    Will these particular Springs work on a 2003 GT convertible? I know there are specific eibach Pro kit convertible springs available for my car, but they get such bad reviews particularly in not lowering the car as advertised. I just need to know if anybody has put this kit on their convertible and what is the actual estimated drop if anybody knows? Thanks for the help!


    • The Eibach Pro-Kit Springs are designed for the convertible V6's and V8 coupes only.

    • Hi, these Eibach Pro-Kit Springs will only work with 79-04 V8's and 99-04 V6 Convertibles because of the spring rates, we do have a set of springs for 79-04 hardtop V6's Item #47501 Here's the link

    Will staggered 20s scrub or bottom out with this kit I have a set of foose speedster wheels on my v8 convertiable and need a spring kit but don't know which one to go with because I don't want to go with a smaller rim and tire with this one work out fine?


    • You will most likely run into rubbing issues with 20" rims and the Eibach Pro-Kit Springs (79-04 V8 Coupe; 99-04 V6 Convertible; Excludes 99-04 Cobra). The biggest wheel that we recommend putting on the 1999 to 2004 body style is an 18" wheel.

    Increased gas mileage Since these drop my car lower to the ground where there will be less air resistance will it really increase my gas mileage or is that a lie?


    • No. Springs will not increase your gas mileage.

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

      Eibach rocks

      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

      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.

      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* !

      At 116k miles my suspension has had it and was due to be replaced.Why not go with a name brand aftermarket one? Eibach has always been #1 in my books,in every car I have these installed. My drop for my 2001 Convertible was 2",which was great for me.The stance is aggressive,the ride quality...surprisingly BETTER because the stocks were just too worn down. Not only did I get the springs.. I matched them with AM's Tokico HP Blue shocks and struts along with Eibach camber bolts. And these pared together=EXCELLENCY! You know that fish tail feeling you get when you go over a bump at 45mph-GONE You know that body roll you get when turning corners fast-GONE You know that annoying THUG in the back when you go over a speed bumb -GONE What about that floating feeling when your going over 55mph-GONE My setup hugs the road. All in all install took 3 hours.Lowered my car 2". And I can still go over speed bumps(slow ofcourse) without any problems. And these all came within 2 days of ordering! I hope this writeup helps. Thank you AM ~Christina

      Great Springs

      I bought these maybe a year ago, and still am very happy with them. Its obvious they arent meant for track/road racing, but mostly for daily driving. They ride very smooth and soft in comparison to stock, and are stiffer than stock so they handle corners better too. Install was basically no problem once i got proper directions. I also only wanted around a 1" drop because of some bad parts of the road around here and thats about what i got on my 2000 v6 convertible.

      These springs are great. It acually made my gt more comfortable to drive, and really helped in those hard corners. Traction from a launch was helped as well.

      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!

      I LOVE these springs!

      These should stock! I hated the 4 inch wheel gap i had on my 96 gt coupe and these springs did lower the car 1.5" inches all around, i measured. Installation was easy just watched youtube videos. Do it yourself. Save money. I just did 120 on the freeway and takes turns amazingly. Doesnt lean at all compared to stock. So much more control. Ride quality is even better than stock. Feel soft on streets, takes turns like a dream These springs gave me a great stance and im so glad i decided to buy them. Bought some 1.5" wheel spacers for the back to get rid of the tucked in wheels. Now my car looks mean. Thanks AM!
