Introducing an eagerly-anticipated Clinched 2018 Ford Mustang widebody kit!

Our Ford Mustang widebody kit for the newer 2018+ S550-bodied Mustangs is finally ready to hit the streets. S550 Mustang platform has been a big success for Ford ever since its introduction. Ford designers led by Joel Piaskowski found a way to make the body lines look more streamlined without losing Mustang’s signature masculinity.

Our kit is for those looking to stand out from the crowd and those looking for more agression than the stock S550 Mustang provides. This kit is not for the faint of heart – it amplifies Mustang’s design language and also gives you ability to run much bigger wheels and tires. Our kit for 2015-2017 Mustangs has been our best-selling kit. We’re now ready to follow up with a release of this 2018+ Ford Mustang widebody kit.

Adds 3.6 inches(9cm) up front and 4.7 inches(12cm) out back per side.

Parts included in this 2018 Mustang widebody kit:

– Set of front and rear fender flares (4 pcs);
– Front add-on lip (2-piece design) – mounts to the stock front bumper;
– Front bumper flares;
– Sideskirts (2-piece design);
– Ducktail spoiler (could be sold without a spoiler for customers looking to use other type of rear spoiler);
– Rubber gasket;
– Mounting hardware

This Ford Mustang widebody kit is superior to most of the kits out there and is offered in ABS plastic. You won’t have to pay thousands of dollars in labor to your body shop to make it “fit”, like with any fiberglass kits. Unlike fiberglass, our parts won’t crack and will have a much longer lifespan. Most of the original equipment bumpers are made out of ABS plastic and there’s a reason for that – parts made out of ABS plastic are very heat, chemical and impact resistant and they require the least amount of prep work prior to being painted and mounted.

Our partners Pazi Performance were able to complete 3 Mustangs for SEMA Show in just 3 (long) days. This feat would’ve been impossible to pull off with fiberglass parts.


Our 2018 Ford Mustang widebody kit will fit all variations of 2018+ S550-bodied Ford Mustang. The kit will fit both coupe and convertible bodystyles of GT and EcoBoost models. It will also fit GT350 and GT350R with some additional custom work on the front bumper flares and front lip.

This 2018 Ford Mustang widebody kit comes with mounting hardware (Type 3) and rubber gaskets. For those customers looking to mount the kit with different style of hardware we offer a choice of Type 1 and  Type 2  mounting hardware. The type of mounting hardware is nothing more than a personal choice.

Please note – you will be required to cut your existing fenders and quarter panels. We highly recommend professional installation, although some of our clients have been succesful with DIY installations.

All parts come in unpainted black ABS plastic. You can paint or wrap the kit. In either case, you will need to primer the parts first.

Wheels & Tires.

www.willtheyfit.com is a good first step to figuring out possible wheel and tire combos.

As a point of reference – a now-infamous satin black Mustang as seen @ SEMA ’17 is running 20×13 wheels (negative 50 offset) out back with 315/30/20 tires and there’s TONS of room left on the inside. You can run 345/25/20 tire on a 13.5 ET-44 wheel.

Front wheel size is 20×11.5 ET-45 and the optimal tire size is 295/30/20 or 315/25/20.

  1. Eason

    Hi wanna ask will this fot on the 2018 ecoboost mustang

    • Michael Kazakov

      Yes it will

  2. Nolan Caduff

    Hi i wanna ask if its possible to have this kit in carbon?

    • Michael Kazakov

      Theoretically-speaking YES. We have molds for the most of the kit but not for the front clip. We can make the molds if there’s interest

  3. michel grandoff

    what spacers could u use if u wanted to put the car on air suspenstion

    • Michael Kazakov

      You would need different wheels. No spacers are going to push the stock wheels far enough to fill in those new flares

  4. DJ

    what wheels will be a good option to put on this any links?

    • Michael Kazakov

      You will need custom 3-piece wheels. No off-the shelf wheels will fit. You will need something close to 20×12 + 20×13 wheels. BC Forged, Rennen Forged, AG Wheels are all very familiar with the specs. but we can help out if you decide to go with any other company

  5. Troy Hicks

    Could this fit on my 2019 mustang GT?

    • Michael Kazakov

      Yes it will

  6. Sebastian Lozano

    I just recently bought my Mustang GT and the first thing I want to do is make it a wide body, do I need to add something or change something in my vehicle to add the wife body kit?

    • Michael Kazakov

      Yes, you would need to change out the wheels as pushing out your existing wheels with spacers is not going to be sufficient for our kit

  7. Wez

    I was wondering if the package comes with the rear window Louvers, also do I have to get a air suspension prior to getting this package ?

    • Michael Kazakov

      It does NOT come with the louvers. Air suspension is recommended but not required

  8. John Davis

    Will this fit on the 2019 Mustang Bullitt? Also, will it fit on the 2019 Mustang GT Premium Convertible?

  9. Robert

    Will this kit fit a 2015 mustang convertible with a 2018 front end swap ?

    • Michael K.

      Yes it will

  10. Robert

    Will this fit a 2015 mustang convertible with a front 2018 conversion ?

    • Michael K.

      Yes it will

  11. Adrian N.

    What type of wheel spacer would I need?

    • Michael K.

      Sorry but wheel spacers won’t do it with our kit. You need a set of custom 3-piece wheels

  12. Barry

    I’m in the UK. I have the 2018 GT convertible. Do you ship to the UK? and can you give me the total width dimensions as UK roads are mostly not motorways…….

    • Michael K.

      Yes, we ship to UK, just recently shipped a kit. Total width with a kit for a 2018 GT is 84.6″

  13. Michael H

    HI! I love the wheels in the images of the green mustang. I was wondering if someone could tell me the exact model name for them. Thank you!

  14. Jonathan

    Would you be willing to help me purchase the correct modifications to be able to fit this body kit onto my stock ‘19 GT? From the 3-piece wheels, to specific rims and finally the body kit.


    • Michael K.

      Yes, potentially. Where are you located?

  15. Ryan Morris

    What offset would you reccomend to fit a 11-12 inch rear wheel with a 10 inch front with 315/35/20
    And 275/35/20 tires on? Would wheel spacers still be needed for this set up. Car will also be on bags

    • Michael K.

      Use -60 offset up front and -55 out back (when using a 12-inch rear wheel)

  16. Jake R.

    What tyre settup should I run with this, also what set of coilovers or air suspension would work best. Thanks!

    • Michael K.

      Most customers use some sort of air suspension – AirLift or Accuair being the most common. Most customers use 20×11.5 + 20×13 wheels with -45 offset all around. Tires are usually 285 or 295 front and anywhere from 325 to 355 rear

  17. Tristen Marengo

    will this fit on the new GT500?

    • Michael K.

      Will require custom modification of front bumper elements and front lip

    • Egor Malinka

    How wide dose the car gets once it is installed?

    • Egor Malinka

      Adds 3.6 inches(9cm) up front and 4.7 inches(12cm) out back per side

  22. Yiming Zhu

    Are there any certified auto shop installers in AZ?

      Rear 20×13.5J -45 or 13J -50

  24. Cameron Powell

    I’ve got everything on. My wheels and tires don’t let me turn past 90 degrees. My car isn’t lowered and I’m not planning on dropping it. I have
    Tire size:

    Wheel size:
    20 height x 10 front
    20 height x 14 back

    Offset:-52,-31. What’s the problem u think? My offset? The only tires that run is my front tires. Back tires fit nicely and are flush…

  25. Severy

    Will this fit on a 2020 Ford Mustang GT

    • Egor Malinka

      Yes, it will fit!
