CC Plates? Shocks and struts? Would I need to buy new shocks and struts along this kit if I still have the factory shocks and struts on my 2003 v6? Also, would I need to get cc plates since it is on that 1.5" borderline for a correct alignment? I am 17 and haven't dealt with this sort of mechanical difficulty with so many possible options. Any help would be great!

  • If you have an '03 V6 Convertible, this is the right kit for you. However, if you have an '03 V6 Coupe, you'd need this kit instead: You will want to purchase the CC plates to correct your alignment. General rule of thumb, any drop over 1" requires the CC plates to adjust the suspension to the proper toe and camber. Doing so ensures full life of your suspension parts and will prevent uneven and excessive tire wear. I'd also suggest purchasing new polyurethane front and rear spring isolators. They won't crack or dry out like the stock rubber does and they provide a cushion for a quieter ride. You certainly can use your stock shocks and struts without any problems. However, it's recommended to replace them to get the best handling and ride comfort you can while lowering your car. If you'd like some pointers on exactly what parts you want to get with your springs, please give us a call! We can answer any questions you may have and make sure you have the set up you are looking for!

315/35/17 Already have these installed on my 03 GT but, I am curious as to if they will be okay running with a 17x10.5 315/35/17 tire. If anyone of you out there have done this please let me know!

  • That is one of the most popular combinations - 315/35-17 and lowering springs. You won't have any rubbing or clearance using that wheel/tire combo and these Pro-Kit Springs. Check out the customer images for some examples - they look awesome!

    Eibach rocks

    April 18, 2011

    I have a 2001 Bullitt (lowered 3/4 from the factory), these springs were pefect, just the right amount of drop, subtle yet noticable, 1 inch in the front and 5/8 in the back, the handling has greatly improved and the ride feels the same as stock. Only now it stays flat in the corners, and is even more fun to drive. Install was a breeze for the rear but a pain up front, decompressed the eibach springs were longer than stock bullitt springs, so getting them in with the isolators on was a chore, but worth the effort. I debated between these and the H&Rs and I would buy these again, I just wish I got them after AM dropped the price.

    1.5" eibach drop

    January 11, 2010

    No doubt that the springs are great performance wise. It stiffened up the ride, and hitting those tight corners have never been more fun, BUT...was a little disappointed with the 1.5" drop. The gaps between the tires and fenders are still too big. Kinda wish I went with the sportline springs.

    Definately get the shocks to go with this.... Also I think these need to lower the front 1/2 in more cause now the back sits lower than the front.... But it handles great, you dont need to waste your money on the bumpsteer or caster camber plates.... get the shocks and these then drive it and see if you still wanna buy the others after you get an alignment

    These springs will make your Mustang look MEAN! It is a perfect stance. All would I recommend is to buy sub frame connectors to really make you car handle with the best. Not bad at all, thanks American Muscle!!!

    Just right!

    These springs offered the best of both worlds- low enough so that your car doesn\'t look backyard-dropped, but it still has awesome handling capabilities. If you\'re not willing to slam your car to the ground but want the advantages, this is the kit for you!

    Put these on my '98 and looks much better! No more 4x4 look and still a month or two before they completely settle down to their low point. Mine is a daily driver as well and could tell little stiffness to the ride, but nothing close to making it an uncomfortable ride. About an inch difference now, and about a half inch more by the end of the month. But looks great already now!!! Added the chin spoiler afterwords and front end looks sooo much better! A complete 180* !
