You have several options for getting a body kit installed on your car, ranging from professional shops to a DIY project. The best choice depends on your budget, the complexity of the kit, and your desired quality of finish. For a seamless, paint-matched result, a professional automotive customization or collision repair shop is your most reliable bet. If you're experienced with tools, a DIY installation in your own garage is the most cost-effective path, though fitting can be challenging.
The most common and recommended route is a professional installation. These shops have the expertise, tools, and environment to ensure a perfect fit and a high-quality paint job. Look for specialists in aftermarket parts installation or collision repair centers that work with aftermarket components. They can handle everything from test-fitting the parts to blending the new paint with your car's existing color. The cost will be higher, but you're paying for a guaranteed professional outcome.
For the hands-on enthusiast, DIY is an option. This requires a well-ventilated space, proper tools like a drill, sanding equipment, and a rivet gun or automotive adhesive. The process involves test-fitting each piece, making necessary adjustments for alignment, and then permanently mounting them. The final and most critical step is prep and paint, which is often best left to a professional body shop even if you do the installation yourself to ensure a durable, showroom-quality finish.
Here’s a breakdown of typical costs and timeframes for professional installation of a full body kit:
| Body Kit Component | Average Professional Installation & Paint Cost | Typical Timeframe | Key Considerations |
|---|---|---|---|
| Front Bumper | $500 - $1,500 | 1-2 days | Requires precise alignment with headlights and fenders. |
| Rear Bumper | $500 - $1,500 | 1-2 days | May involve fitting with exhaust tips or diffusers. |
| Side Skirts (Pair) | $400 - $1,000 | 1 day | Often involves drilling into the rocker panels. |
| Full Kit (Front, Rear, Sides) | $1,800 - $4,000+ | 3-5 days | Cost varies greatly with kit material (fiberglass vs. polyurethane) and paint complexity. |
| Widebody Fender Kit | $2,000 - $5,000+ | 5-7+ days | Highly complex; often requires cutting original body panels. |

















I’d take it to a custom auto shop, no question. You want people who live and breathe this stuff. They’ve seen it all and know how to make a fiberglass kit look like it rolled off the factory floor. Sure, it’ll cost more than doing it yourself, but you’re paying for peace of mind. A bad install can ruin the whole look of the car. Call a few local shops that specialize in mods and ask to see their portfolio of past work.

If you're handy, your own garage is the best place. You'll need a good set of tools, patience, and a friend to help hold pieces in place. Start by test-fitting everything before you even think about paint or permanent mounting. Be prepared for some sanding and drilling to get the perfect fit. The biggest risk is a sloppy finish, so if you're not confident with the final paint, you can always install the kit yourself and then tow the car to a pro for painting to save some money.

Think about what you want the final product to be. If it's a show car, only a top-tier customization shop will do. For a track car where perfect paint isn't the priority, a solid DIY job might be fine. The material matters, too. Polyurethane kits are more flexible and forgiving for a first-time install than brittle fiberglass. Your best bet is to start on car enthusiast forums for your specific model; owners will have firsthand recommendations for shops and tips for your exact car.

Don't just pick the first shop you find online. Look for one with experience installing the specific brand of kit you bought. Ask them detailed questions: Will they need to modify the kit for fitment? What type of paint and clear coat do they use? Get a written estimate that breaks down labor for fitting, prep, and painting. A reputable shop will be transparent about the process and timeframe. This isn't a quick job; proper fitting and paint curing take time.
