        5 2000 GT - Dart Installation Time: Full Day

        Super comfortable upgrade good looking seats

        I bought these on sale. So, i was happy with that. When I was done the only misgivings I had was the latches on the back of the seats didn't have plates to cover the holes. A very small issue. I've been using these seats now since 9/16 to 05/17. I drive it every workday and some weekends without any issue. Note. when fitting there was no need to modify the angle of head rest to fit. Warm the covers in the sun and cover the foam in slick plastic before zipping them up.

        Love them

        My seats were trashed and I got these and did it myself didn't really come with any instructions or tools I recommend a good set of hog ring plyers and a good friend with some patience they turned out beautiful the front seats sit a little higher tho so be ready for that aswell

        Like any mustang on the far end of its second decade, the interior was due for some tlc. It was a fight to install these seats and a second hand is recommended at times, but overall, I love the way these seats look. Perfect way to make your car feel just a bit more modern.

        I don't know why I didn't order them sooner, They look AWESOME! They are 5 times more comfortable that the original equipment seats. They were not to difficult to install. I have no upholstery training and they went in quite easily. Overall great value, definitely worth 2 to 3 times what they cost. DID I SAY I LOVE THEM???

      Questions & Answers (18 answers)

      5 Top Rated Questions

      Do these seats use the power controls? Are the driver power seat controls still work after installing these seats? Or are the controls lost after installation?

      • This is an upholstery kit so you will be using the original seat and controls. You actually strip the old upholstery off of the seat and reupholster it with the kit.

      Why does this kit say it will not fit the cobras? If the front seat foams are replaced then what is the difference? Is it the rear seat foam?

      • Unfortunately, this kit was made to work with the V6 and GT model mustang and will not fit properly with the Cobra Mustangs due to a few differences between the models including the seat sizes. We apologize for the inconvenience.

      The question was asked about it fitting a power seat and everyone said its just a cover so yes it will....but the drivers power controls are on the bottom front and the power seat is different than non power. So has anyone installed these on a power seat? The TMI pictures show a non power seat.

      • Unfortunately, we do not have any product photos showingthe fitment on the power seats but this upholstery kit will work with the power seat controls on the bottom of the front seats and will not have an issue with fitment when being installed.

      Will these fit with the upgraded head rests that come with the mustangs that got the IUP ( interior upgrade package )

      • The TMI Premium Sport R500 Upholstery & Foam Kit will fit all 1999-2004 Mustang Interiors.

      Is there a video showing how to install the rear seats upholstery?

      • At this time we do not have an installation video available for these seat foam and upholstery covers. These are intended to be installed by a professional interior/upholstery shop and they generally have all the required tools needed for this job. Give us a call at any time if you need assistance with the install process of these kits.

      I don't see convertible as an option like with the other colors. Are you out of stock in the convertible version? 1 answer
      My Mustang convertible seems to have the narrower design of headrest, and does not seem to be adjustable for angle, as the installation guide would appear to suggest. Without this adjustment, will the high back upholstery kit fit my car? Also do American muscle sell a hog ring pliers and hog rings? I've tried searching but have come up blank. Many thanks. Dave. 1 answer
      Does this kit include foam for the rear seat or do I use the pre-existing foam from the OEM seats? 1 answer
      Can we use the exiting seat belts or do we have to get new ones. My seat belt goes through a plastic loup attached to the seat. It doesn't show how my seat belts will fit with this kit 1 answer
      Can anyone simply install this or do you need knowledge and have a upholstery place install it? 1 answer
      Assembly How difficult is the assembly, and disassembly of my stock seats to put these on? Do they come with instructions or am I limited to what's on here? Also does the foam come already inside the leather or do I have it insert it myself? Sorry for the overload of questions, I'm looking to re-do my interior this winter on my 04 V6 and this kit stood out to me! 1 answer
      How hard is it to relace the upholstery and foam? Since I do not see any installation instructions I am wondering from someone that has installed this just how difficult this is. Also are there any special tools needed? 1 answer
      Seat elecrtics How will this seat upholstery work with the seat(s) that have electronic components? 1 answer
