How Much Does It Cost To Widebody A Car?

You can choose to create custom widebody pieces yourself, buy a widebody kit, or take your car to a body shop for a professional package, depending on whether you want to accommodate wider tires or you simply like the look of a wider car body. These choices can cost as little as $300 or as much as $2,000 or more. Additionally, if additional related modifications are required, the overall cost may rise.

How Much Does It Cost to Widebody a Car?

Although widening a vehicle’s body is frequently done to accommodate wider tires, you could also widebody your car for purely aesthetic reasons. There are different ways to make the body of your car wider, and each one has a different cost, amount of work, and quality of modification.

DIY Widebody

The most time-consuming and least expensive way to widebody your car is with this option. You should be aware that this is not a simple project and that you won’t be able to drive the car while the modifications are being made. However, there are a ton of online tutorials and step-by-step guides that can help ensure you are performing the task correctly. It only takes a few expensive or specialized tools to make the change, which is good news. Aside from basic tools like measuring tape and markers, you will probably need the following:

  • Automotive fiberglass: About $1 per square foot.
  • Color-matched paint: Cost depends on paint type, color, finish, etc. You can buy auto body paint at nationwide chains.
  • Foam: Cost varies; you can find sheets of high-density urethane foam for around $130 to $190 at craft stores. You can also find this type of foam at independent foam and plastic manufacturers.
  • Rollers: About $10 to $20 per kit.
  • Resin: About $15 per quart.
  • Sandpaper: Inexpensive at a variety of stores
    • You may want to think about using an electric sander, which is a convenient but more expensive option.

Additionally, if you choose to remove any panels from your car to make it wider, you might want to use an undercoating protector to prevent rust. To help you decide which to use, view our comparison of the most widely used undercoating brands.

Rolling Fenders

Rolling your car’s fenders outward is an easier way to make the car body fit larger wheels or suspension modifications if you’re looking for a simpler DIY project. Although it’s not a true widebody modification, you can make it with a $50 or less fender roller tool. When you roll your car’s fenders, the existing body is essentially bent outward, and the sheet metal around the fenders is reformed. There are videos and online articles that can be found that walk you through the procedure.

Pre-Made Widebody Kits

Although it is more expensive, this option is typically less time-consuming than starting from scratch with a widebody modification. Widebody kits are available from a number of retailers if you have a relatively popular car or truck model, with prices varying by make and model. You can choose to purchase a complete kit or just specific parts, depending on how much you want to modify your car (e.g., fenders, splitters, etc).

Installing these ready-made kits only requires taking off the factory fenders and bolting on the new body kit. The kits are made specifically for each vehicle, so there is no guesswork involved in getting it to fit your car.

The kits will also include comprehensive instructions, and since it’s likely that other people have used the same kit for their car, there may be online discussion forums and instructional videos that can be useful for troubleshooting. Remember that most modifications involve drilling on the fenders and quarter panels, which makes it very challenging to undo the modification.

Body Shops

It will cost more than installing a kit or making your own modification if you take your car to a body shop for a widebody modification, but the work will be thorough and of the highest quality. Depending on how much you want to modify your car, a shop might also be able to complete the work more quickly than you can, resulting in your car being driveable sooner.

Depending on the make and model of your car, the shop you choose, and the degree of the modification, prices will vary greatly. Typically, a relatively simple widebody modification for a common vehicle will cost at least $2,000. You can search for body shops nearby to find a custom body shop and ask for a quote.

Related Modifications

One thing to keep in mind is that if you widen your car to fit wider tires, you might also need to make other changes, like modifying the suspension or installing wheel spacers. These modifications can increase the overall cost of the widebody modification, but you can perform them yourself or have your car serviced. For instance, Advance Auto Parts charges between $18 and $25 for a pair of wheel spacers (between $36 and $50 for all four wheels).

Reversing the Modification

Since the modification might involve drilling or cut into the panels, widening a car body can be challenging and expensive to reverse. Widebody a relatively new vehicle may lower its market value in comparison to an unmodified model, which could affect your ability to resell the vehicle in the future. Before making an expensive modification, keep in mind that almost all car modifications reduce a car’s market value, regardless of how much they cost.


It will be a labor-intensive process, but you might be able to build a widebody modification for your car from scratch for as little as $200 to $300. For the price of a fender roller, you can simply roll out the fenders if that’s all you want to do. Depending on your vehicle and the degree of the modification, you can anticipate spending anywhere from $300 to several thousand dollars to install a pre-made widebody kit. You will typically have to pay at least $2,000 for a basic modification to have the body of your car professionally widened at a shop. Keep in mind that a widebody modification is very hard to undo, and your costs may go up a lot if you need to make more changes that go along with it.
