was alarmed when it came in an Eibach pro-kit box. Turns out, as I found out discussing with the AM staff, these springs are engineered by Ford Racing but manufactured by Eibach. If you look closely at one of the product pictures, you will see the Eibach logo on the spring. I am happy with my choice. With new poly isolators, my car dropped about 1". It gave my stang a great stance with a very slight "raked" look. The drive quality is outstanding. The car feels firm, but not stiff. The spring rates match very well to the dampening characteristics of Koni STR.T orange shocks/struts. I can't comment on how they perform at the strip or track, but if you are considering these for a street-driven convertible...you won't be disappointed.

    Great look... Not too low, ride is still good

    Mounted in a GT Convertible... It got rid of that 4x4 factory look. Mild drop, needed alignment. No special caster/camber plate needed. Factory strut mount has enough adjustability built into it to get the front end back into spec. I am more careful about potholes although.

    Great spring for daily driver

    Good ride, less nose dive when braking and better steering response. I was expecting the car to lower a bit more but i like it that way. I recommend to instal new spring insulator all around for best result. Installation in the back is a peace of cake but i recommend an extra pair of hand to do the front.
