      Improves Power-to-Weight Ratio. Drop weight and move faster with a new Rear Seat Delete Kit for your S197 Coupe Mustang. One of the easiest ways to reduce ET's at the track is to drop unnecessary weight, which will improve your 2005-2010 Mustang's power-to-weight ratio. Deleting your rear seats is like adding free horsepower, just by simply reducing weight.

      Two Seater Appeal. The Mustang Rear Seat Delete Kit for your early S197 coupe replaces your factory rear seats with a sleek, premium black carpeted finish. Tired of friends bumming rides? Now you have a real excuse! Cruise in style with the companion of your choice.

      Quality Construction. The lower two panels of this Rear Seat Delete are made from thick black ABS plastic to absorb heavy weight. The kit is designed to easily support up to 50 lbs of weight without sagging or putting stress on the panel. Whether it be a bottle of nitrous, stereo speakers or taking your pup for a cruise, this rear seat delete won't break or crack under pressure.

      Adds Storage. This Rear Seat Delete Kit creates a hidden storage space under the seat area, where you can easily keep aftermarket stereo equipment or valuables. This gives you some additional cargo space and can help keep things from moving around while cruising.

      Bolt-In Install. Complete with detailed instructions, this Rear Seat Delete is a simple bolt-in that does not require you to remove factory seat brackets or seat belts. If you have a roll-cage, the delete kit can be easily modified to fit.

      Application. This black carpeted Rear Seat Delete Kit is designed to fit all 2005-2010 Mustang Coupes, including the V6, GT, Bullitt and Shelby GT500 models. Not compatible with convertibles.

        Rear seat delete

        The seat delete was of good quality.But the push pin holes in the lower brackets needed modification. Besides that it was fine.

        Seat delete

        The install was very easy. Looks so much better than unusable rear seats. No rattles when driving.

        Alterum rear seat delete

        It looks nice but I feel you have to do a little modification to get it to sit right.

        You won't be overwhelmed

        I installed this item is a short amount of time. Overall the fit isn't great. One half of the bottom is warped and won't sit flat. The back doesn't stay secured to the Velcro and the brackets prevent the back from mating flush. I'm going to have to make modifications to this to improve the appearance and fit. With all that extra work the less expensive seat delete would have been a better choice.

        Rear Seat Delete Not really complete!

        Product looks good and fits well, but could use additional brackets, is "floppy" as is. Included brackets are plastic, would be better out of aluminum. I will be adding some reinforcing brackets. However, I can say I am not dissatisfied with the purchase, just needs "more"!

        BEST Appearance

        Materials are excellent but over time I anticipate the plastic brackets will be replaced with metal, probably aluminum. Usage will dictate any improvements such as bracing, etc. The appearance is outstanding and blends nicely with the stock interior. The black nearly makes it invisible so that you don’t even think, “Back Seat”. Truly a very nice unobtrusive classy delete.

        Oh Boy!

        Since the rear seats are useless this is a PERFECT solution! looks great and gives it a nice sleek look. Here's a life hack too: Get rid of those rear seat belts and you got a 2 seater that can carpool if you cross toll bridges or need access to the carpool lanes with only 2 people. You're welcome lol

        Pretty delete

        This delete kit was very easy to install and looks exactly as pictured. The space created allows for the car seats to be reclined further, which is helpful on longer trips.

      5 Top Rated Questions

      Is there a version of this kit for convertibles? My back seat is never used and it would be nice to eliminate that weight.

      • We do not carry a convertible option of the Rear Seat Delete - Coupe - Black (05-10 All).

      Helpful (1)

      Curious about the strength/durability. Would this be strong enough to support maybe 2 8'' or 10'' subwoofers? Was thinking of cutting 2 holes and mounting woofers in it but curious about the kit's ability to support the weight and/or withstand the vibration of the subs.

      • While the Rear Seat Delete kit is the sturdy seat delete kit we offer, mounting a sub-woofer in the center of the panel may not hold up to the weight. Cutting the panel, especially in the center will weaken it, and the vibrations from the sub-woofer may cause the panel to collapse, depending how hard the sub-woofer hits. If you are looking to cut the panel, I would recommend reinforcing the area, perhaps with aluminum/steel to regain some of the lost strength.

      What are the dimensions for the rear piece?

      This kit is only for coupe as indicated, do you have one for convertibles?

      • Unfortunately, we do not have a rear seat delete kit available for the 05'-10' Convertible Mustangs at this time.

      I’m just wondering if this kit will be able to hold the weight of my midsized husky?

      • The Alterum Rear Seat Delete is designed to give a finished appearance when the rear seat is removed to save weight. Since this is designed to be as light weight as possible, this is not designed to hold weight and would be unable to support a dog.
